Shaped by a childhood spent traveling due to her fathers military career, Dev developed a love for adventure, a curiosity about the world, and a drive to embrace challenges early in life. She settled in Montana in 2010, where the outdoors quickly became an integral part of her lifestyle. After meeting her husband, Mark, in college, the two built a life rooted in hard work, adventure, and a shared passion for community. In December 2025, they took the leap into gym ownership, turning a shared vision into reality.

Living in Montana has shown Dev and Mark that there is something truly special about this place and the people who call it home. There’s a grit, work ethic, and dedication here that extends far beyond the mountains and into everyday life. It’s a quality they deeply admire in the athletes who walk through DLD’s doors and one they’re committed to preserving in everything they do. DLD is more than a business to them; it’s a community, a shared vision, and something they’re incredibly proud to build together.

With over a decade of experience in the fitness industry, Dev has coached across multiple disciplines, while also mentoring and developing coaches. Her greatest fulfillment comes from watching people realize what they are capable of. She believes strength training is foundational, not only for athletic performance, but for longevity and everyday life.

Outside the gym, she has competed in multiple mountain races: The RUT, RUFA, Cody Peak Teton Runs, HYROX competitions, and embracing opportunities that test both physical and mental grit. Her coaching philosophy reflects this same spirit: train with purpose, build resilience, and become more capable for life.
