My father was a physician and I frequently evaluate care by providers in my own mind during contacts. Dr. M.A. Riley is excellent in all the ways that matter to me.

I had a wonderful experience with my PCP, Dr. Riley. She consistently includes me in my care decisions, ensuring I fully understand my care plan and feel empowered to make informed choices. Dr. Riley is always friendly, courteous, and treats me with the utmost respect. Her ability to explain complex medical information in a way that is clear and approachable is truly exceptional. I would highly recommend Dr. Riley and this office to anyone seeking compassionate, patient-centered care.

I like Fr Riley. She listens, assesses my problem individually; and most of all, is not a pill pusher.
- 5 out of 5 starsReviewed on 5/14/2024
I LOVE Dr. Riley. Unlike the majority of doctors, she actually LISTENS to her patient's concerns, and she doesn't just want to throw a bunch of pills at you to treat your symptoms. She actively wants to help get to the root of your issue/s so that it/they can be treated correctly and effectively. I suspect a large part of this is the fact that she is a DO rather than an MD. Every DO I've ever been a patient of has been far superior to all of the MDs that I've been a patient of.

A VERY POSITIVE EXPERIENCE

Dr. MaryAnn Riley is the best. I am very happy with her and feel confident in her as my doctor.
- 4 out of 5 starsReviewed on 1/2/2024
Although I had seen this doctor at least 2-3 times before, she was confused about a medical condition I have (thinking it was hypo instead of hyper) and who was prescribing my medication. It didn't appear that she had looked at my medical record before our appointment. In our three visits thus far, the only physical exam she provides Is to listen to my heart and lungs (as I'm thankfully healthy!). I'm considering whether to see her again or ask to switch to another provider.
