Under Dr Kassar care is gotten my A1c down from a 14.9 to a 5.6 Dr Kassar doesn’t operate as your doctor telling you what to do. He operates as a partner in your healthcare. I think he’s an an amazing individual and that I got lucShow moreky to find him. I like that he talks to me and not at me makes it much easier to listen and follow directions.

We had our visit with Makayla, Dr. Kassar’s nurse today. She explained the new Libre 3 blood sugar monitor & placed the first one. She was knowledgeable, kind & empathetic!
