Created and run by Doctor Leslie Thompkins; a renowned medical professional who has dedicated her considerable skills towards helping Gotham's neglected and impoverished population, the clinic is intended for those who are unable to afford government established medical treatment. Unfortunately, the clinic is also used by Gotham's criminals as well as child gang members and drug addicts, however, all of Gotham's Underworld seem to respect the clinic's neutrality.
While the majority of her patients are repeat offenders, Doctor Thompkins attempts to treat each patient with equal compassion and continues to do her job with great perseverance and determination.
As part of his scheme to drug Gotham's East End with Fear Gas, the Scarecrow has set up numerous fans on the clinic's roof.
- Leslie Thompkins served as a psychologist for Selina Kyle during the last month of her six month break from being "Catwoman". Understanding that Selina was reassessing who she was, Batman had recommended Thompkins to Selina to help her work through her personally problems.
- During Gotham's No Man's Land edict, the clinic had grown into becoming a "M.A.S.H. Sector" open for any of Gotham's remaining citizens as the city's only remaining medical establishment. As such the sector held a strict 'No Violence' policy regardless of her patients's actions and intent and was guarded heavily by the Bat Family.
- During Gotham's Gang War the clinic again became a M.A.S.H. building, however, the Ghost Dragons gang attempted to take over the clinic by force and was stopped by Batgirl.
