"Dr. Van Doorninck has always been so great with our son Max. He had a myofibroblastic tumor but they weren’t able to remove it all, and when he told us that after looking into it more it was seeming to heal itself! I was so thankful! We just had our yearly check up with him and we will go back next year when he turns 5 and then be done with visits!"

"My son was born with an arterial blood clot and were transferred to PSL. We saw both Dr. Clark and Dr. van Doorninck in the NICU and continued care w/ Dr. D once discharged. They both were phenomenal. Personally, I love Dr. van Doorninck. He is so kind, caring, thorough and always took the time to explain everything and answer my many, many questions. Everyone in the office from the highly skilled RNs to the administrative staff are wonderful, too!"

"My son was referred to Dr. Zimbelman and I am incredibly grateful. Dr. Julie Zimbelman spent a surprising amount of quality time with us. She talked with my son and really sought to understand his health concerns. She answered my questions and educated me in a way that felt supportive and constructive. My son adored her. I would recommend Dr. Zimbelman to others who have need of a pediatric hematologist. Her bedside manner is superb and she is incredibly smart. She took care of us, and for that, I give her five stars."

"Dr. Ball and the entire RMHC staff provided excellent care for my son. They have always made us feel like we were important, and that my son's health was their top priority. Their in-depth knowledge and positive attitudes made it possible to get through the most difficult year of my life, and I highly recommend letting them be part of your team."

"Words can’t begin to express my gratitude to this amazing group of professionals. They literally saved our son’s life. We have met every provider in this practice and have nearly daily contact with the office and nursing staff. I have never met such an intelligent, conscientious, honest and most of all compassionate team in my life. They are patient and make the time to connect with us. We have been living out our worst nightmare since our son was diagnosed with cancer, but this team has walked alongside us and we can rest knowing our son is receiving the best care. Thank you for blessing our family!"
