Mary Margaret Oneil

Worst experience I’ve EVER HAD they were rude and just out right awful. I will tell everyone that it’s a mistake to go there

Never actually seen her. Front staff is very rude. When I went to go and thought I was seeing her I saw someone else. NP ordered blood work, didn't order the right blood work. Asled how the medication I was on was doing, I was never prescribed anything. As a young female who suffers from chronic undiagnosed pain as well as joint and muscle pain I want relief so I can function as a normal young adult. Bo diagnosis. Will not be returning.

Dr Oneil and all of her nurses and the rest of the crew are great, would highly recommend.

I have seen Dr. O'Neil since she began practicing in WNY. She also treated my husband and incidentally found what ended up being a cancerous tumor on his kidney. He unfortunately passed away because the cancer had spread. Dr. O'Neil has always been kind, professional, and helpful with my health problems. I would recommend her highly. On my last visit, apparently there was a mistake and I waited 1&1\2 hours in the patient room. I left in anger without talking to her. I will reschedule.

This was the first rheumatology office where the clinicians actually took the time to provide true patient-centered care. Sarah, the PA was amazing. She was kind, attentive, and thoughtful. Dr. Oneil is also an excellent clinician, who took the time to collaborate on a plan with me - a plan that I felt comfortable with and that met my needs and preferences for treatment. The receptionist and the waiting room were very pleasant and the waiting time was much shorter than I expected. Highly recommended.

She is a caring doctor who listens to her patients and is very knowledgeable in the arthritis field. Have been her patient for 12 years and came with her when she opened her own practice. I have confidence in her treatment.
