We love this office. Parents need a place where they can trust the nurses and doctors and this place is definitely that. They are kind, caring, thorough, gentle with the kids, and even work with a lot of insurance companies. My kids love their doctor here and we definitely recommend it!

We often see Dr. Mendoza for my baby's routine check ups and she's amazing! In case she's not available all the other Drs we have seen are amazing as well as the nurses.

I love Dr. Mendoza and Dr. Michelson. Dr. Mendoza has been my daughter's doctor since she was one, she is now 5. She does not rush through visit but takes time. She is always very upbeat, positive and a great listener, I wish I had a doctor that good!.really couldn't ask for a better dr. only thing is she is part time so we don't get to see her most of the time nowadays. have also seen dr Michelson who is also very nice.the only reason I had to change doctors is because we moved and the drive was too far.
