Financial Coordinator

Hi! My name is Ali. I am one of the friendly faces you will see in our reception area. I went to school for dental hygiene in Austin, Texas, but decided that the administrative side of dentistry was where I could really make a difference. I specialize in patient finances and in helping you maximize your insurance benefits. I have been in the dental field since 2007, and I love it! There’s nothing better than seeing big smiles on people who finally have the smile they have always wanted. I look forward to getting to know you and helping you with your new smile!

I grew up in San Juan Capistrano and rode horses competitively for 16 years. My husband and I spend a lot of time outdoors camping, hiking, and simply enjoying nature. We love spending time with our family and hang out with our niece and nephews any chance we get. I also have two cats to keep me company at home.


Scheduling Coordinator

Hello! My name is Diane and I’m here to help you and all our new patients get started on their new smile.  I am originally from England and came to the United States 25 years ago.  I have 2 children and 3 step children, all in their 30s.  I love to walk the beach and am an avid reader.   

I have lived in Orange County for 25 years and for a while owned a company called "Flavor of Britain".  I also worked in the veterinary industry for years.  The thing I enjoy most about working at Olsen Orthodontics is seeing patients leave the office with big confident smiles. I look forward to helping you get the smile you've always wanted!


Treatment Coordinator

Hello, I’m Sim.  The most important passion in my life is helping others.  I feel so blessed to be a part of a team who cares deeply about making a difference in the lives of our patients. Not only with their smile, but also with their confidence and self-esteem.  As Treatment Coordinator, I love introducing new patients to our practice and answering their questions about procedures and appointments, as well as explaining financial arrangements and insurance benefits.  I work hard to make sure that our practice provides top-quality care and customer service.  

I was born in India, raised in Seattle and started a family here in Orange County. I have a lot of hobbies, like photography, crocheting, reading, and painting, but most of all I love spending time with my daughters.  I look forward to welcoming you as a part of our orthodontic family!



Back Office Assistant

I have been exploring the dental field since the tenth grade when I took an R.O.P. class and fell in love with dentistry. At Olsen Orthodontics, I make sure that all operations in the back office run smoothly. I am very outgoing, respectful, honest, fun, and motivated. I enjoy meeting new people and feel honored to have played a part in their straight teeth and perfect smile.

In my free time, enjoy playing a variety of sports, including soccer, racquetball, football, and basketball. In my free time I like to cook, work out, and play with my two nieces. Most of all, I enjoy helping people like you achieve an amazing new smile. I can’t wait to meet you!


Back Office Assistant

I assist Dr. Olsen with all aspects of patient care, including taking X-rays and impressions, doing orthodontic adjustments, and creating a warm, welcoming environment for our patients to enjoy. Watching as our patients’ smiles transform throughout their treatment is the best part of my job. I also really like the people with whom I work. Dr. Olsen is down to earth, very real, and understands everyone, young and old. Our team is very happy and well put together; it’s a very positive and happy place to work!

My husband and I moved here from Washington two years ago. We love the sunshine and love all kinds of outdoor activities, going to the beach, and spending time with our family and friends. 

Christina Dunn

PR Coordinator

I work with the community directly and on social media to promote healthy oral care, as well as the variety of services provided at Olsen Orthodontics. It’s rewarding to work with such a great team and the community, especially the local schools, to do my part behind the scenes to help make people smile!
