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.

This place does ask for reviews which is why I am doing one, I wouldn’t be doing a review if the service I received was bad. This has been one of the best doctors I’ve visited in a long time. I don’t think they are a specialist by any means but the doctor did really try to help me and I really appreciate that. They did thorough labs and did their best to identify anything wrong with me. Their staff are all very calm and friendly. The practice is very religious forward but they are not a church and do not try to preach their values to you so please don’t let this discourage you. I will highly recommend Dr Armstrong to anyone I know as they are a very caring practice and truly listened to my problems. Not to mention their staff went over and above with referrals and helping me out. Thanks so much to the team at heart of Mary’s.
