Annual check up for my mom who is in her 90’s. Our family was very impressed with Dr. Maddox’s intelligence and kind manner with Mom, very good at explains things to her and us. With her age we have had several appointments and they are always on schedule. The nurses and front desk are friendly too. We love the location so easy to get to, right off of Coal Creek with easy parking. Nice to find a doctor who is smart and personable, we never feel rushed. We also like that that have an in house lab and Urgent Care Clinic attached for after hours needs.
