Welcome to Our Office!


Welcome to Marcy Orthodontics with two offices conveniently located in St. Thomas and London, Ontario. Dr. Sean Marcy and his team take pride in offering the latest orthodontic solutions to suit your lifestyle and personal preferences. We are skilled in helping patients of all ages achieve a beautiful and confident smile.

Comfortable Setting

At our office, you are more than just a patient – you are family! We work together to provide personalized service and an enjoyable orthodontic experience in a comfortable, stress-free environment.

Convenient Hours

We offer evening and weekend hours to accommodate your busy schedule.

Innovative Technology

In addition to traditional metal braces and clear ceramic braces, we use the latest innovative technology such as Incognito Hidden Braces and Invisalign® clear aligners to enhance your smile through increased comfort and more efficient treatment.  We use digital radiography to provide a dramatic reduction in radiation exposure.  This state of the art technique provides a more detailed image without the use of harmful chemicals, so it is also more environmentally friendly.  Dr. Marcy utilizes computer analysis to ensure our patients receive the most effective diagnosis and we keep our office on the forefront of technological breakthroughs to provide the best orthodontic care possible.

As Green As We Can Be

We live in a world where concern for the environment and minimizing the impact of our consumption of renewable resources is a necessary and growing consideration for everyone.  At Marcy Orthodontics our concern for the environment and the health of our patients and employees is and will continue to be a determining factor in our choices of materials, protocols and technology for our orthodontic practice.  In trying to work with our planet instead of against it, these are a few of the steps we are taking to become as  “environmentally friendly” and as “green as we can be”.        

  • We use digital radiography.  This process uses no harmful chemicals in the processing so it is environmentally friendly and also provides a dramatic reduction in radiation exposure!

  • By using an electronic communication and records system, web-based technology for patient reminders and account access and email for correspondence & newsletters when possible, we are as "paperless as we can be".    
  • We are moving to recycled paper and vegetable-based inks for our letterhead for necessary correspondence and we recycle toner cartridges.

  • Practicing the 3-R’s (reduce, reuse and recycle) whenever we can, without compromising on health and safety standards.

Marcy Orthodontics is proudly committed to making decisions based on what is best for the community that we are a part of and for the environment as a whole.
