He attended the Uniformed Services University of the Health Sciences and graduated in 2004 with an M.D. He completed a pediatric internship at Naval Medical Center Portsmouth in 2005.

He graduated from residency and achieved board certification in Pediatrics in 2010.
From 2010-2013, he served as a staff pediatrician at U.S. Naval Hospital Guam. Despite demanding clinical responsibilities, he performed multiple collateral duties, including Medical Director of the Synagis Program and the Mother-Baby Unit, Chair of the Pharmacy and Therapeutics and Infection Prevention and Control Committees, Joint Medical Attendant Transport Team provider, and Pediatric Advanced Life Support Program Director. His efforts on the Infection Prevention and Control Committee led directly to the awarding of a DOD Patient Safety Award to the command. He was awarded the 2013 Navy Outstanding Young Pediatrician Award for the West Chapter of the Uniformed Services Section of the American Academy of Pediatrics. He also received a second Navy/Marine Corps Commendation medal for his tour in Guam.

He was a member of the faculty of the largest Pediatric residency in the military, and taught medical students and residents in the Pediatric clinic, the newborn nursery, and the Pediatric ward. He led a Medical Home team, and served as acting Service Chief of Primary Care Pediatrics for the last four months of his tour. During this tour, he was recognized as an Associate Master Clinician and was awarded both a Joint Services Achievement Medal and a Joint Services Commendation Medal.
From 2015-2018, Dr. Demitrack served as the Head of the Department of Pediatrics at Naval Hospital Okinawa. In this capacity, he led the largest overseas Pediatric department in the Navy, with 28 subordinates, and maintained its recognition as a Level III Medical Homeport. He also served as chair of the Disease Management Committee. In this capacity, he was responsible for clinical standardization as well as population health quality performance standards such as HEDIS and Oryx. As a direct result of his leadership, the command maintained all HEDIS standards within benchmarks and tied for best in the Navy in Acute Condition and Screening HEDIS measures.
From 2018-2021, Dr. Demitrack served as the Chief Medical Officer of Naval Hospital Pensacola. A senior executive leader responsible for all quality and patient safety programs, he ensured the execution and submission of three process improvement projects that were awarded the Department of Defense High Reliability Organization Award.
