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.

        The compassionate support I thought I would clarify. It has nothing to do with my doctor. It was the staff when I called in because I needed to know who the doctor was to fix my compression fracture. I called 3 to 4 times and never got a response. I then sent a not to nice email and someone called me back. However, they still did not have the information I needed.

        Everyone in the office is so friendly & helpful. Dr Ash always explains things to me and listens to what I need to. Very nice appointment.
