Dr. Cliff M. O'Callahan, MD, PhD, FAAP
“Dr. O’callahan is amazing! Very sweet and explains everything clearly and in non-doctor terms for parents to understand. Also always asks if we have any questions. I’ve called a couple times with some medical questions and he had called after hours to put us at ease. Great doctor. BUT as the other reviews say, the wait to talk to someone on the phone can be long. Also they are very over booked and most times I have to see other doctors because o’callahan is always over booked.”
