Interviewed by Dr. Yuna Park
Dr. John Callahan is a well-known and respected leader in organized dentistry and orthodontics. Most recently, he served as the President of the American Association of Orthodontists (AAO) for the 2024/25 term, concluding his Presidency at the 125th AAO Annual Session in Philadelphia. A longtime advocate for the profession, Dr. Callahan is also closely connected to the Northeastern Society of Orthodontists (NESO), having served as Trustee (2014-2022) and NESO President (2011/12). His extensive contributions to organized dentistry include but are not limited to representing NESO at the AAO House of Delegates, as well as participating on various councils and committees both with NESO and the AAO.
In this interview, Dr. Callahan reflects on his tenure as AAO President and shares insights from the Annual Session in Philadelphia – affectionately dubbed the “Biggest. Party. Ever!”
1.What a year it has been! Can you recall a particular moment this past year that made you feel especially proud to represent the AAO?
The AAO is highly respected in the dental and healthcare fields, both in North America and globally. I was pleasantly surprised and very proud of our AAO team when we sat down last summer with the US Food and Drug Administration to discuss issues regarding patient health and safety directly related to DIY. They took our concerns seriously. Our views were listened to carefully and there was meaningful follow-up, which is a testament to the respect we hold in the healthcare world.
2. What were your biggest takeaways from the 2025 AAO Annual Session and how did this year’s meeting compare to previous years, in terms of energy, participation, or innovation?
The AAO Annual Session is always the one event each year where the global orthodontic family can gather and experience great CE and a fabulous exhibit floor. It’s what everyone knows and expects. The intent of the meeting in Philly was to bring so much more. The goal was to provide an experience unlike any had felt in previous Annual Sessions. It was all about creating that vibe that made folks feel great about attending. And a desire to make sure one would not miss going to Orlando next year.
Both while I was attending in Philly and by the overwhelming positive feedback by members who attended, it was a spectacular success. It was the “Biggest Party Ever”!
The AAO is playing the long game. The changes felt by members in Philly are going to be the norm at Annual Sessions going forward. Go for the CE and Exhibits-leave feeling energized and full of great stories. How awesome is that!
3. Looking back, what legacy do you hope to leave as AAO President?
Reflecting on my term as AAO President, it has truly been an honor, and I have thoroughly enjoyed this role. Ultimately, it is for others to define what my legacy will be. However, I sincerely hope that the AAO’s strong commitment to emphasizing the sanctity of the doctor-patient relationship, which has been a central focus of my member messaging and the collective AAO advocacy efforts, continues to endure.
Here are three areas where positive changes occurred.
Collaboration– We have strengthened our relationships and built resilience as both a specialty and a profession by collaborating with like-minded organizations. This collaboration includes not only other dental associations and international orthodontic groups but also vendors and government entities. It focuses on finding common ground, which often involves aligning our messaging.
Advocacy– As the AAO, we have emphasized the importance of the doctor/patient relationship as a fundamental principle and affirmed that orthodontic care should be delivered by trained orthodontists. Our message is being heard. It is essential to recognize that our accomplishments result from true teamwork; the legacy belongs to the entire AAO Board of Trustees, of which I am just one member.
Member services– We have recently introduced several valuable programs and services for our members, including the Wharton-AAO MBO, the Simon Sinek Leadership programs, and our BullyingBites initiative. These initiatives are particularly meaningful to me as they reflect our collective efforts and contribute to the legacy we are building together at the AAO.
4. What does AAO need most from its new and younger members right now?
Three things: Stay a member, stay a member and stay a member.
Even if there are moments when you aren’t sure.
Why? You are an orthodontist forever. Right now, you’re focused on what is best for your practice, your family, and your community. The key benefit for supporting the AAO on your lifelong journey is so you can focus on what is most important to you knowing that the AAO is focused on what you can’t do; advocate for you and your ability to treat patients as you want and communicate with consumers that orthodontics should be done by orthodontists.
5. Is there a message you would like to share with the next generation of AAO leaders?
Orthodontics is a rapidly evolving specialty. As members of N&Y, it’s important to recognize that you possess the knowledge, skills, and creativity to shape its future. How exciting is that!
As I noted in a previous answer, I believe that most N&Y members prioritize their patients, families, and communities. The AAO is here to support your growth as an orthodontist. More importantly, I see our role as doing what you can’t. We’re here to watch and have your back and elevate the specialty. We do the necessary advocacy so you can focus on what truly matters to you. The AAO’s mission is centered on you and ensuring that you can pursue your professional goals.
