What People Say About Dr. Marilyn Ryan, MD
RecentHighestLowestMost Helpful
New patient who found Dr Ryan to be a good listener and informative . She went out of her way to try and obtain test results of a biopsy I had the day before during my visit with her. She followed up promptly with a phone call when the results were available with a plan of action. I had a very positive experience and was glad I did not let the negative reviews I read prevent me from seeing her.

Took me 6 weeks to get an appointment as a new patient - I confirmed the date & time on the phone and typed it into my business calendar while on the phone with the scheduler. The day before the appointment someone from the Doc's office called to confirm the time of which matched my calendar while still on the phone. I showed up on time but was told I had missed my appointment by 3 and half hours. The receptionist was extremely rude and treated me like I was inconveniencing her,

I would never recommend this practice to anyone. The Doctors do not call you back after having testing or even biopsies. They are uncaring and not knowledgeable. Same goes for the office staff cold and uncaring. I was treated like I was just a number. You never get reminders about appointments and when you call for your results it takes days and days and days that is if they even call you back. This was a terrible experience for me. I would never recommend them.

Dr. Ryan is rude. Does she spend the appropriate time with a patient? Yes, but that time is rendered useless when she keeps up blinders preventing her from actually thinking and treating a patient as a person. My mom recently saw her and was treated horribly. Dr. Ryan wouldn't even take the time to look at the ultrasound, because the radiologist report is right here. Apparantly this woman hasn't ever heard of 2nd opinion. We are currently looking for a new endo, waste of time and money.
