Herbert Brown, a prisoner, claims that his custodians’ failure to provide adequate medical care amounted to “cruel and unusual punishment” in violation of the Eighth Amendment. He sued the District of Columbia (“District”) and the Corrections Corporation of America (“CCA”), along with former Attorney General John Ashcroft, 1 three high-ranking District officials including the mayor, and several District and CCA employees in their individual capacities.
The district court dismissed Brown’s complaint against the District, CCA, and the District officials for failure to state a claim. We affirm these dismissals in all respects but two. We reverse the dismissal of Brown’s claim against the District for the violation of his rights while in the District’s prison in Lorton, Virginia. The district court also dismissed Brown’s complaint against the District emрloyees and the CCA employees because Brown failed to serve them. We reverse this dismissal, too. Our reasons follow.
I.
A.
Brown’s complaint alleges a spate of harms, which we must take as true when reviewing the dismissal of his claims.

Erickson v. Pardus,
— U.S.-,
Finally, a Dr. Rafford diagnosed Brown with gallstones and ordered his immediate transfer to D.C. General Hospital for treatment. For the next sixty days prison officials failed to make the transfer while Brown continued to complain of intense pain. Not until Dr. Rafford saw Brown a second time, made the sаme diagnosis, and again ordered his immediate transfer did prison officials finally comply. At the hospital, Brown underwent surgery that removed eighteen gallstones blocking his urinary tract. After he returned to the Lorton prison, Brown continued to complain of similar symptoms. Over the next several months, the prison’s medical staff again refused to treat him or wrongly diagnosed his conditiоn. In one instance, a medical assistant diagnosed food poisoning and ordered Brown’s transfer to a hospital, but prison officials again refused.
In 1997 the District transferred Brown to the Northeast Ohio Correctional Center, *1282 a private prison owned and operated by CCA in Youngstown, Ohio that houses inmates for the Federal Bureau of Prisons. There, Brown’s experience with inadequate medical care continued. In one instance, a Dr. Mazzi prescribed diabetes medication for Brown without ever examining him. After months of suffering from the medication’s ill effects, Brown learned that he did not have the disease. At both the Virginia and Ohio facilities, Brown filed numerous grievances informing prison officials and the District of his plight.
B.
In December 2004 Brown filed suit in the United States District Court for the District of Columbia under 42 U.S.C. § 1983, which creates a cause of action against state and local officials for violations of federal rights. The statute reads:
Every person who, under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory or the District of Columbia, subjects, or causes to be subjeсted, any citizen of the United States ... to the deprivation of any rights, privileges, or immunities secured by the Constitution and laws, shall be liable to the party injured.
42 U.S.C. § 1983. Brown claimed that the District, CCA, and several individuals denied him adequate medical care in violation of the Eighth Amendment. The individual defendants 4 he sought to hold personally liable include three District officials (Odie Washington, Direсtor of the D.C. Department of Corrections; Elwood York, Director of External Confinement in the D.C. Department of Corrections; and Anthony Williams, former mayor of the District of Columbia); six doctors at the Lorton prison (Taylor, Marzban, K.R. Sorem, Ferry, Park, and Easted); and nine employees 5 at CCA’s Ohio prison (Mazzi, Willis Gibson, A. Warfield, R. Adams, M. Perryman, A. Sims, J. Bass, B. Goodrich, and J. Ceri-mele). He served the District and defendants Williams, Washington, and York, but failed to serve the remaining individuals. Although CCA accepted service, it never appeared in district court. The District, along with defendants Williams, Washington, and York, filed a motion to dismiss.
On August 1, 2005 the district court dismissed Brown’s action in its entirety. Brown v. District of Columbia, No. 04-2195 (D.D.C. Aug. 2, 2005). The court concluded that Brown failed to state a claim against either the District or CCA because his treatment at the hands of various prison doctors did not violate the Eighth Amendment: “Although there may have been delays in rendering treatment, displeasure as to the quality of treatment, or disagreement about the course of treatment, the plaintiffs complaint makes clear that indeed he received treatment. Negligence does not rise to the level of dеliberate indifference to a prisoner’s serious medical needs.” Id. at *5. The court also reasoned that even if Brown had stated an Eighth Amendment violation, he failed to make allegations which, if true, would hold the District liable. His claim against the District, at best, was based on a theory of respondeat superior, insufficient under well-established precedent. Id. at *6-7. In addition, the court dismissed the claims against defendants Williams, Washington, and York because Brown failed to allege that these public officials were personally involved in the decisions adversely affecting Brown’s rights. Id. at *7. Finally, the court dismissed sua sponte the claims against the CCA and District employees *1283 because Brown did not serve them. Id. at *4.
Brown appeals the decision in all respects. The district court exercised jurisdiction over this case pursuant to 28 U.S.C. § 1331, and we have jurisdiction under 28 U.S.C. § 1291. Our review is
de novo. Browning v. Clinton,
II.
Brown argues that the district court erred in dismissing his claims against the District for alleged failures of medical care. We agree.
A.
A municipality is a “person” subject to suit under 42 U.S.C. § 1983, although its liability is limited.
Monell v. Dep’t of Soc. Servs. of City of N.Y.,
Brown’s complaint alleges a violation of the Eighth Amendment’s prohibition against “cruel and unusual punishments.” U.S. CONST. amend. VIII. The Supreme Court has placed within the ambit of this prohibition “punishments ... which involve the unnecessary and wanton infliction of pain.”
Estelle v. Gamble,
The court must next determine whether the plaintiff has alleged facts sufficient to hold the municipality liable. Under
Monell,
“a local government may not be sued under § 1983 for an injury inflicted by its employees or agents. Instead, it is when execution of a government’s policy or custom ... inflicts the injury that the government as an entity is resрonsible under § 1983.”
B.
Applying the
Monell
analysis, we conclude that Brown’s allegations state a claim that the District violated his Eighth Amendment rights at the Lorton prison. Although the task of discerning what constitutes a “serious medical need” under
Estelle
may prove vexing at the margins, Brown’s claim givеs us no pause. His jeremiad reaches a climax in recounting his experience with gallstones. The intense and often relentless pain that accompanies this condition, and the complications that can follow, easily push Brown’s claim into the category of serious medical needs.
See, e.g., Toombs v. Bell,
Furthermore, Brown claims that prison officials demonstrated “deliberate indifference” to his condition. Although Dr. Raf-ford diagnosed Brown with gallstones and “ordered [him] to be immediately transferred to the D.C. Generаl Hospital for treatment,” Compl. ¶ 17, he “was never transferred ... and continued to report to the infirmary with complaints of Pain and stomach sickness for an additional (60) sixty days,” id. ¶ 21. Brown also alleges that “the defendants subjected [him] to an Unnecessary and wanton infliction of pain out of deliberate indifference ... to his serious medical needs.” Id. ¶ 38. The government’s attempt to style Brown’s claim as mere griping about the quality or course of treatment misstates the gravamen of the allegation. After Dr. Rafford notified prison officials of Brown’s need for immediate hospitalization, they failed to transfer him for sixty days while he continued to suffer from gallstones. Presented with these claims, we do not hesitate to conclude that Brown alleges an Eighth Amendment violation.
Brown also avers facts sufficient to hold the District liable under
Monell
because he alleges that the District failed to act even though it “knew or should have known of the risk of constitutional violations.”
Baker,
*1285 Brown should have the chance to prove the case he has sufficiently pled. We therefore reverse the district court’s dismissal of Brown’s claim against the District for the аlleged Eighth Amendment violations that occurred while he was incarcerated at the Lorton facility. 7 We also affirm the district court’s dismissal of Brown’s claim that the District is liable for the alleged harms committed by CCA because, as we explain in Section IV, his claim against CCA is barred by res judica-ta.
III.
Brown also claims that Washington, York, and former Mayor Williams are personally liable for the Eighth Amеndment violations that occurred from 1995-1997 while he was at the Lorton facility and before he was transferred sometime in 1997 to the CCA facility in Youngstown, Ohio. We affirm the district court’s dismissal of these claims.
We take judicial notice of the fact that Williams did not begin his first term of office as mayor until 1999 and Washington received his appointment as Director of the D.C. Department of Corrections that same year,
see
Res. 18-138, Dir. of the Dep’t of Corr. Odie Washington Confirmation Resolution of 1999, 46 D.C. Reg. 5517 (June 8, 1999), and accordingly affirm dismissal of the claims against them.
See
Fed.R.Evid. 201. Brown also fails to state a claim against York. Under the theory of supervisory liability that Brown asserts, the plaintiff must allege that the official “was responsible for supervising the wrongdoer.”
Haynesworth v. Miller,
IV.
Brown also argues on appeal that the district court erred when it dismissed his claim against CCA for alleged violations that occurred while he was a prisoner аt the Northeast Ohio Correctional Facility. These allegations resemble those he makes against the District for failure to provide medical care. We affirm the district court’s dismissal of this claim, although we do so on the ground of res judicata, an argument CCA makes for the first time on appeal.
CCA argues that Brown is attempting to re-litigate an issue on appeal already decided by a federal court in
Brown v. CCA,
No. 03-822 (N.D.Ohio 2003). Before we address CCA’s argument, we must first decide whether CCA, which did not appear before the district court in this matter even though it was properly served, can raise the affirmative defense of
res judicata
for the first time on appeal. Typically a defendant must plead the defense in the answer to the complaint.
Poulin v. Bowen,
These factors are all present here. In Stanton, the defendant retained the right to argue res judicata because the district court ruled on a dispositive motion before the defendant had answered the complaint, leaving him free to assert the defense on remand. Id. Likewise, CCA has not forfeited the right to raise the defense here. Although CCA risked entry of a default judgment on account of its absence, it did not thereby forfeit the right to answer Brown’s complaint and raise the defense if the district court’s dismissal in its favor was later reversed. Moreover, the relevant facts are uncontroverted. Neither Brown nor the appointed amicus curiae identifies any factual disputes that arise in connection with Brown’s earlier lawsuit. Finally, not to consider the defense now would only engender delay because CCA would be free to raise it on remand.
Therefore, we properly consider the res judicata defense for the first time on appeal and hold that it bars Brown’s claims against CCA. In the previous case, Brown brought the identical claim against CCA that he brings now: Dr. Mazzi prescribed diabetic medication for Brown when in fact Brown did not have diabetes. Brown v. CCA, No. 03-822, at *1 (N.D.Ohio 2003). The court dismissed that case because the governing statute of limitations barred the action. Id. at *2. Brown does not dispute that res judicata would bar his claim against CCA for the actions of Dr. Mazzi. But Brown argues that he has raised a separate claim against CCA that its mediсal staff acted with deliberate indifference in failing to diagnose his hepatitis while he was incarcerated at the CCA facility. We find no such claim. Nowhere in his complaint or other pleadings does Brown allege that medical personnel working at CCA, other than Dr. Mazzi, refused to diagnose him or otherwise showed deliberate indifference to his serious medicаl need. Brown’s claim against CCA for the conduct of Dr. Mazzi is barred by res judicata and Brown otherwise fails to state a claim for relief against CCA.
y.
Finally, Brown contends that the district court erred in dismissing for lack of proper service his claims against the six District and nine CCA employees, all of whom Brown sued in their individual capacities. We agree.
Rule 4(m) of the Federal Rules of Civil Procedurе requires the court to give the plaintiff notice prior to dismissal for lack of service:
If service of the summons and complaint is not made upon a defendant within 120 days after the filing of the complaint, the court, upon motion or on its own initiative after notice to the plaintiff, shall dismiss the action without prejudice as to that defendant or direct that service be effected within a speсific time; provided that if the plaintiff shows good cause for the failure, the court shall extend the time for service for an appropriate period.
Fed.R.Civ.P. 4(m) (emphasis added). Interpreting a predecessor of Rule 4(m), this court held that a district court errs when it dismisses a suit for failure to effect service and the plaintiff is “neither actually nor constructively on notice as to the impending
sua sponte
dismissal.”
Smith-Bey v. Cripe,
VI.
We affirm the dismissal of the claims against CCA, the District for alleged violations committed by CCA, and the high-ranking District officials. We reverse the dismissal of the claims against the District for alleged violations at the Lorton facility and the dismissal of the claims against the nine CCA and six District employees for failure to serve, and remand to the district court for further proceedings consistent with this opinion.
So ordered.
Notes
. Because a panel of this court has summarily affirmed the district court’s dismissal of Brown’s claim agаinst the former Attorney General, Brown v. District of Columbia, No. 05-5320 (D.C.Cir. May 23, 2006), we do not discuss Brown’s claims against Ashcroft.
. Brown filed pro se in district court. On appeal he submitted a pro se brief and also joined the brief of appointed amicus curiae. All quotations from Brown’s filings are reproduced verbatim.
.The record is devoid of any information regarding the nature of Brown’s crime or the terms of his sentence, neither of which is relevant to our disposition of his apрeal.
. We use the defendants’ names as Brown used them in his complaint.
. CCA disputes whether these individuals are employees, but we need not reach this issue.
. Aside from his general claim that "all grievances [have] been exhausted,” Compl. ¶ 42, Brown does not expressly state that he informed District officials of his condition during the sixty days after Dr. Rafford first ordered his transfer to the hospital and before prison officials complied with the order. However, construing the plaintiffs complaint liberally as we are required to do on a motion to dismiss and mindful of the Court’s instruction to hold a
pro
se complaint to "less stringent standards,”
Erickson,
. The complaint alleges several instances in which the District failed to provide Brown mеdical care at the Lorton facility, which Brown may or may not have intended as separate claims. The district court did not identify distinct claims and neither do we. On remand the court may consider whether Brown raises one or more claims separate from the gallstones claim and then determine in each instance whether Brown states a claim for relief.
