Donna Randall, MD

Medical Director

Dr. Randall provides mental health and addiction medication management to our clients, including Suboxone. 
Those who have known Dr. Randall as a physician and friend are truly fortunate. She is a powerhouse. Not just physically, which is true, but as a woman who radiates inner strength.
Dr. Randall's professional life began in classical music. After completing her undergrad and a Master's, she was teaching music on the college level when she was inspired to become a physician. With that strength of will that's evident in all she does, she completed the science courses she needed to get accepted into medical school.
Dr. Randall began her medical career in family medicine. When selecting a specialty, she chose to become an OBGYN for a number of reasons. First, the complexity of the specialty made it endlessly interesting. Second, she loved the arc of care that she could provide – from teen years, through pregnancy, delivery, and motherhood and on to the mature years in a woman's life. Dr. Randall has two decades worth of experience treating a variety of physical and mental health conditions across the lifespan.
