Visit our pediatric office

Pediatric Associates offers a warm, kid-friendly environment designed to ease anxiety and make every visit comfortable for both children and parents.

Behavioral health

About 3 times more boys than girls are diagnosed with ADHD. See how our pediatrician can determine a treatment plan to help your child lead a happy and healthy life.

Virtual visits

Not every health concern needs a trip to the doctor’s office. With the KidzDocNow app, your child can see a pediatrician with a video appointment right from the comfort of home.

After hours & weekend visits

We’re here for the sniffles, fevers, and “uh-oh” moments—even on evenings and weekends.

He is also a good educator, explaining concepts clearly.

Dr. Cortes is a very caring pediatrician who is truly committed to doing what’s best for children, while working with the parents and allowing them to make informed decisions. He is also a good educator, explaining concepts clearly, giving the parents knowledge about issues at hand. He is a good listener, and always willing to answer questions. He has been a wonderful pediatrician for my daughter for the past 16 years, and we gladly drive two hours to go see him.
