Clifford O. Marks, D.D.S.

Dr. Marks received his B.S. from UC Berkeley before earning his D.D.S. from the UOP School of Dentistry in San Francisco.  He has been a proud member of Hughes Dental Group since 1988.  He is also a member of the Santa Clara County Dental Society, the California Dental Association, and the American Dental Association.  Although he sees patients of all ages, his passion is treating older patients with complex medical and dental issues.  This passion was fueled by serving patients with unique needs in the years he worked in various Bay Area skilled nursing facilities.  

From his years of practicing dentistry and taking greater than 1,500 hours of continuing education courses, Dr. Marks has successfully blended his skill and his compassion into the ability to offer high quality dental care in a most caring and considerate manner.  Dr. Marks likes to make sure his patients have every question answered before and after any dental procedure.  He knows each patient is unique and "one size dentistry" does not fit every patient.  What works for one patient may or may not be the best treatment for another.  Dr. Marks will work with his patients to come up with the best treatment plan for that individual.

Dr. Marks is a big 49ers fan!  He has endured the ups and downs of the team since the John Brodie era.  He looks forward to the ups once again in the upcoming season.  Dr. Marks also loves to travel.  Australia, Ecuador and Peru have been postponed due to Covid-19 but future reservations include New Zealand, the South Pacific and a return trip to China.
