Our Story & Mission

OC Perio & Implants Dental Group has been a trusted leader in periodontal and implant dentistry since 1976. As the first periodontal practice to open in Mission Viejo, we have proudly served the South Orange County community for nearly 40 years. Dr. Robert Hirst founded our practice after his service in the US Navy Dental Corps. Dr. Ajay Setya joined Dr. Hirst and took ownership of the practice in 1997. Together with Dr. Christen Bergman and Dr. Moe Reshad, they now provide expert, comprehensive periodontal services to the residents of South Orange County.

Our mission is clear: to deliver uncompromising quality while fostering authentic relationships built on trust and transparency. Exceptional dental treatment should address the complete person, not merely isolated symptoms. Our commitment to excellence, advanced technology, and compassionate patient care distinguishes us.

State-of-the-art Technology

Our doctors use cutting-edge technology to ensure the best possible results and to make your treatments more efficient, comfortable and minimally invasive.

Our digital X-rays are clearer, faster to produce and emit far less radiation than standard film X-rays. Our cone beam 3D CT scanner produces 3D images of your entire jaw bone and all your teeth. With these images loaded into special software, Dr. Reshad can precisely plan your implant placements and any needed bone grafting ahead of time. This makes the procedure very accurate and minimally invasive.

Our dental laser and micro-instruments are much less invasive and more precise than standard surgical instruments and are used when needed in our gum disease treatment, gum recession treatment and cosmetic gum treatments.
