the nurses and Dr. Liza Melendez were exceptional.

My kids had their annual appointment for a checkup. The nurses and Dr. Liza Melendez were exceptional. My teenage daughter was cared for as if she was the doctors child with questions being ask of how she was doing in school and the puberty changes she was experiencing. We were there for about an hour but my kids got all of their shots updated and the required forms for entry to school next year. We had a very pleasant experience and we recommend Pediatric associates to anyone.
