Leadership & Clinical Team
A Team Built on Experience and Consistency
At North Fulton Treatment Center, our strength is our people.
We are a small, close-knit clinic where every team member plays a vital role in patient care. Unlike many treatment centers that experience frequent staff turnover, we have built a stable, long-term clinical team. This consistency allows patients to form meaningful therapeutic relationships and receive care from professionals who truly know them.
Our team shares a common philosophy: treat every person with dignity, respect, and compassion while delivering the highest standard of clinical care.

A Unique Member of Our Team
Mabel
Mabel joined North Fulton Treatment Center in October 2024, proudly stepping into the pawprints of her beloved predecessor, Minnie, who retired after many years of service (though she still pops by to say hello sometimes!).
After completing her training in January 2025, Mabel quickly made her mark with her sweet personality. She’s best known for greeting clients with a favorite stuffed toy in her mouth and happily rubbing against their legs to say “welcome.” Mabel brings comfort, joy, and a wagging tail to everyone she meets — and she can’t wait to be part of your healing journey.
