The Doctors at Hollevoet & Welk Orthodontics have provided tremendous care for myself and kids! The staff were always so kind, safe, gentle, and game for some good humor. We are lucky and blessed to have such top notch orthodontists in Bismarck ND! Thank you all for leading the way to a great smile!
What an amazing group of people from start to finish. I went through Invisalign with them and the entire process was so easy! Tom and Dustin are so nice to work with and are perfectionists about your results. I could not be any happier with my experience!
Dustin and Tom are top notch, high integrity, super empathetic professionals. The support staff are simply awesome. No one 'wants' to see an orthodontist but if anyone 'needs' to see an orthodontist, I would recommend Hollevoet & Welk Orthodontics without any hesitation whatsoever.
Our family highly recommends Hollevoet & Welk Orthodontics! Four of our five family members are currently receiving dental care. Hollevoet's team is extremely personable, professional and genuine. We have been very pleased with not only the results, but with the process from start to finish.
Dr. Hollevoet and Dr. Welk are absolutely wonderful. I was somewhat hesitant about orthodontics as an adult, but the entire experience was very pleasant. I found the entire staff to be very pleasant and helpful with scheduling my appointments and with the treatments I received. I could not be happier with my experience and my straight teeth!!!
These two doctors are AMAZING!!! Not only are they professional and do beautiful work, but they like to have fun along the way!!! They make you feel like family!!
Dr. Hollevoet and Dr. Welk have been so great to work with! They are so caring and professional! They completely put our child’s anxiety to rest. She actually looked forward to her appointments and visiting with the entire staff at Hollevoet Orthodontics.
