MaryEvan Thacker Hellebusch, DMD, MS

A native of Cincinnati, Dr. MaryEvan always wanted to be a doctor. After becoming interested in orthodontics at a young age, she worked as a chairside technician at Thacker Orthodontics during the summer throughout her high school and college years and joined the team full time as an orthodontist in 2017.



After graduating from Saint Ursula Academy in 2005, Dr. MaryEvan attended Vanderbilt University to earn her undergraduate Bachelor of Arts degree in 2009, majoring in Biological Sciences and minoring in Medicine, Health, and Society.

Moving on from Nashville, Dr. MaryEvan next attended the University of Louisville School of Dentistry, where she earned her Doctor of Dental Medicine degree, graduating Magna Cum Laude and third in her class.

While there, she was elected to membership in Omicron Kappa Upsilon, the National Honor Dental Society, for her exceptional academic performance.



During dental school, Dr. MaryEvan received many awards, including:

  • American Academy of Craniofacial Pain Outstanding Senior Award
  • American Dental Society of Anesthesiology Horace Wells Senior Student Award
  • Professor Leonard C. Waite Outstanding Performance Award: Pharmacology and Dental Therapeutics
  • Top 10% in Basic Sciences: Microbiology, Pharmacology
  • Membership to The Delphi Society for outstanding academic performance and professional interest in biodental sciences

In 2014, Dr. MaryEvan completed a one-year Craniofacial Biology program at the University of Kentucky in their Department of Orthodontics. During this time, she and Dr. Jim Thacker worked together researching the clinical significance of mandibular dental arch expansion using an E-Arch appliance in the mixed dentition.

Dr. MaryEvan recently completed her three-year orthodontic residency training at the Boston University Henry M. Goldman School of Dental Medicine (where Dr. Jim Thacker also received his orthodontic training!) She graduated with a Certificate of Advanced Graduate Study in Orthodontics, and a Masters of Science in Dentistry from Boston University.


She Loves Her Patients

As an orthodontist, Dr. MaryEvan loves having the ability to create positive change in her patients’ lives by giving them a beautiful, healthier smile.

She knows that orthodontic treatment can be challenging, whether you’re a tween, teen, or adult, and it’s important to her that each patient feels welcomed, understood, and part of a team.

It’s exciting for her to come to work each day knowing she’ll be working with her patients towards the end goal of a great smile.

Outside the Office

Outside of orthodontics, Dr. MaryEvan loves all things outdoors. She and her husband enjoy exploring with their dogs, hiking, biking, waterskiing, and paddle boarding.

They spend lots of time at the lake in the summer and strap on snowboards and snowshoes in the winter. In her free time, she also attends pilates, spinning, barre, and other fitness classes to keep her healthy and fit for sprinting around the office every day.

Dr. MaryEvan is looking forward to building a new life together with her husband here in Cincinnati.
