I have been going to Dr. O'Mahony for over 15 years and she is the best . Knows her patience and is always available. Her staff is outstanding. They know you by name and will make sure you get the best treatment always. I would be lost if I had chose another doctor.

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.

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!
