Meet Our Doctor

Alan Tan was born in Pennsylvania, but raised in the Bay Area, in the city of Sunnyvale. He and his good friend, Arnold, grew up with a keen interest in animals and science. It was always his intention to do something in the health field. During a college sabbatical in Colorado, he spent his time skiing, working, and volunteering at Aspen Valley Hospital while figuring out what he wanted to do with his education. A graduate of UC Berkeley with a bachelor's degree in biochemistry, he finished his studies there in 1986. Go Bears! That same year, he attended Tufts University School of Dental Medicine in Boston, Massachusetts. With a goal in mind and in sight, he excelled and graduated in the top of his class in 1990. All intentions were to return to California right after graduation, but after being accepted to the post-graduate orthodontic residency at Tufts, he stayed on in Boston for an additional two years.

Dr. Tan has been trained in orthodontics and dentofacial orthopedics, which means he not only treats teeth, but also understands facial growth and development. He is a member of the Sacramento District Dental Society, the Pacific Coast Society of Orthodontists, the California Association of Orthodontists, and the American Association of Orthodontists.

For 24 years, Dr. Tan has been practicing solely in Woodland, California and moved to his present location in an award-winning renovated Craftsman-style house in 2002. During this time, he has built a reputation of making great smiles, improving bites, and building self-confidence. Just ask around.

Dr. Tan and his team have a combined 130 years of experience in the orthodontic field. The team is what makes this place special. They understand the importance of customer service. Dr. Tan has taken the lead from businesses known for their customer service such as Nordstrom, Disneyland and Southwest Airlines, and incorporated this into his practice. He also gives back to the community with pro bono cases through the Smiles For Kids program, Sports guards for various sports teams at local schools, supports 4-H and FFA, sponsors Yolo county CASA (as well as sat on the Board of Directors for five years), speaks at local career days, raises funds at elementary school carnivals and festivals to benefit the school itself, among other endeavors.

In his personal life, he spends most of his time with his best friend and wife, Suzie. She started her own business, a 7200 sq ft dog hotel. It was a daycare and overnight camp for dogs which combined her 18 years of success as a manager in the investment management industry with her passion for our canine friends. She recently sold the business after a successful 4 years. When they do have free time, they visit with family and friends, travel, dine out, run, kayak, ski, swim and snowshoe.

Meet Our Staff

I’m so excited to be a part of Tan Orthodontics as the Marketing Coordinator. The first time I walked into the office, I could immediately tell the staff cared about each other and the patients. Dr. Tan and team are second to none – and they keep the office full of fun and laughter. I grew up in the Bay Area, received my business degree in Marketing from Santa Clara University, and worked in Silicon Valley before moving to Natomas and starting a family. I have three children, who keep me very busy! When we’re not on the soccer or baseball field, we love to travel and spend time outdoors.

I’ve come full circle at Tan Orthodontics – I used to be a patient and now I’m the Treatment Coordinator! I was born and raised in Woodland, so working here is a treat since I see so many familiar faces come through the office. I started my career in general dentistry, but I’m excited to now be working in orthodontics, especially since I always say a smile is the best kind of accessory! Now I get to help others improve their smile every day. I love spending time with my young daughter, and I also enjoying knitting and playing golf.

I have worked for Dr. Tan for two years as his lab and records technician. My favorite part about this job is the people I work with, as they are always upbeat! Also, I truly enjoy watching patients transform from shy non-smiling people, to people with beautiful confident smiles. I live in West Sacramento, and when I am not working I enjoy spending time with my husband and our poodle, biking around Midtown and Discovery Park.

Hello everyone! My name is Elisabeth Guerrero. My goal was to find a job in Woodland, where I grew up. Luckily, I found Dr. Tan's office and was offered an internship, and now I work here as an Registered Dental Assistant. Since I am bilingual, I also contribute to the office by assisting our Spanish-speaking clients. I love to get involved and help patients throughout their treatment. Being part of Dr. Tan's team makes me feel very fortunate to be part of this family.

We all want to belong somewhere and here is where I belong, somewhat like a home away from home. I am a long time member of the Tan Orthodontic Team. My position here is Financial Coordinator. My favorite part of working in the orthodontic field is seeing the smiles that we've helped to create over many generations.

Restoring our home and living in the Capay Valley has proven to be much work, but I am totally in my element being in the country. At the end of the day, my husband Bart and I find it most relaxing to sit and enjoy our view of the beautiful Capay Valley hills.

I’ve worked as a registered dental assistant in orthodontics for over 20 years – and I’m so happy to be back at Tan Orthodontics. The fun office atmosphere isn’t like coming to work; it is like going to a party! I grew up in Woodland, joined the Navy after high school and served for almost 5 years before becoming an RDA. I love to spend time with my family and friends, and I especially enjoy the company of my fur-babies Ed and Copper.

Hi! My name is Sondra and I have been an RDA in the orthodontic field for 30 years. My favorite part about working in orthodontics is getting to know the patients and watching their smiles change. When I’m not at work, I enjoy spending time with my family and friends along with my husband and our two daughters.

I’m so happy to be a part of the Tan Orthodontics family! I’ve worked in orthodontics for the past seven years as a registered dental assistant, and have always hoped to find a job close to home. I grew up in Woodland and currently live in town, so being able to work with Dr. Tan is truly a dream come true! I love spending time with my husband and two kids - who keep me very busy. I’m involved with Girl Scouts and PJP Cheer. I love to craft, bake and camp.
