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.


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.


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 a 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.


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.

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 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.

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 my smile is my favorite 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’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.


Hi! I’m Allie, and I’m so happy to be the first face you see when you walk into our office. I was born and raised in Woodland, and worked for Dr. Tan part time when I was in high school. After 8 years working in the medical field, I’m so glad to be back at Tan Orthodontics as the scheduling coordinator. In my free time, I love to go to the beach, spend time with family, and go on any adventure that might come my way. I’m an animal lover through and through - I’d love to own an alpaca one day!


I’m so excited to have joined the Tan Orthodontics clinical team as a patient coordinator. The office is friendly and fun – and I truly enjoy the fast pace environment. I worked in general dentistry previously, and I attended Carrington College receiving my RDA in 2018. Before joining the dental field, I worked at Starbucks. I love to shop and I’m crazy about my cats!
