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.

Great experience here! I feel so much better after my Invisalign treatment—it’s great to have my smile back. The team is so knowledgeable, kind, and attentive. Highly recommend!

My experience with Otto Ortho. has been incredibly positive. The staff is attentive and always ready to answer any questions. My daughter is still covered under her plan, and I can confidently say that she is very comfortable with the team and the entire process.
Response from the owner:Thank you for taking the time to share this! It's always rewarding to know that the care and attention our team puts into every visit is making a difference.
Kyle S.
I’ve been trying to get Invisalign for a while. My regular dentist office has gave me the run around and the one ortho I met with prior gave lack luster service. Saw an Otto Orthodontics ad online and figured I’ll give it a shot. I was able to get scheduled within 3 days of inquiring and within my first hour long consult I knew they would take care great of me. Very easy process to begin and better payment options than the competitors. I look forward to beginning treatment in the next few weeks! Thanks!
Response from the owner:Hi Kyle! It was great seeing you today.. we are so excited to exceed your expectations! Congratulations again on your upcoming transformation - we are thrilled to be apart of it!
Autumn H.

Mary Grace has treated our family with the utmost respect during our visits to Otto Orthodontics. She remembers our family and takes great care of my son. I’d highly recommend this establishment to anyone looking for a kid friendly orthodontist.

After the first consultation my daughter loved the staff and very comfortable with the place! This is what made us go with Otto orthodontics! Ever since they have been very communicative and friendly! Love the point system they offer as well. Highly recommend them.

I absolutely love this office and had such a sweet lady who I spent most of my time with. She made me feel very comfortable and really guided me through all of my options. Highly recommend Otto Ortho for their great customer service and work.
Response from the owner:Thank you for your wonderful review, Susan! We're thrilled to hear that our team made you feel comfortable and well-informed. Your recommendation means a lot to us—looking forward to serving you again!
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!!
Response from the owner:Thank you, Stephanie! We're thrilled to hear about your positive experience with Nichole and the efficient process. Your excitement for the results motivates us, and we look forward to seeing your smile soon!
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!
Lisa H.
I am currently undergoing invisalign treatment with Otto orthodontics. I had a question/concern recently, they got me in and addressed it promptly. All was good! They put my mind at ease.
Response from the owner:Thank you for your wonderful review, Lisa! We're glad to hear that your concerns were addressed promptly and that you're feeling at ease during your Invisalign treatment. We appreciate your trust in us!
