While serving as the Associate Medical Director of a chain of Urgent Care centers in the Greater Boston area, Dr. Boehringer noticed a gap in care for patients seeking HIV prevention, and in response to this she launched one of the first Urgent Care-based PrEP programs in the country, which she ran for several years. Since then, she has turned this program over to other colleagues as she pursued a professional opportunity as Chief Medical Officer of a global humanitarian organization, the position she holds today. This position had her move to the Kansas City area, where she currently resides. Dr. Boehringer is married and has two adult sons, one of whom is pursuing a finance degree and one of whom serves in active duty service with the United States Navy. She and her husband enjoy traveling and are avid scuba divers. They also have more rescue dogs than most people would consider normal.
