Never will I return to Dr. Regan. I was referred to Dr. Regan for abdominal pain a few years back and over the course of multiple appointments, I had three scans done in which he did not suspect anything. I was misdiagnosed with a few different ailments and when the medications I was prescribed and the dairy free diet I was instructed to follow for my so-called "lactose intolerance" did not help, I was told that my pain was "all in my head" and he suggested I talk to a therapist. I am grateful I did not take that as my final answer because months later I was properly diagnosed by a DIFFERENT doctor and finally relieved of my chronic pain.

Dr. Regan is an outstanding Doctor. He goes above and beyond for his patients. My husband and I could not be more satisfied with the care he has given my son. He takes the time to answer all of your questions. He's exceptional.
