"I was the kid who didn’t smile since he was 10. It’s now 26 years later and I can finally smile. I got quotes from three different providers. One of them wanted to pull 1 tooth and do metal braces for two years. One wanted to pull 4 teeth and do metal braces for two years. Then Dr. Underwood at Smile Doctors Orthodontics said he can do metal braces or Invisalign without pulling any teeth in 18 months. I conferred with my dentist who said “well you’re not growing any more teeth so I think the answer is obvious.” I just finished my treatment. The staff was always polite, helpful, and answered any and all questions or concerns that I had along the way. Having this done brought tears of happiness to my eyes. I would wholeheartedly recommend this practice to anyone looking for orthodontic work."

"Smile Doctors were awesome! They could have started my daughter’s braces a lot sooner than they did. The goal was to keep the total time for the braces short as possible. Her teeth needed some extra time growing in and they were amazing. Awesome staff and professional!"

Sadie Cohen
Dr. Sadie Cohen

Dr. Sadie Cohen earned her engineering degree from Miami University before pursuing her Doctor of Dental Medicine and Master of Science at the University of Kentucky, where she also received her orthodontic certificate. She was drawn to orthodontics for the opportunity to build long-term relationships and support her patients’ confidence and growth throughout life’s milestones.

When she’s not in the office, you’ll likely find her with her husband, Matt, and their Black Labrador, Mulligan, enjoying walks or relaxing at local coffee shops and breweries. A self-proclaimed foodie, she loves discovering new restaurants and recreating recipes she finds online.
