Concierge Medicine On the Most Personal Level
In 2008, Radley Griffin, M.D., founded Griffin Concierge Medical on the idea that medical care could be better. His father, a trusted pharmacist, instilled in Dr. Griffin and his five brothers the notion of slow medicine, where relationships matter, and knowledge is power. This propelled Dr. Griffin to establish a practice where empowering patients to make decisions about their own healthcare is the foundation for exceptional care.
Our concierge doctors are passionate about helping you live well. We take the time to get to know you on the deepest personal level to provide medical care that is as individual as you. We are focused on prevention and optimization, helping you identify risk factors early so you can make changes that can impact your quality of life. We are problem solvers. We use the latest innovative diagnostics to understand your health concerns and help you set personal healthcare goals. Our partnership is entirely collaborative, and you are a main player in the decisions that affect your health and well-being.
