Doctor Mandelik has always been the best however we had seen doctor Field one time then doctor Mandelik after. Doctor field insisted we still needed to be seen again even though we had already followed up with doctor Mandelik which made the appointment that resulted in this survey unnecessary.

The doctor was not our normal doctor but he was so kind and caring.

Dr Mandelik is always prompt and thorough during our well child visits. I never feel uncomfortable asking questions. I love that he's attentive, knowledgeable, and discusses evidence based care but not quick to jump to interventions which aligns with what we want in a pediatrician. We've been so happy with his care for both of our boys.

Was my pediatrician for 21 years & im so happy that I can also have my son be a patient of Dr. Mandelik's. He is an amazing doctor & really cares & listens to the parents concerns about their children's health & well being
