Anesthesiology & Pain Medicine
Thomas M. Larkin, MD
Pain Management Institute
Dr. Thomas M. Larkin is an anesthesiologist and interventional pain physician at the Pain Management Institute on Rockledge Drive in Bethesda. He is board certified in pain medicine by the American Board of Anesthesiology and holds a faculty appointment as Assistant Professor of Anesthesiology at the Uniformed Services University of the Health Sciences.
Background and training
Dr. Larkin received his medical degree from SUNY Upstate Medical University in 1991 and completed his internship, anesthesiology residency, and pain management fellowship at Walter Reed Army Medical Center, finishing his fellowship in 2000. He stayed on staff for another seven years, serving as Chief of the Pain Clinic at both Walter Reed and Landstuhl Regional Medical Center in Germany — the primary receiving hospital for casualties evacuated from Iraq and Afghanistan. He left the Army as a Lieutenant Colonel to enter private practice.
Why patients choose Dr. Larkin
Military pain medicine is a demanding apprenticeship: high volumes of blast, spine, and nerve injury in patients who are young, otherwise healthy, and expected to recover function rather than simply feel less pain. Dr. Larkin brought that background into private practice, and has since become one of the first four physicians in the United States to pass board certification with the American Board of Interventional Headache Medicine — a credential that matters for patients whose headaches have not responded to standard neurology care.
Practice focus
Chronic spine and nerve pain, interventional pain procedures, headache and facial pain, and neuromodulation.
