All three of my kids have had incredible experiences with Dr. Sebastian and the team. The results speak for themselves (and there was much to fix!), but more than anything we simply love Dr. Sebastian and everyone. So kind, funny, professional, and organized. I couldn't recommend this business more!

I have had the fortune of having both of my daughters work with Mountain View for the dental services. The last several years I felt like it has been a partnership to help my daughters overcome various dental inconsistencies that could have resulted in long term problems. Dr. Sebastian and his predecessor both were highly knowledgeable, extremely amicable, and the entire team offered first rate services. If I had a complaint it would be timing for appointments was occasionally difficult, but that is not uncommon in the medical field. I believe that they truly do offer the best orthodontic service in Longmont. I’m grateful for having worked with them.
