History of the Practice

Dr. Richard Tokuyama first opened our doors in the Thousand Oaks/Westlake Village area in 1975. The following year, his USC Dental School classmate, Dr. Jim Osaki joined him in practice and they began building a legacy of excellence in oral surgery care.
Our second office was opened in Simi Valley in 1981, shortly before Dr. Scott Bennion joined the practice.  The group expanded further when Dr. Don Nikchevich, Dr. Tokuyama’s son-in-law, completed his oral and maxillofacial residency at USC in 1991, and then again 10 years later when Dr. Michael Newton joined the practice.  The practice opened a state-of-the-art surgical outpatient surgical center and added Dr. Wayne Ozaki shortly thereafter.
Since then Dr.Osaki, Dr.Tokuyama and Dr. Bennion have retired, and three associates have joined the practice in recent years.  Dr. Marine Sarkisian began in 2018, and her classmate from USC, Dr. Ara Mirzaians joined us in 2021.  In 2022, our third office, located in Glendale was purchased, and Dr. Rob Lytle, who had been practicing there for nearly 20 years joined the practice.
