About Catherine Louise Ash, MD

Care Philosophy My passion for caring for people comes from my family - probably from my mother. She is one of the most caring people that I know and seeing her care for her students in the classroom and seeing her care for her family members around her has just been wonderful. I grew up in that environment of caring and helping out your neighbor.

        I love Dr. Ash and her entire care team! I am always treated with compassion, dignity, and care. I never feel rushed during my visit and am given every opportunity to ask questions and voice any concerns.

        I was a little anxious because I haven't been for a check-up in a while, and after seeing Dr. Ash; I was very relieved and very grateful.
