Dr O'Mahony is very professional yet warm and caring. She listens to your concerns.

I have Dr. O'Mahony as my primary doctor. I called to get an appointment but because I had not seen her in multiple years was told that I am considered as a "New Patient" and could not see her until September. When I ask the receptionist if I could see her sooner because of symptoms I was having she rudely told me to see who I was seeing for the last years. Since I had not seen any other doctor she then said go to a express care center because they would not see me till September.

Dr. O'Mahoney is the most caring doctor I've ever had. She actually listened to me and recognized the symptoms of a rare disease that she noticed on the spot. It had been misdiagnosed for years. She quickly referred me to a specialist and I'm on the right track now.I would highly recommend her!
