Trusted, Proven

Dr. Margaret Hart and her staff were terrific. She was patient, understanding, took the time to answer my concerns, and was very knowledgeable. If it was not for the fact that she was a DOCTOR, I know that she would be the PERFECT FIRST GRADE TEACHER, that any parent would trust, as she was very patient, friendly, and outgoing.She understood my issues, was willing to listen. Her staff was very friendly and approachable. Her office is willing to do medical testing and blood draws through SONORA QUEST LABS, which fits in well with my other doctor specialists, who also use SONORA. So, I will never again have to deal with any primary care doctors, who draw my blood ... but don't wish to give me any results. Dr. Hart is a great find, and I hope she does not retire for a long time.

I don’t know what this yelp thing is all about,  but I do know now about Dr. Hart of IHM Family Health Center.  She definitely gets FIVE THUMBS UP from me for her medical knowledge, care, and the willingness to communicate with a patient and answer my questions, concerns, and medications.  I have a very rare orphan disease, that involves having many Medical Specialists.I have had three appointments with Dr. Hart so far, since my first June 30, 2023 appointment with her.  I am so please to have Dr. Hart as my replacement PCP doctor.  She knows how to communicate with her patients, answer my questions, and carry on an exchange about the over 5000 MGs of meds, that I am required to take daily to stay in REMISSION.   So if you need a good doctor, WHO LISTENS, go try her out.

Everyone was kind, compassionate, and professional. I did not have to wait for assistance, and everyone acknowleged me. Dr. Hart, Jessica, and Darda are amazing people, and I thank the Lord for them!

I had three visits already with the first on 6-30-2023 with Dr. Hart. She and her staff were very pleasant and well organized. Dr. Hart was very knowledgeable and willing to answer all my questions, concerns, and medications, despite my having a very rare, orphan disease. Dr. Hart was willing to make the effort to solidly communicate with me, as a patient. So, I felt a great relief in finding my new replacement PCP physician, that was as professional, as my specialists. She was also able to refer me to another specialist, in order to deal with one of my other concerns. So Dr. Hart and her friendly staff get a big FIVE THUMBS UP from me.
