Dr McMahon is the best doctor I have ever seen. I had to leave because of the office staff. He seemed frustrated with them as well. But again, he is the most comprehensive, knowledgeable, and compassionate doctor I have ever seen or worked with at the hospital.

His office staff are incompetent. Dr. McMahon you haven't responded to my letter. Kathy is a liar. Go to a better doctor's office. Save yourself the trouble that I have endured.

Horrible doctor's office. Staff is unprofessional, non-caring, and they set a very low bar for health care. Why deal with this staff? Go somewhere else and at least get better customer and health care.

Amazing doctor. He really worked with us in our out of state hospitalization and helped make things go so smoothly. He really also helped us understand what to do to manage the condition in the future.

Never can get though to a person and when you do leave a message they may call you back, takes weeks to get prescription refilled, Dr McMahon is great just not his staff
