Our Story

T3 Fitness was founded in 2008 by Sandi Vande Berg with a simple vision—to create a place where people of all fitness levels would feel welcomed, supported, and empowered to become stronger and healthier.

​

Today, that vision continues under the leadership of owner and sister Julie Edgar.

For more than 18 years, T3 has remained committed to providing expert coaching in a positive, encouraging environment where relationships matter as much as results. Every member is known by name, every training session is intentional, and every success is celebrated.
