They're very good at giving you a chance to agree or not with what could be your best treatment

Dr McMahon has been my primary physician since my diagnosis of HIV. It is bittersweet because the dynamics in the market are forcing me to change facilities based on greed and egos. Dr McMahon is truly a gem in an organization full of many exceptional providers. As an RN for 30 years, I am an educated consumer with high expectations and Dr McMahon and her trainees are caring, direct, knowledgeable on latest trends in research, etc.

Dr. McMahon is an excellent doctor...very professional yet personable! I am very lucky to be in her care!
