William Vainer, DDS was established in 1984, providing high quality, affordable dentistry in Campbell.  Our office has flourished with the trust of our patients, their families, and the local community. 


We take a conservative approach to dental care, explaining all options to our patients before we begin, and avoiding unnecessary treatment.  Friendly and family oriented, we cater to all.


Dr. William Vainer Sr. grew up in beautiful Santa Clara Valley.  He graduated from San Jose State University with a Bachelor's in Biology and a minor in Chemistry.  He then graduated from the University of Southern California as a Doctor of Dental Surgery, and has been practicing in San Jose for over 30 years.

Dr. William Vainer Jr. lives in Santa Cruz.  He joined the practice after graduating with a degree in Biology from University of California at Santa Cruz and a DDS from the University of California at Los Angeles.

Our office continues to grow with a fantastic team of dental assistants and hygienists as well.  The majority of the staff has been here over 10 years!  


By now, many of our original patients have had children, and their families have now become patients, too!  We are multi-generational,  and nothing makes us more proud than the continued confidence our patients place in us.

We welcome you to find out why so many of our patients are patients for life!
