Meet The Team

Dr. Michael S. Tobian


To those of you interested in learning a little more about me... I am a loyal Bruin fan having graduated from both the UCLA School of Business and the School of Dentistry. I have enjoyed a general practice background ranging from private practice, to Hospital Dentistry, to volunteer programs for under privileged children. With over 30 years of experience, I have practiced dentistry for patients of all ages. I thoroughly enjoy the art and science of Dentistry. I consider myself a lifetime student, through which I can provide the highest quality of care for my patients. I have always placed a strong emphasis on thorough diagnostic procedures, which will lead to well organized and understood treatment plans. I like patients to be involved in the decision making process. Every person has their own treatment needs, costs and objectives which will ensure comfortable, meaningful dental care to last a lifetime.

A few of the professional organizations I belong to include: The America Dental AssociationCalifornia Dental AssociationContra Costa Dental SocietyDiablo Study Club (a local affiliation of the Seattle Study Club), the International Congress of Oral Implantologists, and an active member of the Partnership Study Club in Walnut Creek.

My wife Brenda and I recently celebrated our 24th wedding anniversary.  We enjoy spending time golfing and hiking.  Our son is graduating at San Diego State University and our daughter is a Junior at Cal Poly, San Luis Obispo.  To see them experiencing new beginnings and exploring their boundaries is amazing.  Of course, our Vizsla, Amber is part of most family activities.

Another passion of mine is golf. I have traveled around the world playing many famous courses. My ultimate fantasy would be to retire at age 60 and join the Senior PGA Tour, but Brenda thinks I should keep my day job.
