Dr. Chad Jensen


Dr. Chad Jensen graduated from Indiana University School of Dentistry in 2001.  His General Practice Residency with the Veterans Administration at McClellen Airforce Base provided practical knowledge of dentistry.   In July of 2002 he joined the Colfax Dental Center, and has enjoyed providing excellent dental care to residents in Colfax and surrounding communities.   

Nestled in the beautiful sierra foothills, Dr. Jensen and his wife Deborah feel they could not have found a more suitable location for raising their two children. 

Some of Dr. Jensen's favorite hobbies are mountain biking, snowboarding, four wheeling and running.  

Dr. Justin Diederichs


Dr. Justin Diederichs graduated from Loma Linda University School of Dentistry in 2011. After settling in the foothills and practicing in Auburn for seven years, he moved to Colfax Dental Center, taking over for the retiring Dr. Zendner. He plans to continue providing the same quality, caring dental services for the residents of Colfax that they are used to receiving.

Dr. Diederichs lives in Meadow Vista with his wife Kara, and their three children. They stay busy with running their kids to and from, and coaching their various sports. When he gets a minute to himself Dr. Diederichs usually splits his time between projects around the house, the golf course, and the lake once the weather gets warm enough.

Dr. Diederichs has continued his education, and has taken courses on the placement and restoration of dental implants and root canal treatment, as well as staying up on the latest advances in materials and technology. He is excited to be able to take care of the wonderful people of a community that has been such a blessing to him and his family.


Office Manager

I've been with Colfax Dental Center for over 18 years. The best thing about my job is the people! Not only the ones I work with, but ALL of the patients that come to our office. We truly care about you and its reflected in the office atmosphere during your visits. My husband Jim and I were raised in the Colfax Community and have raised our family here, who still live close by.  


Registered Dental Hygienist

Hi my name is Mary, and I am a Registered Dental Hygienist. I've had the great privilege to call Colfax Dental Center my work home since 1994. We have the greatest patients, the best dentists and staff. It is a joy to spend Monday-Thursday with my work family. My husband Randy, and I have called Auburn home for over 40 years. We are living in our forever home located close to Old Town which Randy designed and built. Over these years we have had a blast raising our three great children Jennifer, Brandon and Jonathon, and now we are thrilled to be grandparents! In my spare time, I love to dance, workout, hike and be creative in my beautiful yard. Hope to see you at Colfax Dental Center!

Cat is super knowledgeable and has a gentle hand with all of her patients, they love to come see her year after year in our hygiene department. If you were lucky enough to have been a patient of Dr. Zendners, you might recognize her as his daughter. We are so lucky to have Cat here in the office to serve the community of Colfax and beyond!


Registered Dental Hygienist

Kim is such a blessing to our hygiene department. She is wonderful, both personally and professionally. 


Registered Dental Assistant

Hi, I'm Tanya! I started as a Registered Dental Assistant in 1999, and started at Colfax Dental Center in 2007. It was an easy transition because I was already a patient since childhood. I was raised in Colfax, but attended college in Toronto, Ontario, and Sacramento. The loves of my life are my son Mason and my golden retriever Pluto. During my free time I enjoy all things outdoors like: working in my yard, music, spending time with friends and family and volunteering. I love working at Colfax Dental because we have amazing patients and staff! 


Dental Assistant

Laurie is one of our back office assistants. If you were in the office at any point and heard laughter, most likely it was Laurie. We love her sassy spirit and kind heart. She has graced the office for many years and many of our patients come in just to say hi and visit with her. She is a great part of our Colfax Dental Center family!


Dental Assistant

Krista works in our back office and does so much in the office in general. She has worked in different capacities within our office during her years here. Patients and staff love her! 


Registered Dental Assistant

I've been a Registered Dental Assistant since 1992 and I'm still enthusiastic about it. I love general dentistry for the variety that it provides, as well as helping patients improve their smiles and dental health while helping to alleviate a lot of fears and misconceptions they might have. I'm married and we live in the awesome little town of Colfax. I appreciate the scenery and the serenity to be had in a small foothill town after being born and raised in Sacramento. My spare time includes working in the yard, playing ball with our dog Molly, and loving on our cat Dee. I also enjoy movie watching with my husband. I like to travel and discover new and familiar places as time allows. 


Schedule Coordinator

I started with Colfax Dental Center in 2019 I love this Colfax community and I find that I learn new things about this area all the time. I'm very blessed to have my two kiddos, a wonderful hubby and a whole bunch of animals that occupy my time outside of work. In my spare time I like to hang out with my family, ride my horse, take dance classes, play with my Cricut/craft, visit friends and work around my house and property. I like to stay busy! I look forward to getting to know you and your family while in our care, see you soon!
