I loved my previous (retired) rheumatologist, but have found that Dr. Maher is an outstanding replacement. She tries to accommodate my often crazy scheduling needs and listens and responds to my questions and concerns.

Dr Maher has been taking care of me for a few years now and it’s been quite tricky because of my history and symptoms. She hasn’t given up and she is leaving no stone unturned. She listens, she cares and she is so smart yet down to earth. I would recommend her to anyone and I have recommended her to people needing her speciality.

Always a wonderful experience! Dr. Maher is personable and professional! She takes the time to listen to my concern and questions; she takes the time to address and explain those questions in a way that I can understand. Never appears rushed or bothered although I know she must certainly be busy! Cannot thank her enough for care and interest!

Great listener. Very thorough discussion of everything related to my care with her.

Dr. Maher should have been a pediatrician. Superb doctor, excellent diagnoses, sense of humour, very warm and caring physician. Her medical practice is very fortunate enough to have included her. Dr. Maher is so top notch, I think she gave me rheumatic fever. Six stars for Dr. Maher. Don't go to anyone else.

I'm a combat veteran with PTSD. Medical environments are my primary trigger, which means I walk into most appointments already managing a physiological response before anyone's even called my name. I say that not for sympathy, but because it's the baseline against which I'm measuring what happened at this practice. I arrived early for my first appointment. They took me back 15 minutes before my scheduled time, completed my vitals, and started my medical history before the clock even started. That's not how medical offices operate, but this one does. Every person I encountered, from the receptionist to the medical assistant who walked me back and took my vitals, to the X-ray technologist, to Dr. Maher herself, was genuinely warm, calm, and respectful. Not scripted. Actually calm. That kind of consistency across an entire staff has to come from the top. Dr. Maher wasn't rushed, and it showed. She ordered a comprehensive imaging workup across hands, feet, knees, hips, and lower back, along with a full diagnostic lab panel, and she walked me through every X-ray image personally, explaining what we were actually looking at rather than just telling me everything was fine. She matched my vocabulary, never dumbed things down, and clearly knows her field. When I went to radiology, she asked if I was okay in a dark room, because she understood why that question mattered. She also offered a lab slip so I could leave after imaging rather than wait, understanding without being asked that waiting isn't a neutral experience for everyone. I left that appointment having been heard, seen, and treated with genuine dignity. I've never been able to say that about a medical appointment before.
