I’ve been seeing Dr. Maher for two years now, and my appreciation for her continues to grow with each visit. From the very beginning, I heard so many positive things about her—from glowing online reviews to the high praise from everyone at the office—and she has consistently lived up to that reputation and more.
Dr. Maher is the definition of professionalism. She is detail-oriented, an exceptional listener, and shows genuine care and compassion for her patients. What stands out the most is her consistency… no matter how much time passes, her level of care and attention never wavers. That’s how I know she truly cares.
Switching doctors is never easy, especially when you’re managing serious health issues and coming from a place of comfort with someone who’s been on your journey since day one. But with Dr. Maher, that transition felt seamless. Even during my very first appointment, it felt like she had been my doctor for years. She makes you feel at ease, respected, and truly seen—not just as a patient, but as a person.
My last appointment was at the Frederick office, just because I had to switch my usual Tuesday appointment to a Monday. Dr. Maher’s Medical Assistant, Lauren, was great—thorough, friendly, and professional. The entire experience there was smooth and positive.
Thank you, Dr. Maher, for being the incredible doctor and person that you are.

Eden Fernandez provided excellent care during my recent 6-month appointment. She listened carefully to my physical challenges with rheumatoid arthritis and osteoporosis and explained the changes in my conditions. Even more important, she listened to personal family challenges I am facing and their impact on my health. She provided emotional support, care and concern for my situation. She is a very special addition to the practice. Definitely a 5 STAR!
