otto-matic confidence in every smile

Dr. Karkow, orthodontist at Otto Orthodontics, smiling in a white coat with the practice logo, representing expertise and care in orthodontic treatments.

Dr. Kirsten Karkow

Orthodontist

I love orthodontics. It’s a science and an art, and I’m proud to be in this field. Designing and creating gorgeous smiles is an artistic outlet for me, and I love working with all kinds of people to create their best smiles and watch their confidence grow. I also have specialized training in orthodontic care for patients with cleft lip and palate and special healthcare needs, and it’s some of the most meaningful work I do. It doesn’t matter how complex the case is. We can do this, together.

Education

  • Early Acceptance into Dental School
  • Doctor of Dental Surgery — University of Iowa
  • Master of Science & Certificate in Orthodontics — Marquette University
  • Serves on the St. Louis Children’s Hospital Cleft Palate and Craniofacial Team Under the Division of Plastic Surgery

Personal

I grew up in Manchester, Iowa, in a big family. My husband, Nick, and I now live in Webster Groves with our daughters, Ava and Knox, and love the community there. I love hanging out with family, exploring the STL food scene, being active, and practicing pretty much any type of art.

Katy G.
They are very willing, understanding and helpful to all needs. I have great experiences so far before my treatment and since my treatment for braces started in November. The orthodontist assts and Dr. Rowland are understanding and helpful, I have sensory issues with my mouth and teeth and they are always understanding and gives breaks too :) Always good experience!
Mandy D.
The staff was super friendly and personable. They took time to explain everything to myself and my son. Upfront pricing with no hidden costs, love it!
Response from the owner:Thank you for your wonderful review, Amanda! We're thrilled to hear that you and your son had a positive experience with our team. Our goal is to provide clear communication and friendly service. We appreciate your support and hope to see you both again!
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!
Response from the owner:Thank you for your wonderful review, Michelle! We're thrilled to hear about your positive experience with Dr. Larkin and our team. Making our patients feel comfortable and engaged is our top priority. We appreciate your recommendation!
