“My two daughters and I have all been patients of Dr. Simonsen. We were originally reffered by our general dentist and we are so glad we made the decision we did. Dr. Simonsen did an incredible job, and was always so pleasant during our visits. The staff was always friendly and made us feel comfortable during our office visits. We highly recommend Simonsen Orthodontics to our family and friends." -Jill M.
