We could not be happier with the care we have received @ Sea View Pediatrics. Dr. Gaitan was highly recommended by a friend and we are very happy with him. He is very easy to talk to, down-to-earth, and super responsive to any concerns that come up with my son.

Jennifer J., Mission Viejo, CA

Still 5 stars here! My daughter sees both Dr. Natori and Dr. Johnson and I have nothing but good things to say about both of them. I work right above them and I always hear patients parents saying how great they are too! I love this office and wouldn’t ever change!

Alexis E., Laguna Hills, CA

I am very happy with Sea View. My daughter will be two in March and we have been seeing Dr. Natori since birth. Dr. Natori has always been very pleasantly professional. I love the nursing staff, and have found the office staff to be nothing but accommodating.
