Reared into an atmosphere of unparalleled focus and a passion for excellence since his childhood days, Dr. Gerry Buenaventura devoted his young life into the practice of dento-facial orthopedics, making him one of the most popular in the field of orthodontics in the industry today. After graduating from the University of the East in 1989, he pursued further studies in orthodontics from the University of Munich and enhanced his skills through further studies at the Universite de Rennes in France. He his currently G.A.O.C.’s visiting orthodontist and continues to engage in private practice, attending to his legions of satisfied patients.

Specialization: Pediatric Dentistry

Against the grand spectacle of commercial practice and moneyed recognition, Dr. Kim Coeli stands as one of the few competent and compassionate dental practitioners who shun the glare of glory and prefers to work silently at the sidelines, conducting a number of gratuitous dental missions to depressed areas and public schools. Having completed her dental degree from the University of the East in 2001, she currently works as an Associate Dentist at the Children’s Dental Center and devotes her time as a visiting pediatric practitioner at G.A.O.C. Her passion for positive action is only matched with her remarkable compassion for children, as she continuously shares her expertise in oral prophylaxis, tooth extractions, fluoride treatment and oral health awareness to elementary students nationwide.

He reached for a place in the Philippine dental industry by being one of the most dynamic young practitioners in the country today. Highly skilled in the practice of general dentistry, which now includes, among his vast array of specializations, endodontics, orthodontics, and dental implantology, Dr. Dennis Andigan is G.A.O.C.’s visiting endodontist. An academically gifted student, he landed at the top one percent in the 1994 licensure examinations for dentists, after graduating with flying colors from the University of the East’s College of Dentistry. He doggedly pursued post graduate training, specializing in basic and advanced endodontic clinical procedures – making him one of the most stellar root canal therapists in his field of expertise.

Specialization: Cosmetic Dentistry

His is a life of action and bold ventures with people and industry, of a uniquely personal triumph in search for excellence, of hopes raised for progress in his field of specialization. For Dr. Sonny Burias, G.A.O.C.’s visiting cosmetic dentist, aggressiveness and vision reined pre-eminent and is, in great part, the base for his outstanding accomplishments as one of the fastest-rising dentists, specializing in Cosmetic dentistry. A graduate from the University of the East in 1992, he worked as a dental consultant at the Kerr Dental Company Sybron in the Philippines, which exposed him to the inner workings of composite and esthetic restorative materials. He was the founding member of the Philippine Academy of Esthetic Dentistry and lends his services as a lecturer for esthetic and precise tooth preparation. Dedicated to the pursuit of excellence in his craft, he is involved in a continuing education program at the University of California in Los Angeles on restorative dentistry and prosthodontics.
