A Message from Dr. Keith White

To All My Patients:

It is with mixed emotion and deliberation that I am announcing my retirement from dentistry in transition to the next chapter of my life. Most of you that know me, know I have many interests so this likely means I will not be slowing down.

There is so much that I want to say, but I want to keep it simple and from the heart.

Thank you all, who have given me the honor and the privilege of being your dentist. Your trust and confidence in me and my staff (who are amazing) is humbling. I have been rewarded personally and professionally, and take with me so many good memories and relationships. It is my hope that you know I have done my best for you, and that I will forever consider you first and foremost my friends.

It is also my desire to enter this transition knowing that you are in competent and caring hands. As a result of careful consideration I have found Dr. Benjamin Geleris, whom many of you have already met. I trust Dr. Ben to take excellent care of you. In the time that I have worked closely with him I have been impressed with his dedication to providing compassionate, high-quality care to his patients. Dr. Ben has shown a high degree of competence, and a willingness to work hard to improve his dental skills through continuing education. He and I, along with Dr. Bret Annoni and Dr. Jon Geleris, share the same philosophy of excellent care that you have come to expect and deserve. He is a great fit for this dental practice. You are in good hands with Dr. Ben.

Dr. Ben received his undergraduate degree from Chapman University in Orange County, CA. He then went to the University of Detroit Mercy School of Dentistry in Michigan. After school, he decided to move back home to California in order to be closer to family and friends.

Prior to joining us full-time, Dr. Ben practiced in San Anselmo for Dr. Goldstein and Dr. Costella. He is an active member in the California Dental Association, Academy of General Dentistry, and the Spear Education community.

Dr. Ben is newly engaged. He met his fiancé, Ashley, at Chapman University. Ashley is a special education teacher in Oakland. They intend to find a place close by once they are married. Dr. Ben coaches volleyball in his free time at a local volleyball club. His other interests include playing basketball and volleyball, hiking, reading, and learning the guitar.

Dr. Ben will continue to work as I did with Dr. Bret Annoni and Dr. Jonathan Geleris (his brother). And of course, with our staff whom most of you know well. Together the team will strive to deliver the care that sets our office apart from the others.

I wish you all the very best in life. May you be as rich in blessings as I have been.

Sincerely,
Keith T. White
