Our team strives to give our patients the most pleasant experience and to be their personal advocate to meet the highest level of oral health and general wellness. 

Arlene Thompson - Dentist Office Manager



I have been in the dental field since 1991, starting off as a dental assistant. I had the pleasure of working with Dr. Mattingly as his assistant when he first came to work with the previous owner, Dr. Fastabend as an associate in 1997. I was cross-trained in both back and front office from the very start of my dental career, which makes my job easier knowing the intricacies of the doctor's needs and helping the office run seamlessly. As Office Manager, I aspire to continuously provide the utmost quality of care to our patients. I am very blessed to work with an amazing office and dedicated team that share the same work ethics. 


Outside of the office, I enjoy the outdoors – hiking, cycling, running, traveling, reading, and most of all, spending time with my husband and three children.

I hail from New York City and began my dental career as a Dental Tech, while serving in the Navy Waves in ’67.

On a personal note, I also taught aerobics for about 10 years, in the mid 80’s - 90’s, danced jazz in a chorus line and have flirted with ballroom dancing. I reside in Benicia and have a 12 year old, Shiba Inu named Suki, meaning “love“ in Japanese.
