My 7 year old daughter is a patient of Dr. Volker. He is awesome with children. He is thoughtful, thorough, and accommodating. I truly believe he cares for my daughter and her condition. I never feel rushed in his presence and or forced in making decisions. I do not like the calling policy for his office though. You call one number and they forward a "message" to his office and you wait to hear back. The receptionist in his office are pleasant.
