A San Antonio native, he established his general practice in January of 1980.
Dr. Quillian consistently enhances his knowledge of modern dentistry techniques through continuing education courses, and he strives to deliver the most advanced dental care available today to his patients. He proudly claims title as a member of the American Dental Association, Texas Dental Association, Academy of General Dentistry and American Association of Implant Dentists. For 25 continuous years of membership in the pursuance of effective dentistry, Dr. Quillian recently received the Good Fellow Award from the Texas Dental Association. Over his dentistry career, he has also been awarded many postdoctoral training certificates in orthodontics, including Invisalign, endodontics, implants and, most recently, laser surgery with the revolutionary Periolase MVP7. In 2001, he was awarded the prestigious Fellow of the Academy of General Dentistry (FAGD) after accumulating 500 hours of postdoctoral dentistry education.
Dr. Quillian and his staff recognize that all patients are unique in their own right, each having their own set of values pertaining to their oral health. At Culebra North Dental Care, our qualified dentistry staff creates an atmosphere of open communication with our patients. We believe in educating each patient in order to create an individualized dentistry plan with the ultimate goal of a healthy mouth, healthy body and radiant smile.
While attending dental school, Dr. Quillian met his wife, Cheryl, who was a student in the dental hygiene program. Since their marriage in 1979, they’ve pursued their love of dentistry as a team in their San Antonio dental practice. They pride themselves on their three grown children and thoroughly enjoy their company every time schedules allow. When not utilizing cosmetic dentistry to deliver beautiful smiles to his patients, Dr. Quillian enjoys fishing, gardening, painting and traveling.
Dr. Quillian invites you to come into our San Antonio office and experience the difference true caring and individual attention can make for you and your family’s dentistry needs.
