Dr. Andrew Larkin

otto-matic confidence in every smile

Dr. Larkin smiling in a white lab coat with "OTTO ORTHODONTICS" logo, representing expertise in orthodontic care at Otto Orthodontics.

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.

Although we don't go here anymore (double insured we needed to find a place that took both our insurance's) we absolutely loved it when we did! This office is truly full of dedicated wonderful staff that go above and beyond to make what can be a scarey experience so calm and inviting! The environment they created is fun and vibrant while still having that comfy cozy feeling making it a more relaxing experience than you would think possible for an orthodontist office. My girlie's really enjoyed the artwork and neon pink signs but they really thought it was cool the staff had matching shoes!! The kiddos like to dress up the same so that was like coolest thing for them! The best thing overall though was the ease of communication between the staff, orthodontist, myself, and my daughter! They just really made an effort to make you feel heard when asking questions, answering questions, explaining, just all of it!!! 10/10 I wish every office I HAD to go to was this way, I'd never miss any appointments! ๐Ÿ˜†
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear that you and your daughters enjoyed the vibrant atmosphere and dedicated service at our office. We appreciate your kind words and wish you all the best!
D D.
Beautiful office, friendly staff and doctors, most up- to- date technology. We are excited to start treatment in a few weeks!
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear you appreciate our office's environment and technology. We look forward to starting your treatment journey together soon at Otto Orthodontics!
Camme S.
phenomenal. EVERYONE on staff is so informative, polite, and courteous. They take time to explain things thoroughly and are helpful every step of the way ; they also offer flex payment plans. The software and advanced equipment is next level. The office is also so unique- fun and beautiful. I cannot stress enough how well my care AND aftercare has been. I would highly recommend
Response from the owner:Thank you for your wonderful feedback! Weโ€™re thrilled to hear that our team made such a positive impact on your experience. Your recommendations mean a lot, and we look forward to continuing to provide exceptional care!
Terry H.
I found Otto Orthodontics just last week. Their website and the team that answers phone calls say that they want to get to know you and truly care about their patients. I was shocked to find out that this is NOT just a slogan at Otto. They really mean it! My partner had a situation that seemed to be impossible for him to get the treatment he needed. The team at Otto was able to find a solution and make his treatment possible! The technology they have is awesome, you don't even need to have impressions with the yucky stuff everyone chokes on, it is like a 5 second laser instead. Incredible. I just can't thank everyone at Otto enough for their genuine care for folks. They deserve more than 5 stars for sure!
Response from the owner:Thank you for your wonderful review, Terry! We're thrilled to hear about your positive experience and glad our team could provide the care and innovative solutions you needed. Your kind words inspire us to keep delivering exceptional service!
Kaitlin T.
such a nice office! very modern boutique-style setup which made me feel super comfortable before my appointment. They also have really cute branding with their accent color being hot pink which I thought was so unique and fun. I came here to get Hawley retainers (my post-invisalign retainers are plastic and not working well for me) so I assumed I was going to have to do traditional mold impressions again ๐Ÿ˜ฃ but I ended up not having to! This office has an amazing scanner to digitally take impressions, so no gross putty or uncomfortable trays shoved in your mouth! ๐Ÿ˜ญ ๐Ÿ™Œ it was such a pleasant surprise and made the appointment way less stressful. all of the staff I interacted with were friendly and helpful :) I’d definitely recommend Otto if you’re looking for an orthodontist! ๐Ÿฉท
Response from the owner:Thank you for your wonderful review! We're thrilled you enjoyed our modern office and the digital impression process. Our team is dedicated to making your experience comfortable and enjoyable. We appreciate your recommendation!

The entire staff is wonderful! The information provided about options for orthodontics was thorough. The dentist took her time explaining information and allowing time for questions; she is very personable! The facility is clean and beautiful.
Response from the owner:Thank you, Jeanne! We're thrilled that our team made such a positive impact during your visit. It's our priority to provide comprehensive information and a welcoming environment. We look forward to seeing you again!

Melissa
I have been in invisalign treatment with this office for 2 years now. They are always professional, kind, and on point with all of their appointments. They are thorough and make sure you don't leave without addressing the next steps. 10/10 recommend them.
Response from the owner:Thank you for your wonderful feedback, Melissa! We're delighted to hear about your positive experience with our team. Your recommendation means a lot to us, and we look forward to continuing to support your journey!
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 staffโ€”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!
Conner L.
This place is so amazing! Everyone there is so nice and super fast at what they do! If it was possible I would give them 10 stars instead of just 5. I had an appointment on 5/12/25 with Kylie and she’s amazing at what she does!
Response from the owner:We truly appreciate your wonderful feedback! It's fantastic to hear that you had a great experience with Kylie and our team. Your support motivates us to keep delivering exceptional service. Thank you!
Macii P.
