Dr Hart was experienced, knowledgeable and thorough. She has a plan with health checkups to monitor any changes in my health status. Easy to book. Easy to contact.

I highly recommend Immaculate Heart of Mary Family Medicine. From the moment I walked in the door I was treated with dignity and respect. You just get a sense that everyone there really cares about you. Dr. Hart never made me feel rushed and I felt she was really listening to me. I’m so happy I finally found a doctor that I can trust completely.
