Heather Schaknowski

I decided to get Invisalign and could not be happier with the results! I highly recommend Dr. Stoll and his staff
for orthodontic care and the drive from Broomfield is under 20 minutes! They took time to answer all of my questions, were always personable, and genuinely wanted to make sure I was happy with my results. My experience was such a positive one that I plan to send both of my children to Dr. Stoll when they need braces. Thank you to Dr. Stoll and his awesome staff for helping me get my smile back!

Jesica Hauck

This place! And ALL the staff members are amazing! Before finding Stoll Orthodontics, I went to another place to inquire
about getting my teeth straightened and was told that they would have to remove two teeth from the top and two from the bottom due to the crowding. They are my permanent teeth!!! That was crazy to do so I did not end up getting braces at that time. Then about a year later I found Stoll Orthodontics! None of my teeth had to be removed! I had a stubborn tooth that kept me in them longer than planned but Dr. Stoll didn’t give up on it and now I have the smile I have always wanted! I can’t say thank you enough!!! THANK YOU DR. STOLL!!! And THANK YOU to ALL of the staff! J.H.

For 27.5 months, I worked with the entire Stoll Orthodontics Staff. I feel I got to know them on a personal, as well
as a professional, level. Their hard work, dedication, commitment, and positive attitudes showed up everytime I walked into the office until I walked out…and it wasn’t just a few staff members at one time or another. It was Everyone Everytime! Their Mission Statement says they provide the highest quality orthodontic care and service for all of their patients and families. Their patients are their #1 priority and they will always treat the patients with utmost respect and compassion. THIS is what I received from everyone at the Stoll office for over two years. I was a member of Team Stoll with Dr. Stoll at the helm. My smile is now the most beautiful smile I have ever seen thanks to everyone’s hard work and dedication. I could not be happier! I am grateful to everyone for their dedication and commitment and I will never forget any of them!

AJ Gustafson

We met with 4 orthodontists and decided on Stoll. Board Certification was an important criteria for us, as well
as doctor’s two-way communication style where he clearly explains what treatment he is planning and why he feels it is best. The “why” part is especially important to us. We are 7 months into treatment and are just feeling very confident about how things are going. It was a good decision for us.

Stoll Orthodontics has been the orthodontist for all three of our children. Each child has been cared for like family.
Dr. Stoll always remembers to ask our children about the activities in which they are involved. The staff care is always professional and each of our children has beautiful teeth. We HIGHLY recommend Stoll and are so grateful for their care and friendship with our whole family.
