Harbor Pediatrics Medical Group

Harbor Pediatrics is a Primary Care Pediatric facility located in Newport Beach, California. We have been providing care to the children of Orange County since 1954. We provide general pediatrics services including newborn and infant care, childhood well physicals and immunizations, behavioral consultations and same day sick services.

Our doctors are members of staff at Hoag Memorial Hospital Presbyterian, as well as maintain an excellent partnership with Children’s Hospital of Orange County (CHOC) providing our patients with superior inpatient care and urgent care services when it’s needed.

The goal of Harbor Pediatrics is to work with parent and child to achieve the best health possible. We accomplish this through parental guidance, teaching of safe and healthy lifestyles, preventive medicine, screening/early detection of illness and other problems, to help ensure that each child will grow and develop to their optimum potential.

We take pride and value the relationships with our families. We appreciate the trust that our families place in us, for multiple generations and feel privileged to be a part of their children’s lives.

  • I went to Harbor Pediatrics as a child and now I am taking our own Kids here. Great team of doctors. They are dedicated, experienced and knowledgeable.

  • We see Dr. Mendoza for our 4 and 2 yr old.  She is sweet and both boys adore her!  The staff is accomodating and makes a trip to the dr not so fearful!  We never feel rushed with our time, and our questions are always answered promptly.  The staff do their best to make sure all forms are in order, and we never had insurance issues that could not be handled by a quick phone call. I would highly recommend Harber Peds!

  • My son and I both love this office. My son is now 2.5 and has been seeing Dr. Chen since his 1 year check-up. Dr. Eugene Chen has amazing bedside manner- he's thoughtful, funny, and very gentle. He never seems to be rushing and will answer questions, offer advice, and explain procedures/ medications very thoroughly. The nurses are also great! We are always greeted with a smile and they all seem to genuinely love children. Even though my son has received numerous vaccines, been seen for numerous colds, ear infections and the like, he is still excited when he pull up to the office: "It's the fish and truck house!!" They have a fish tank and train table with plenty of trucks and trains.

  • We see Dr. Michelis and love him. We've seen him since birth- and he is absolutely great with our almost 2yr old son. We've had a "sick" visit w/Dr. Chen also and liked him a lot. We originally signed up with Dr. Mendoza who was equally wonderful- but since Dr. M was on duty when my son was born- we've just stuck with him. The front desk is friendly and there is never a wait!

  • Love this pediatric office. Great doctors and awesome staff. No matter our problem they've been so helpful and accommodating. Love the office phone nurse too... She's a great help when we don't know what to do sometimes. There's more than one doctor, we have always been able to get in... Even in a last minute panic. Office is clean and there's a well room, sick room and rash room. Parking is easy and plentiful.

  • This is THE BEST pediatric office around. No matter what is going on they will always get me in for an appointment, even on a Monday at 4:45 to get an object out of my kid's nose. True story. I would highly recommend this office to any mom or dad in Orange County. I love all of the doctors in this office!
