Your Watertown and Middlebury, CT Orthodontist

Dr. Mark purchased his practice in 2017, rebranding the office as Clauss Orthodontics.

He felt like it was a perfect opportunity to continue treating the patients and families he'd come to know over the years.

It’s All About You

When asked who his favorite patients are to treat, Dr. Mark says, "All of them".

Why? Because each patient goes through a physical transformation.

“You can see the change in their personality,” he says, “they become much happier people.”

On the Cutting-Edge

Dr. Mark stays sharp for his patients by taking as many continuing education courses as he can throughout the year, especially in Invisalign.

His professional affiliations and accolades include:

Away from Work

Dr. Mark and his wife Kelly have one son, Ethan.

In his spare time, he volunteers with Habitat for Humanity. He also enjoys restoring classic cars and skiing.

Dr. Mark is also a self-proclaimed “computer nerd” and claims to know a thing or two about video games – just ask!
