Dr. Andrew Larkin

otto-matic confidence in every smile

Dr. Andrew Larkin

Orthodontist

Since dental school, Dr. Larkin has always been very involved in the efforts of organized dentistry. He feels this involvement is necessary to protect the integrity of the profession to ensure positive patient outcomes. Dr. Larkin practices with this same fervor in helping his patients achieve a smile that portrays confidence and beauty throughout their lives.

Education

  • Bachelor of Arts, Biology & Spanish — University of Kansas (with a 7-month study at the University of Costa Rica)
  • Doctor of Dental Medicine & Master of Public Health — A.T. Still University, Arizona School of Dentistry & Oral Health
  • Master of Science in Orthodontics and Dentofacial Orthopedics — Arizona School of Dentistry & Oral Health

Personal

Born and raised in southwestern Kansas, the Midwest is home to Dr. Andy Larkin. Dr. Larkin and his wife, Kim, love spending time outdoors with their daughters, McKenna and Isabelle, and their Bernadoodle, Stanley. When he is not chairside, you may find him on the golf course, tennis court, or in a deer stand. He is an especially passionate college and professional sports fan, so catching Dr. Larkin at Allen Fieldhouse to cheer on the Jayhawks or the Enterprise Center to root for the Blues would be no surprise.

Jessica J.
We visited Otto Orthodontics for a second opinion for my daughter’s need for braces. Not only were the staff warm and welcoming, they were able to significantly beat pricing from another office where our first consult was held. We look forward to working with them in the near future for our daughter’s orthodontic needs.
Tania P.
We had our 1st consultation, everyone was nice. We were able to get all the information (cost, timeframe, all the details and X-rays) we needed for my daughter to get braces. They were quick and very resourceful.
Salvatore C.
Both my son Frankie, and my daughter Cecilia have beautiful smiles. Thanks for the team at Otto!
Rachel D.
They are very detailed with explaining and super easy to get ahold of between calling and texts!
Tom S.
The team was always efficient, friendly and super helpful getting an 8 year old to be comfortable wearing braces and an expander for a year. Our daughters smile lights up the room now!

Today was my first time having Dr. Otto at the Des Peres location. I absolutely loved her, she’s so friendly, sweet and I love that she’s honest with her patients. She’s gentle and answered all of my questions I had. I highly recommend Otto Ortho!!
Jen N.
The office of Otto Orthodontics is great. My daughter has been going to their Fenton office for the last 2 years for treatment. Today she completed her braces regimen and we are so very happy with the results. The staff and doctors are friendly, knowledgeable, patient, and professional. I would definitely recommend their services.
