Jen K.

I was treated in the Des Peres office for braces. Every part of the 24 month treatment plan has been smooth and efficient. Dr. Otto, Dr. Larkin and the entire staff are top notch and very caring. Everyone seems to enjoy their work life which leads to wonderful patient care. Also my teeth look great! 😁

April B.

They made our move from another state a breeze. The office staff is fantastic and so friendly!

Stephanie K.

What a great experience! From the initial visit and them explaining the plan and then to my placement was amazing! Nichole was awesome she explained step by step what the process was and I was in and out within an hour on my lunch break!! Looking forward to the end results!!

Antonia D.

Otto Orthodontics is fantastic! They’re efficient, appointments are easy to book, and I’ve never had to wait long to get in. I also really appreciate their use of modern technology and their up-to-date approach to orthodontic care. Highly recommend!

Casey B.

Absolutely love this place, They make it feel like you’re hanging out with friends. Would recommend them to anyone

Justin W.

Staff and doctor were friendly and straightforward. They were upfront with the price and their recommendations. They got us in and out quickly but we did not feel rushed.

Jill M.

Our daughter just finished phase one of Orthodontic work and we’ve been extremely happy with the results. The staff have been wonderful too!

Michelle W.

We had a fantastic experience at Otto Orthodontics today for my daughter’s initial consultation with Dr. Larkin. He recommended a palate expander as part of her treatment plan to address her overcrowding during phase 1, which I really appreciated. What stood out most was the staff—they were incredibly kind, patient, and genuinely engaged with my daughter. They took the time to listen to her (even when she was being a little silly!) and made her feel completely comfortable instead of rushed. The entire visit felt welcoming and thorough from start to finish. My only regret is not choosing Otto Orthodontics for my own treatment last year. Highly recommend!

Amy A.

We have had such a wonderful experience at Otto! Every appointment was on time and each treatment was explained so well. I highly recommend Otto!

Emmy K.

Dr. Otto was able to have our son come in outside of office hours to repair his appliance that came undone. We appreciate the quick and attentive response to his needs!!

Sara B.

The doctors and staff have all been wonderful here. My daughter has a complicated situation with missing teeth and the varied options were explained to us with thoughtfulness and care. Very pleased we and chose Dr. Otto as our orthodontist.

Susan C.

What a great Orthodontic office. Everyone was professional and easy going. The group took care of my old retainer and put a new one in. I will be going back and highly recommend Otto Orthodontics to anyone looking for care.

Tammy R.

I cannot recommend this practice enough! Every time I walk through the door, I am always welcomed with a smile from staff. Being an older patient, I always wished for a better smile. Without question, The Wentzville team made my Invisalign journey incredibly smooth. The team is professional, the office is efficient, and my teeth look absolutely perfect. Thank you! If you are thinking about getting orthodontic work, this is definitely the place to go!!

Christine S.

Michelle has taken such good care of our son. We have had a great experience and know we are in great hands!

Alana G.

Warm and welcoming staff, I was very upfront that we came in for a second opinion about braces. They answered my questions and I didn’t feel pressured to make any decision on our first visit. Very impressive first impression.
