Once he returned home in 2012, he completed his oral and maxillofacial surgery residency at the San Antonio Military Medical Center — a joint army/air force hospital and the only level one trauma center in the Department of Defense. During this time, he served as the chief resident at Memorial Hermann Hospital at the Texas Medical Center in Houston, TX. Known as the busiest trauma center and the largest medical campus in the United States, Dr. Grewal spent the next four years honing his medicine, surgical, cosmetic, and Anesthesia skills.
Upon completing his residency, he served as the Chief of Oral and Maxillofacial Surgery of Kimbrough Army Care Center in Ft. Meade, MD from 2016 – 2020. The highlight of his 13-year active duty career, however, was serving as faculty and attending surgeon at the Walter Reed National Military Medical Center, better known as the President’s Hospital. Dr. Grewal achieved the rank of lieutenant colonel in the United States Army.
