Gilroy Family Dentist
Dr. Gary Banner

Gary Banner, DDS

I was born and raised in Gilroy. I attended Gavilan College and San Jose State University where I studied Biological Sciences. After, I moved to Southern California where I received my dental degree from Loma Linda University in 1992. Since my father, Dr. Alden Banner, was already practicing dentistry in Gilroy for many years, I joined him in his practice in 1992.

In my spare time, I enjoy traveling, playing the piano and spending it with my family.

Local Dentist in Gilroy

Georgina Starkweather

Office Manager/Registered Dental Assistant

Georgina has happily worked at Banner Associates DDS for over 10 years now. She graduated with honors from the Santa Clara County R.O.P. Dental Assisting Program, which began her career in the dental field. She started off as dental assistant intern then moved her way to a permanent position and eventually earned her RDA license. As happy as she was as an RDA, she jumped at the opportunity to work in the front office as a Financial Coordinator/Administrative Assistant. As the ever expanding office continues to grow with each generation of patients we hope to have her at this practice for many more years to come.
