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.

        Dr. Ash is a good listener and very compassionate. She takes the time to give great explanations. I feel that she really cares about my health. She's not just going through the motions. She is very thorough. I am very pleased to have her be my primary care physician.

        Dr. Ash and her staff are always helpful, genuine, friendly and accommodating. I trust their care and have referred my wife to their office as well. Dr Ash is very thorough. She takes the time to understand and answer all of my questions, and provides sound guidance and clear next steps.
