A third generation Californian, I am a product of a family of small town country doctors. I have been practicing dentistry in Southern California for more than 30 years. I warmly invite you to visit our practice, and experience what we think is a special office.

Introducing Dr. Daniel Balaze! Educated at the Pankey Institute, he is certainly one of the best dentists in Orange County.

Dr. Dan joins our practice from Cleveland, Ohio.  I have known his father, Brian, for over 20 years and am thrilled to welcome him to our team. He has completed the curriculum at the Pankey Institute, earned his fellowship in the Academy of General Dentistry, and shown himself to be a perfect compliment to our office.
