I have been going to Dr. Ryan for a few years now. She is patient and listens to me and respects my wishes when I choose not to go with the norm. I have recommended her to friends.

Wish she would respect my symptoms I’m experiencing. She didn’t care to assist my issues and cut me off. She prescribed false prescriptions and needs to retire. I don’t appreciate her taking money for office visits. It’s not fair for me to pay 3 office visits for the same situation within 2months. Extremely disrespected and would not recommend her whatsoever!! If you want a lawsuit then have her as your doctor. I will be seeking an attorney about her MD practice
