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.

They where very patient with us and answered all my kids questions with out hesitation and didn’t rush out. They explained prices and how everything was going to work and made me feel confident that my kids teeth are going to be taken care of not just their teeth taken of but they was going to be taken care of too by people that care

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!
Donielle W.
I had my top braces put on today and had a great experience from start to finish. My appointment was right on time, which I really appreciated. The team explained everything clearly and made sure I understood what to expect during and after the process. They also gave great advice on how to properly care for my braces moving forward. Overall, very professional, efficient, and informative—highly recommend!
Response from the owner:Thank you, Donielle! We’re thrilled to hear about your positive experience with our team during your appointment. Your satisfaction is our priority, and we appreciate your recommendation. Welcome to your orthodontic journey!
Ashley G.
Walked in for a consult and left with braces for my 16 year old an hour and forty five minutes later. The most pleasant staff! Couldn’t imagine going anywhere else!

Otto goes above and beyond for their patients. From the initial consult to each visit- the staff is welcoming and information is readily available. They’re never too busy to take the time to answer questions. Appointment times are valued and you’re in and out quickly. Love the ability to text or talk on the phone with the staff. Thank you, Otto.
Response from the owner:Thank you for the kind words about our staff and for noticing the information we share along the way. We appreciate you.
Chanda M.
We have had such a wonderful experience with Otto orthodontist office! My son only had his braces on for 13 months, and part of the reason we had to wait a little longer was simply because we were waiting for some of his teeth to come in. Throughout the entire process, the whole team has been amazing to work with. One thing that really stood out to us was how accommodating and flexible they were. Even when our regular office didn’t have an appointment available, they gave us options to visit one of their other locations. No matter which office we went to, we were always greeted by friendly, helpful, and professional staff who made us feel comfortable. Everyone has been so patient, kind, and knowledgeable throughout my son’s orthodontic journey. We truly appreciate the care they provided and how smoothly they made the entire process for both my son and our family. We are so happy with his results and would absolutely recommend this orthodontist to other families looking for great care and a team that genuinely cares about their patients!
Response from the owner:Thank you for taking the time to write this. We are glad the experience with our office has been a wonderful one.
Tiffany K.
Everyone at Otto Orthodontics is incredibly friendly, welcoming, and professional. They took the time to explain everything thoroughly, making us feel comfortable and informed throughout the entire process. My kids actually look forward to going to their appointments, which says a lot! We highly recommend Otto Orthodontics to anyone looking for exceptional orthodontic care.
Response from the owner:Thank you for sharing your feedback! Our team is dedicated to providing a positive and professional atmosphere for everyone. We are glad to hear that effort is noticed.
