Meet the Dedicated Team Behind Koen Orthodontics
At Koen Orthodontics, our goals for your smile extend beyond straightening your teeth. We also believe that orthodontic treatment should focus on building your confidence, creating connections, and making every visit an uplifting experience.
From the first time you walk through the doors of our Hendersonville or Cookeville offices, you’ll be welcomed like family. You’ll meet a team that’s genuinely excited to see you, that takes time to answer your questions, and that truly wants you to feel proud of your smile.
Every smile we treat is unique, and so is every treatment plan we create. Whether you’re considering braces, Invisalign, or early orthodontic treatment for your child, you’ll get the expert care you deserve, delivered with warmth, professionalism, and genuine passion for what we do.
Welcome to a practice where expertise meets heart. We can’t wait to help you achieve your dream smile!
Get To Know Dr. Tommy Koen
With over 35 years of experience dedicated to creating healthy, confident smiles, Dr. Tommy Koen brings expertise and heart to every patient he serves.
After earning his Doctorate of Dental Medicine and Orthodontic Certification from the University of Louisville, Dr. Koen returned home to Middle Tennessee with a mission: to blend world-class orthodontic techniques with the personalized, compassionate care that makes every patient feel like family.
At the core of Dr. Koen’s philosophy is a simple belief that the best orthodontic care starts with treating people right. That’s why he and his team focus on providing personalized attention, clear communication, and a supportive, team-based approach that empowers patients throughout their orthodontic journey.
Dr. Koen’s commitment to excellence is reflected in his professional affiliations, which include the American Dental Association, the American Association of Orthodontists, the Southern Association of Orthodontists, the Tennessee Dental Association, and the Tennessee Society of Orthodontists. He’s also deeply invested in his community, serving as a member and past president of the Hendersonville Rotary Club, the Hendersonville Chamber of Commerce, and the Sertoma Club of Hendersonville.
Beyond the clinic, Dr. Koen lives life to the fullest. He’s a licensed personal pilot – flying both airplanes and helicopters – and shares a love of adventure with his wife, Dr. Mary Cay Koen, who is also an orthodontist. Together, they enjoy scuba diving, snow skiing, and spending time with their two sons, Thomas and Michael. Their family is actively involved in the First United Methodist Church of Hendersonville, where Mary Cay’s father, Ben Alexander, served as Pastor Emeritus, further rooting the Koen family’s deep connection to the Middle Tennessee community they love.
