MEMORANDUM AND ORDER
This еase has been assigned to me for the resolution of discovery disputes pursuant to 28 U.S.C. § 636(c) (1993) and Local Rule 301 (D.Md.1997). The plaintiff, a former police officer, has sued Glock, Inc., the manufacturer of the Glock 9mm semiautomatic pistol. The plaintiff alleges that she sustained serious injuries as a result of the defective design of a carrying case for the Glock pistol which, it is claimed, caused the pistol to discharge while the plaintiff was.attempting to put it in its carrying ease following a training session.
Presently pending is the defendant’s motion to exclude testimony of plaintiffs expert witnesses, the plaintiffs opposition and the defendant’s reply. Paper Nos. 41, 42 and 43.
BACKGROUND
In its motion to exclude the plaintiffs expert testimony, the defendant concedes that the plaintiff disclosed the identity of her health care experts, but asserts that these disclosures were inadequate. The disclosure identified the following health care experts: Yomi Fakunle, M.D.; Lesley Wong, M.D.; Jerome F. Kowaleski, Ph.D., a psychologist; Lois Bethea-Thompson, a physical therapist; and Diane Doyle, an occupational therapist. During a telephone conference with counsel on September 17, 1997, counsel for the plaintiff stated that each of these health care experts provided services for, and treatment of, the plaintiff. According to plaintiffs counsel, none of the health care experts were retained for the purpose of providing testimony at trial.

DISCUSSION
Since the adoption of the Federal Rules of Evidence in 1975, the use of expert witnesses in civil and criminal trials has exploded. One commentator has observed:
In modern trials, the expert is as common as the lawyer. Case after case, civil or criminal, state or federal, turns on the testimony of one or more of many kinds of experts. Expert inflation is on the rise. The causes аre many. The growth of complex litigation, the explosion of technology and science, the increasing creativity of advocates — all play a role. But the main reason is the liberality with which modern evidence doctrine embraces courtroom experts.
Faust F. Rossi, Modem Evidence and the Expert Witness, in The Litigation Manual: A Primer for Trial Lawyers 254 (2d ed.1989).
The Federal Rules of Civil Procedure regarding discovery of expert witness opinions .have had to change to keep pace with the increasing use of expert testimony. Prior to the 1993 amendments to the Rules, there was no right to take the deposition of an expert retained to testify at trial, without leave of the court.
In recognition of the need for lawyers to have an effective means of discovering expert testimony, the 1993 changes to the Rules of Civil Procedure adopted a carefully considered series of procedures designed to facilitate meaningful, and less expensive, discovery of expert opinions. The “expert disclosures” required by Fed.R.Civ.P. 26(a)(2) are the cornerstone of these changes. The Rule provides, relevantly:
(2) Disclosure of Expert Testimony.
(A) In addition to the disclosures required by paragraph (1), a party will disclose to other parties the identity of any person who may be used at trial to present evidence under Rules 702, 703, or 705 of the Federal Rules of Evidence.
(B) Except as otherwise stipulated or directed by the court, this disclosure shall, with respect to a witness who is retained or specially employed to provide expert testimony in the case or whose duties as
Fed.R.Civ.P. 26(a)(2).
It is noteworthy that Rule 26(a)(2) creates two distinct types of disclosures: (1) disclosure of the identity of any witness who may provide opinion testimony at trial in accordance with Fed. R. Evid. 702, 703, and 705; and (2) the far more comprehensive written and signed report which Rule 26(a)(2)(B) requires for “a witness who is retained or specially employed to provide expert testimony in the case or whose duties as an employee of the party regularly involve giving expert testimony” (hereinafter, “retained experts”). This distinction, often overlooked in practice, is of critical importance. Rule 26(a)(2)(A) is colloquially said to apply to “hybrid” fact/expert witnesses, the most frequent example being a treating physician in a personal injury ease.
The requirement of a written report in paragraph [26(a) ](2)(B), however, applies only to those experts who are retained or specially employed to provide such testimony in the case or whose duties as an employee of a party regularly involve the giving of such testimony. A treating physician, for example, can be deposed or called to testify at trial without any requirement for a written report.
Commentary to Fed.R.Civ.P. 26(a) (1993),
Although it is clear that a treating рhysician is the quintessential example of a hybrid witness for whom no Rule 26(a)(2)(B) disclosures are required, it is a mistake to focus solely on the status of the expert, instead of the nature of the testimony which will be offered at trial. A witness can be a hybrid witness as to certain opinions, but a retained expert as to others, and with regard to treating physicians, there is a debate over where the line should be drawn. Compare Shapardon v. West Beach Estates,
The failure to appreciate the distinction between a hybrid witness and retained expert can be a trap for the unwary. In this case, for example, the plaintiff disclosed the identity of a number of experts who were also her treating health care providers, and hence, hybrid witnesses, but did not provide — and was not required to provide — the detailed disclosures mandated by Fed. R.Civ.P. 26(a)(2)(B). Not appreciating the distinction between hybrid witnesses and retained experts, defendant’s counsel repeatedly demanded complete Rule 26(a)(2)(B) disclosures, when she was not entitled to receive them.
As noted above, however, the plaintiff was not required to disclose any more than the identity of the hybrid witnesses under Rule 26(a)(2)(A), which she did. Thus, the automatic exclusion provision of Rule 37(e)(1) is inapplicable. Under an overly rigid reading of the rules of procedure, which I decline to do, the trap for the defendant would be that it would now be required to go to trial without any knowledge of the plaintiffs hybrid witnesses’ opinions, because the discovery deadline has passed, and, without leave of the Court, the defendant would be unable to depose them.
Discovery of expert opinion testimony may also be obtained by interrogatories under Rule 26(b)(4)(B), and by deposition under Rules 26(b)(4)(A) and 26(b)(4)(B).
Another reason for potential confusion regarding the sufficiency of disclosure of expert opinion testimony is that Rule 26(e)(1) requires that, with respect to the retained expert, there is a duty to supplement the expert’s opinion if there is a material change in the opinion. This obligation extends to both the report required by Rule 26(a)(2)(B), as well as the expert’s deposition testimony. This supplementation must occur not later than the date of the pretrial disclosures required by Rule 26(a)(3).
Another issue which frequently arises in connection with discovery of expert opinions is the sufficiency of the disclosures required by Rule 26(a)(2)(B). See, e.g., 1st Source Bank v. First Resource Federal Credit Union,
Thus, given the severity of the automatic exclusion sanction of Rule 37(c)(1), prudence dictates that counsel be as complete and thorough as possible in making and supplementing Rule 26(a)(2)(B) disclosures. Accord 1st Source Bank,
Pursuant to Fed.R.Civ.P. 37(a)(2), a party who is not provided a Rule 26(a)(2)(B) disclosure, or receives one which he or she thinks is incomplete, may file a “motion to compel disclosure and for appropriate sanctions.”
A party who receives incomplete оr evasive Rule 26(a)(2) disclosures consequently faces a dilemma of sorts. Because the failure to completely and nonevasively respond operates as a refusal to answer, the “self-executing” exclusion of the expert’s opinion is mandated, without further motion by the party, unless the court determines that the defective disclosure was substantially justified or harmless. Attorneys who wish to exclude the expert’s testimony at trial, then, may be disinclined to file the motion to compel, because, if granted, the party which supplied the defective disclosures may be given another opportunity to get them right, and the expert will then be permitted to testify at trial. Furthermore, as a practical matter, filing a motion to compel can have the effect of educating an opponent as to what corrective measures must be taken in order to secure admission at trial of some of the potentially most damaging evidence which can be offered. On the other side of the coin, if the attorney does not file a motion to compel, he or she does so at the risk of the judge permitting the expert to testify, finding that the failure to properly provide the Rule 26(a)(2) disclosures was substantially justified or harmless. See, e.g., Marek v. Moore,
When counsel foregoes filing a motion to compel, anticipating that the trial judge will exclude the expert testimony on the basis of inadequate 26(a)(2) disclosures, and files a motion in limine to block the testimony at trial, the court must decide whether to impose what has traditionally been considered a severe sanction, appropriate only for willful and substantial abuse of the discovery process. See McNerney v. Archer Daniels Midland Co.,
Contrastingly, if the court decides to grant the motion in limine and exclude the challenged expert’s testimony as to undisclosed opinions, it may seriously weaken the case of the party sponsoring the witness under circumstances where the opposing party had actual knowledge before the discovery cutoff that the expert would be offered at trial, yet received incomplete disclosures about the full nature of the opinions. It is tempting, under such circumstances, to wonder why the opposing party didn’t file a motion to compel adequate disclosure under Rule' 37(a)(2)(a), or simply take the deposition of thе expert, even though that party was well within its rights not to do so, and to elect to take the position that Rule 37(c)(1) bars the testimony at trial.
In attempting to decide whether or not the court can, in the exercise of its discretion, allow the challenged expert to testify at trial despite incomplete disclosures under Rule 26(a)(2), the court may look for guidance to the many reported decisions on this issue. However, when it does so, it will quickly discover that, as at “Alice’s Restaurant,” one can find what one wants.
The first rule of reason is that the entire structure of the rules of procedure governing pretrial preparation, expert disclosures under Rule 26(a)(2) and discovery in general, underscore the need for a fixed period of discovery which ends at a date certain well before trial. Thus, last minute discovery should be strongly discouraged, absent truly exigent circumstances.
Second, there is an important interrelationship between the expert disclosures required by Rule 26(a)(2) and the other forms of discovery which must be recognized by counsel, who are obligated to comply with all of the requirements for each component, or risk the adverse consequences of failing to do so. Therefore, it is incumbent upon counsel to make full and timely disclosures of information regarding their retained experts, supplement them promptly when required,
Third, counsel must be familiar with the distinction between hybrid witnesses and expert witnesses, and the significance of this difference with respect to the required disclosures of Rule 26(a)(2). The written report required by Rule 26(a)(2)(B) is inapplicable to hybrid witnesses, and counsel must be prepared to obtain information about the opinions and bases of their testimony by interrogatories and/or depositions. The failure to pursue these alternative means of discovering the expected opinion testimony of hybrid witnesses is not a basis for excluding that testimony at trial.
Fourth, when faced with a situation where no required expert disclosures have been made, or materially incomplete disclosures have been made, counsel must make a tactical decision. If the most important goal is to avoid surprise at trial or last minute discovery about expert testimony on the eve of trial, then counsel should consider filing a motion to compel adequate disclosures or in the alternative to exclude expert testimony as soon as possible following the discovery cutoff, sо that if the court declines to exclude the expert’s testimony, the opinions of that expert may be discovered, and a rebuttal expert engaged as far as possible ahead of trial. Alternatively, if the most important goal of the attorney is to preclude the expert from testifying at trial by evoking the automatic exclusion provisions of Rule 37(c)(1), he or she should remember that this course is not risk free, and that the exclusion of evidence is a severe sanction which the court may be reluctant to impose despite Rule 37(c)(1). At least one court, for example, has recently refused to strike an expert’s testimony for failing to comply with Rule 26(a)(2)(B) disclosures where the party moving for exclusion waited until the day before the discovery cut-off to challenge the adequacy of the report. See Harvey v. District of Columbia,
' Fifth, in determining whether or not the automatic exclusion provisions of Rule 37(c)(1) should be applied to exclude expert testimony, the court should consider four factors in assessing whether there was substantial justification for the failure to disclose or harmlessness to the opposing party: (1)
With respect to the second factor, the court should take into consideration the reason for the failure to make the disclosure. The court may consider, for example, the experience of counsel, and whether the failure to provide appropriate disclosures was willful or in bad faith as opposed to inadvertent or the result of inexperience. The court might consider whether any of the confusing circumstances discussed above were involved; whether opposing counsel wrote to request the required disclosure or protest the adequacy of the disclosure given; whether the failure was total as opposed to an incomplete disclosure or failure to timely supplement; and whether the information required by the disclosure was provided to opposing counsel by some other discovery method. In this regard, at least one court has recently also taken into consideration the fact that Rule 26(a)(2) disclosures are relatively new. See Reed v. Binder,
The third factor requires the court to consider the potential prejudice to the opposing party if the expert is allowed to testify. Perhaps the most important consideration in this regard is the amount of time remaining before trial. If the issue surfaces months before trial, the court has great latitude to require the disclosure, permit the opposing party to take additional discovery and designate rebuttal experts, and to balance the scales by imposing a lesser sanction, such as awarding costs. See McNerney v. Archer Daniels Midland Co.,
The final factor the court should consider is whether a continuance may be granted to cure the effects of prejudice caused by a failure to disclose, or a late disclosure. Needless to say, if the issue arises months before a scheduled trial date, this remedy is far more palatable than if it arises on the eve of trial. Courts should be mindful that granting a continuance just before a scheduled trial inconveniences not only the attorneys and parties, but also non-party witnesses. Additionally, a court must be careful not to reward the party who failed to make proper disclosures by granting a continuance, a practice which invites abuse.
CONCLUSION
In light of the above discussion, it is apparent that, to the extent that the health care experts identified by the plaintiff in her Rule 26(a)(2)(A) disclosures are intended to testify at trial regarding their treatment of the plaintiff, any opinions regarding the existence of her medical condition, its causation, her treatment and prognosis, then they are hybrid witnesses and the plaintiff was not obliged to provide the defendant with the comprehensive disclosures required under Rule 26(a)(2)(B). Accordingly, the disclosure of their identities complies with the federal rules. For this reason, the defendant’s motion is DENIED. However, to the extent that the plaintiff intends for these witnesses to offer opinion testimony based on facts not obtained from their actual treatment of the plaintiff, they may not do so unless complete Rule 26(a)(2)(B) disclosures have been made. Because trial is some months away, there remains time to permit the reopening of discovery for the limited purpose of permitting the defendant to depose the plaintiffs health care experts. To insure that this is accomplished effectively, the following schedule will apply: Within 30 days of this Order, the defendant shall take the deposition of the plaintiffs health care experts. Within 21 days thereafter, the defendant shall designate any rebuttal experts. Within 30 days thereafter, the plaintiff may take the deposition of such rebuttal experts.
SO ORDERED.
Notes
. The defendant also has sought to exclude the trial testimony of another of the plaintiff's experts, Mr. Roane, as part of the relief requested in its motion for summary judgment. Paper No. 38. This issue will be addressed in a separate Order.
. The disclosure statement is attached as Exhibit A to the defendant’s motion. Paper No. 41.
. Prior to the 1993 amendments, Rule 26(b)(4) limited discovery of testifying experts to interrogatories, but provided that, upon motion, "the court may order further discovery by other means....” Fed.R.Civ.P. 26(b)(4)(A)(i) (superseded). In practice, this was one of the most ignored rules of civil procedure. Recognizing the hardship thаt strict adherence to the rule would impose upon efficient pretrial preparation, this Court accordingly adopted a Local Rule stating that it was "[t]he general practice in this District to permit experts designated by one party to be deposed by an opposing party.” Local Rule 104.10 (D.Md.1989) (superseded).
. See Local Rule 104.10.b (D.Md.1997) (indicating that "hybrid fact/expert witnesses” include treating physicians).
. Although the treating physician is the most frequent example of a hybrid witness, it is clear from a review of Fed.R.Evid. 702 that any witness with expertise in an area of scientific, technical or specialized knowledge which would be helpful to the fact finder would fit into this category as well. It is very common in modern litigation to find fact witnesses who also possess the requisite expertise required by Fed.R.Evid. 702 to permit them to give expert opinion testimony. While Rule 26(a)(2)(A) does not require disclosure of anything more than their identity, lawyers still need to discover their opinions in order to effectively prepare for trial.
. From a review of the papers submitted in connection with this dispute it does not appear that counsel for the plaintiff was aware of the distinction between hybrid witnesses and retained experts either. His failure to provide more detailed information about his experts in response to counsel for the defendant’s many demands appears to be more a function of inattention to her requests, rather than an understanding of the rules of procedure.
From the papers filed in connection with this dispute, I do not know whether counsel for the defendant propounded an interrogatory question to the plaintiff asking for the opinions and factual bases of all witnesses who would provide opinion testimony pursuant to Fed.R.Evid. 702,
. A party does not waive its entitlement to Rule 26(a)(2)(B) disclosures merely by filing interrogatories or deposing an expert. Brand v. Mazda Motor Inc., No. 95-4139-SAC,
. Rule 26(a)(3) requires that pretrial disclosures be made not later than 30 days before trial, unless otherwise required by the court. Local Rule 106.4, which governs pretrial orders, provides that disclosure of the information required by the pretrial order satisfies the requirements of Rule 26(a)(3). Thus, in this jurisdiction, if supplementation of an expert’s deposition testimony is required by Rule 26(e)(1), it must be done not later that the time designated in the scheduling order for filing the joint pretrial order.
. "[A]n evasive or incomplete disclosure, answer, or response is to be treated as a failure to disclose, answer or respond.” Fed.R.Civ.P. 37(a)(3) (emphasis added).
. When one understands the purpose of the Rule 26(a)(2)(B) disclosures, it is easier to appreciate why complete disclosures are required. The purpose of these disclosures is to provide “information regarding expert testimony sufficiently in advance of trial that opposing parties have a reasonable opportunity to prepare for effective cross examination and perhaps arrange for expert testimony from other witnesses." Commentary to Rule 26(a),
. Of course, counsel must first make a good faith attempt to confer with opposing counsel to obtain the disclosures before filing a motion to compel. Fed.R.Civ.P. 37(a)(2)(A); Local Rule 104.7 (D.Md.1997).

. See Arlo Guthrie, "Alice’s Restaurant” (Reprise Records, 1967) (“You can get anything you want at Alice's Restaurant."). To date, however, neither the Fourth Circuit nor this Court appears to have interpreted in a published opinion the appropriateness of excluding expert testimony for the failure to comply with Rule 26(a)(2).
. To avoid disputes about whether Rule 26(a)(2) disclosures were supplemented as required, this should be done in a writing which clearly reflects that the disclosures are being supplemented.
