About Kathleen (Katie) Mahan, MD

Philosophy of Care

To me it is important to understand the patient's perspective. This will help us to maximize their health goals. In addition, having a child with type 1 diabetes and another who had a liver transplant, I understand how it feels to be a parent navigating through the medical system. I strive make the patient experience as worthwhile and comfortable as possible for parents and their children.

Personal Interests

Spending time with my husband and 4 children, sports, and fitness.

Dr. Mahan does a really nice job of letting me explain how I feel or issues I may be having without jumping in. In my experience she really listens to ensure she gets all information before providing her medical knowledge. It is nice to be heard!

Dr. Mahan is amazing, every visit she is kinda and joyful. She always listens to what we have to say, always patiently and we never felt rushed. Even with our 4 year old boy, she listened to his every word and communicated with him so professionally. We are always excited to see her, and I am genuinely happy to have established such a wonderful relationship with her over so many years. She has postively impacted our lives in many ways with her support and care. I couldn't ask for a better doctor as our PCP. She is the best!
