Dr. Nielsen was born and raised in the Bay Area and is so grateful to be able to raise his family in the beautiful county of Marin. Dr. Nielsen majored in Zoology at Brigham Young University before attending dental school at the University of the Pacific in San Francisco where he graduated in the top of his class and was inducted into the Tau Kappa Omega dental honor society. Dr. Nielsen obtained his postdoctoral masters degree and completed his certification in orthodontics at the University of Colorado. He is Board Certified by the American Board of Orthodontics and an active member of the American Association of Orthodontists, California Dental Association and the Pacific Coast Society of Orthodontics.
When not in the office, Dr. Nielsen keeps very busy with his family. He and his wife, Bethany, are the proud parents of Evan, Dallin, Korra, Jace and Maggie. Weekends are usually spent attending various sporting events or hiking and exploring the beaches and trails of Marin and beyond. He has a gift for capturing the beauty in this world as witnessed in his own photos hanging in the office. Come and see!

The doctors and staff provide excellent care, and I'm happy to say that the Invisalign process fixed my very painful TMJ! I'm a 71 year old grandma who wore braces all through my teens, and I thought NEVER AGAIN. Now that I've gone through the process, I'd like to encourage other adults to consider this. I just wish I would have done it sooner. Thank you, Dr. Nielsen and team!

Dr. Nielsen and his staff are very warm and great at working with kids and teens. He has worked with all three of our kids and we couldn't be happy with the outcome and service thus far.
