Dr Demirci has been very responsive via MyChart whenever we have a question. He was very thorough in our appointment. We didn't feel rushed at all. He made sure all our questions were answered and we understood the plan of care. We also appreciate that he communicated with our pediatrician and helped to limit blood draws by bundling orders.
