What Our Patients Are Saying

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.

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.
