In Their Words

Why Our Doctors Chose Smile Doctors

Smile Doctors is unique among orthodontic service organizations because of our “freedom within a framework” model. As the fastest-growing orthodontic service organization in the country, our comprehensive support services include operations, accounting, marketing, technology, and more. Through collective purchasing power, preferred supplier agreements, and many other business management solutions, we help doctors in whatever capacity they need.

Moreover, experienced doctors with established practices and recent orthodontic resident graduates alike join us because we empower orthodontists to focus more on what they do best—providing top-notch care for their patients—and less on anything else that gets in the way. But don’t just take our word for it. Discover why they joined, in their own words.

In Her Words

Why Dr. Ana Benedetti Chose Smile Doctors

“I felt like I was spinning. I couldn’t implement the things that I really wanted and make the changes in the patient’s life they needed. I felt I wasn’t present anymore. And that was a big deal for me. I went to school because I wanted to help people, not run a business. So, I saw an opportunity to grow and be with a company that would support my staff as well as support the lifestyle I was unable to create on my own.”

— Dr. Ana Benedetti

In Her Words

Why Dr. Tongco Chose Smile Doctors

You’re not going to find the Smile Doctors culture with another company or in another orthodontic practice. With numbers comes strength, and sometimes you lean on that strength, while other time you become that strength for someone else. That’s what I think Smile Doctors is: It is strong.”
