OPINION
I. Introduction
This case involves an arbitration dispute between Wee Tots Pediatrics, P.A. and Adunni Morohunfola, M.D. Wee Tots filed a motion to compel arbitration of certain counterclaims and third-party claims and to abate the proceedings on the counterclaims and third party claims pending arbitration. The trial court denied Wee Tots’s motion; the trial court’s denial order did not state a reason for the denial, and the court did not make any findings or conclusions in the order or in a separate document.
Wee Tots thereafter filed an interlocutory appeal, cause no. 2-08-178-CV, and a mandamus proceeding, cause no. 2-08-246-CV, challenging the trial court’s denial of its motion to compel arbitration. We consolidated these proceedings and requested a response from Dr. Morohunfola in the mandamus proceeding. 1
We conditionally grant Wee Tots’s requested relief in the mandamus proceeding because we hold that the trial court abused its discretion by denying Wee Tots’s motion to compel arbitration under the Federal Arbitration Act (“FAA”). We dismiss the appeal as moot.
*788 II. Factual and PROCEDURAL Background
Dr. Morohunfola signed an “Associate Physician Employment Agreement” (“Agreement”) with Wee Tots that set forth various terms and conditions, among other things, of her employment with Wee Tots. The agreement lasted for three years-from September 1, 2003, to August 31, 2006.
Section 4.03 of the Agreement, “Restrictive Covenant,” provides that Dr. Mo-rohunfola agrees to the covenant not to compete set forth in Schedule D. The covenant in Schedule D provides in part the following:
[Dr. Morohunfola] agrees that during [her] employment with [Wee Tots] and for a period of twelve (12) months after the date [of] cessation of [Wee Tots’s] employment for any reason, [Dr. Moro-hunfola] will not engage in or become associated with, directly or indirectly, a pediatric group practice, physician-hospital organization, managed care entity, or other health care provider....
The covenant not to compete contains a geographic limitation limiting the covenant to a twenty-five mile radius of the site where Dr. Morohunfola practiced.
Section 4.05 of the Agreement, “Confidentiality of Information,” is a covenant apparently intended to protect Wee Tots’s confidential and proprietary information and trade secrets. The provision states that Dr. Morohunfola “agrees not to disclose such Confidential Information to others at any time, except as expressly required by [Wee Tots] or by law.”
Section 3.01, “Compensation,” provides that Wee Tots shall pay Dr. Morohunfola compensation set forth in Schedule A. In addition to base compensation, Schedule A provides that Dr. Morohunfola is “entitled to annual incentive compensation based upon the collections actually received by [Wee Tots] for services rendered personally by [Dr. Morohunfola].” [Emphasis added.]
Section 7.08, “Arbitration,” provides in part as follows:
All controversies which may arise between the parties, including but not limited to any dispute arising over the terms and conditions of this Agreement or in any manner relating to this Agreement, or any other agreement between the parties, whether entered into prior to or subsequent to the date hereof, which the parties are unable to resolve informally between themselves or by mediation, shall be submitted upon the unitten demand of either party to arbitration under the Employment Arbitration Rules of the American Arbitration Association (“AAA”) in effect at the time of the arbitration demand.
The parties expressly agree that this arbitration clause shall not apply [to] a dispute over any right of the Association to seek an injunction or other relief in Court as referred to in Sections j.03, 4..05 and Schedule D attached hereto. [the covenant not to compete and confidentiality agreement]
Physician acknowledges that the duties of Physician’s employment with the Association affect interstate commerce in that Physician will be, among other things, dispensing medications, devices and other material manufactured out of state to patients in Texas, some of whom may travel from other states before being treated....
All arbitration proceedings shall be administered by the AAA and be held in the AAA’s Dallas, Texas office.... [Emphasis added.]
Wee Tots’s first amended petition alleges that Dr. Morohunfola worked for Wee Tots at its Arlington location until the Agreement expired and that it subsequent *789 ly became aware that she joined Tots and Tykes Pediatrics, P.A., another pediatric practice in Tarrant County. Wee Tots alleged that on November 26, 2006, and December 3, 2006, an advertisement was published in the Arlington edition of the Fort Worth Star-Telegram for Tots and Tykes Pediatrics, P.A. that included Dr. Morohunfola’s name. It further alleged that Dr. Morohunfola “is engaging in a pediatric practice within the geographic limitation set forth in Schedule D to the Employment Agreement, and is, in fact, actively soliciting [Wee Tots’s] patients in the Arlington area in direct violation of the Employment Agreement.” Wee Tots alleged causes of action for breach of the covenant not to compete, breach of the confidentiality covenant, tortious interference with existing contractual and business relations, and civil conspiracy.
Dr. Morohunfola’s second amended counter-petition, filed on October 17, 2008, alleged causes of action against Relator for breach of contract, breach of fiduciary relationship, fraud, and fraud in the inducement. All of the claims implicate in part the “incentive compensation” provision in Schedule A of the Agreement. 2
According to Wee Tots, the parties unsuccessfully mediated their disputes on October 10, 2007. On October 19, 2007, Wee Tots filed its motion to compel arbitration of Dr. Morohunfola’s counterclaims and to abate proceedings of the counterclaims pending arbitration. The trial court denied Wee Tots’s motion on April 10, 2008. Wee Tots filed its notice of interlocutory appeal on April 30, 2008, and this original proceeding on June 11, 2008.
III. Mandamus Proceeding Jurisdiction
In Texas, a trial court’s denial of arbitration under the FAA may be challenged only by mandamus and not by interlocutory appeal.
In re D. Wilson Constr. Co.,
The FAA governs a contract evidencing a transaction involving interstate commerce if the contract contains a written arbitration provision.
In re Scott,
Here, the Agreement does not specifically state that it is governed by the FAA, but Wee Tots directs us to Dr. Mo-rohunfola’s express acknowledgment in the arbitration portion of the Agreement that the duties associated with her employment “affect interstate commerce” and that she will be, among other things, “dispensing medications, devices[,] and other material manufactured out of state to patients in Texas, some of whom may travel from other states before being treated.” As evidenced by her signature at the conclusion of the Agreement, Dr. Morohunfola agreed to this provision, which is a reference unambiguously implicating the FAA. Dr. Morohunfola does not challenge the application of the FAA to the Agreement. Accordingly, we hold that the dispute between the parties involves arbitration under the FAA.

IV. Wee Tots Entitled to Arbitration Under FAA
In its first issue, Wee Tots argues that the trial court abused its discretion by denying its motion to compel arbitration because Dr. Morohunfola’s counterclaims fall within the express scope of the Agreement’s arbitration clause.
Federal and state law strongly favor arbitration.
Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp.,
A party attempting to compel arbitration must establish a valid arbitration agreement whose scope includes the claims asserted.
In re Dillard Dep’t. Stores, Inc.,
Here, the Agreement — which is governed by the FAA and signed by Dr. Morohunfola — contains an arbitration clause providing in relevant part as follows:
*791 [a]ll controversies which may arise between the parties, including but not limited to any dispute arising over the terms and conditions of this Agreement or in any manner relating to this Agreement, ... which the parties are unable to resolve informally between themselves or by mediation, shall be submitted upon the written demand of either party to arbitration .... ” [Emphasis added.]
Dr. Morohunfola’s breach of contract, breach of fiduciary relationship, fraud, and fraud in the inducement counterclaims fall within the broad scope of the arbitration agreement requiring arbitration of “all controversies which may arise between the parties,” including disputes arising “in any manner” relating to the Agreement. Nor do Dr. Morohunfola’s counterclaims fall within the exclusionary portion of the arbitration clause, which provides that the “arbitration clause shall not apply [to] a dispute over any right of the Association to seek an injunction or other relief in Court as referred to in Sections 4.03, 4.05 and Schedule D attached hereto,” because the counterclaims do not concern the covenant not to compete and confidentiality portions of the Agreement. Accordingly, we hold that Wee Tots established a valid arbitration agreement subject to the FAA and covering Dr. Morohunfola’s counterclaims.
Dr. Morohunfola argues that the trial court did not err by denying Wee Tots’s motion to compel arbitration because the claims that Wee Tots seeks to litigate are the same as the claims that Wee Tots seeks to arbitrate. Consequently, according to Dr. Morohunfola, the exact same issues cannot be properly decided in two forums because this might “require two distinct forums to decide at least some of the exact issues separately.” Wee Tots’s claims for breach of the covenant not to compete and breach of the confidentiality agreement are not the same claims as Dr. Morohunfola’s claims for breach of contract for failing to pay her “incentive compensation,” breach of fiduciary duty, fraud, and fraud in the inducement. They are entirely different causes of action, and a cursory reading of the parties’ respective pleadings demonstrates that Dr. Morohun-fola’s counterclaims, which center largely around the issue of Wee Tots’s alleged non-payment of “incentive compensation,” do not implicate much, if any, of the same facts forming the basis of Wee Tots’s breach of the covenant not to compete and breach of the confidentiality agreement claims, which focus on Dr. Morohunfola’s alleged conduct.
To the extent a situation might arise as contemplated by Dr. Morohunfola in which “two distinct forums [will be required] to decide at least some of the same issues separately,” we observe that Dr. Morohunfola signed and agreed to the Agreement as written, including the arbitration clause. “[A] person who signs a contract must be held to have known what words were used in the contract and to have known their meaning, and he must be held to have known and fully comprehended the legal effect of the contract.”
Tamez v. Sw. Motor Transp., Inc.,
Relying on the factors set forth in
Perry Homes v. Cull,
Dr. Morohunfola additionally argues that the trial court did not err by denying Wee Tots’s motion to compel arbitration because, according to the totality of the circumstances of the case, Wee Tots waived its right to arbitration.
The test for determining waiver of arbitration is two pronged: (1) did the party seeking arbitration substantially invoke the judicial process, and (2) did the opposing party prove that it suffered prejudice as a result.
Nw. Constr. Co., Inc., v. Oak Partners, L.P.,
In this case, Wee Tots served nineteen interrogatories, sixteen requests for admissions, and thirty-nine requests for production before seeking arbitration, but the discovery does not focus solely on the non-arbitrable claims. Wee Tots also filed a partial motion for summary judgment, but it sought judgment only on its claim for breach of the covenant not to compete, not on its arbitrable claims. Dr. Morohunfola acknowledges that a large portion of the discovery would be useful in arbitration. And Wee Tots claims that it sought to compel arbitration only after mediation failed. We resolve any doubts that we have regarding waiver in favor of arbitration.
See Oak Partners,
In light of the above, we hold that the trial court had no discretion but to compel arbitration of Dr. Morohunfola’s counterclaims and the third-party claims.
See FirstMerit Bank,
*793 V. Abatement
In its second issue, Wee Tots argues that the trial court abused its discretion by denying Wee Tot’s motion to abate the arbitrable claims and stay the same claims in the trial court pending arbitration.
9 U.S.C.A. § 3 provides as follows:
If any suit or proceeding be brought in any of the courts of the United States upon any issue referable to arbitration under an agreement in writing for such arbitration, the court in which such suit is pending, upon being satisfied that the issue involved in such suit or proceeding is referable to arbitration under such an agreement, shall on application of one of the parties stay the trial of the action until such arbitration has been had in accordance with the terms of the agreement, providing the applicant for the stay is not in default in proceeding with such arbitration.
9 U.S.C.A. § 3. Both the federal and Texas arbitration acts require courts to stay litigation of issues that are subject to arbitration.
In re Merrill Lynch Trust Co. FSB,
Here, having determined that the trial court abused its discretion by denying Wee Tots’s motion to compel arbitration, the trial court also abused its discretion by denying the portion of Wee Tots’s motion seeking to abate the arbitrable claims. We therefore sustain Wee Tots’s second issue.
VI. Conclusion
A party denied the right to arbitrate under the FAA has no adequate remedy by appeal and is entitled to mandamus relief.
