Meet Dr. Timothy McSweeney

Helping People Achieve Amazing Smiles

Before I went to dental school and finished with a certificate in orthodontics, I studied mechanical engineering. I worked in the aerospace industry for six years before returning to school: I’m a "Smile Engineer" who brings together the best of both my careers to create each patient’s best smile!

I became a dentist in 1997 and spent the next two years in an orthodontic residency. I started practicing in Rhode Island in 1999, as one of five orthodontists in a very large practice. After three years, I realized I wanted to be my own boss and started looking for a practice to buy. I’m thrilled to have found what I was seeking in Plattsburgh and Saranac Lake!

Being an orthodontist is about helping people make lasting, positive changes in their lives. Having straight teeth improves a person’s oral and overall health. It also improves their self-esteem and gives them confidence, as they know they have an incredible smile. Best of all, their new smiles will last a lifetime!

I am humbled by the trust patients place in me and take that responsibility seriously. I understand each person has their own desires, as well as clinical and personal concerns. I encourage patients to talk openly with me about what they need from care. That gives me the best insight into how I can exceed their expectations and deliver the smile of their dreams.

Personal Life

I grew up in Guatemala City, Guatemala. Plattsburgh, NY has been home for my family for more than 15 years. My wife and I have been happily married for 25 years. We have two children: Connor, who is studying communications at St. Lawrence University, and Lucy, who is in high school. 

When I’m not working, I love time with my family. We enjoy hiking, skiing, and doing anything on Lake Champlain. I also really love to golf, though I’m not great at it. Still, I think walking around outside, on a beautiful day, is a wonderful way to spend a morning or afternoon. I enjoy playing volleyball and soccer, as well.

I help build the Drama Club sets and serve on the after-prom committee for Plattsburgh High School. I’m currently on the board of directors for the Champlain Country Club and am a former board member of the Noon Rotary Club and the Plattsburgh Middle School FSO. I was on stage with the Chazy Music Theatre for several years, and I still join my daughter, Lucy, on stage for the annual Nutcracker production.
