Dr. Theresa Day is a fellowship-trained, board-certified family medicine specialist. Dr. Day completed a geriatric medicine fellowship at the University of Arizona in 2022, following her family medicine residency at UCSF Fresno. She earned her medical degree from the University of Arizona College of Medicine in Tucson, AZ. Before joining our center, Dr. Day worked as a locum tenens physician at an FQHC clinic in Visalia, California. Her career took an exciting turn when she and her husband welcomed twins into their lives, leading her to dedicate herself to being a full-time mom. In 2021, her passion for senior care brought her back to medicine, and she pursued a fellowship in geriatrics. During this time, Dr. Day gained valuable experience at the Tucson VA Hospital, Banner University Medical Center, and Quiburi Nursing Home in Benson, AZ. Dr. Day takes pride in her family's resilience and kindness, particularly as a veteran's wife. Beyond her medical profession, Dr. Day finds joy in spending time on the farms where her husband serves as the assistant farm manager for Alvin School District.
