Dr. Sim is wonderful! He takes the time to listen and explains everything. Dr.Sim took care of me in the nursing home and now he takes care of me now that I'm home. Dr. Sim makes sure I get all of my meds in a timely manner aShow morend he makes sure they don't interfere with each other. I care for him not only as a physician but as a friend. The staff is also wonderful too. I had Dr. Biondo for many years but he had surgery and needed to cut back on patients. I really care about him too. Thank you!
