Dr. Clista is a wonderful pediatrician. I feel confident in his diagnoses and he has a great bedside manner that is lower key but very thorough.

As always, the entire staff was amazing from beginning to end! We really lucked out when we chose you as our son's doctors office! Thanks for all you do! :)

Dr. Clista listened to everything I and my mom had to say. He made phone calls to my old surgeon and asked questions. He is doing everything to find out what is causing my blood pressure problems.

We always have the highest quality care from this provider.

Dr. Clista is very professional, and always provided advice when asked, and does not come off as lecturing a parent on how to do things regarding their child. He respects that all parents and children are different, and some families have different perspectives on how to raise their child. He would speak up if he thought something was not in the child's best interests health wise, but understands that each family may choose to do things a bit differently. That is what I like best about Dr. Clista. He also is very kind and gentle with my kids, and they like him very much.
