Dr Dresing is my EP doctor and Dr Menon is my Cardiologist at CC. I live five hours from the clinic. Dr Dresing accommodates me by taking time between his scheduled cases to see me Tuesdays each year which Is Dr Menon's only office day. This saves a ten hour round trip for a separate annual EP appointment.
