He tries to look at the whole picture before making a decision, which I appreciate! He's not a quick in and out type of guy, he listens and explains well. Very good with kids!!

Very patient with my very active toddler. He was not fazed by his crying and fussiness. That's very important to me not too many children providers show patients surprisingly.

He is excellent. Listens to both patient & parents to make sure they understand the illness & treatment. If you don't understand he explains slowly & in a way that both parties understand. He doesn't rush through the appointment to move on to the next patient.
