Brad Cooley
Co-founder

Brad Cooley grew up in Georgia. After high school he joined the Navy as a Corpsman (naval medic). He served 6 years and completed a bachelors degree. Following his time in the Navy, he decided to get out and sell orthopedic surgical equipment in California.
After two years of surgical sales, he realized his passion lay elsewhere. Brad entered the fitness industry, marketing and selling gym equipment all over the world.

In February of 2013, Ned and Brad opened the doors to a new gym, FIITWERX, and workout concept they had created for the public. After franchising their concept in 2015 as FIT 36, they then re-branded again in 2021 to what you now know as “The FIIT Co”

Ned Matheson
Co-founder

Ned Matheson was born in Washington D.C. and spent childhood into adulthood in Northern Virginia. Ned moved to Colorado to attend CSU at age 22. After finishing school, he became a Wildland Firefighter. Ned moved up the ranks quickly, graduating to sawyer, one of the first responders who cut fire line with a chainsaw. This job demanded peak physical conditioning and he excelled at this. Eventually Ned was positioned as the head of physical training for the entire Fire Crew with Larimer County Sheriff’s Department. The position as fitness head and sawyer, led Ned further into physical conditioning and when his time in Fort Collins came to an end in 2007, he became a personal Trainer in Denver. He has been an active and passionate member of the fitness industry since.

Brendan Bellantoni
Head Fitness Coach

Brendan Bellantoni is a certified personal trainer and injury rehabilitation specialist who helps individuals return to pain-free movement and build strength for everyday life. He specializes in bridging the gap between physical therapy and long-term independence through corrective exercise, thoughtful strength training, and improved movement mechanics.

Although Brendan competed as a Division I football player and later as a semi-professional rugby athlete, his career was cut short due to injury. Experiencing the frustration and limitations of chronic pain firsthand led him to shift his focus toward helping others avoid the same setbacks. Today, his work is centered on helping everyday people move comfortably, regain confidence in their bodies, and stay active without fear of re-injury.

Originally from the New York City area, Brendan now calls Colorado home. In his free time, he enjoys snowboarding, hiking with his dog, trying new foods, and taking full advantage of everything Colorado has to offer.

Hannah Polshuk
Fitness Coach

Hannah started her coaching career at FIIT, but her passion for human movement and performance began long before that through her career in occupational therapy. Understanding how the body functions, adapts, and moves efficiently has shaped the way Hannah coaches today.

Movement has always been part of Hannah's life. She grew up swimming and playing water polo, later discovering a love for running, and recently found triathlon, the perfect combination of everything Hannah enjoys most. Whether training for her next race, heading out for a trail run, skinning up the mountains when there’s snow on the ground, practicing yoga at home with her two cats getting in the way, or walking her two dogs, Hannah is always moving.

Through my own experience with fitness, I discovered how powerful movement and community can be in contributing to overall wellness. As a coach, I’m dedicated to creating an encouraging environment where every person feels supported, motivated and empowered to become the best version of themselves.

Bill Byrnes
Yoga Instructor

Bill’s classes fuse intentional movement with conscious breath to build mental and physical strength. Every class is an approachable challenge designed to help students find their edge, deepen their mind-body connection, and leave feeling more alive than when they walked in.

Bill’s mission is to deepen connection with self and others through men’s groups, retreats, yoga, breathwork, and ceremony. He also loves shredding pow, trail running, cold plunging, deep conversations, and traveling around the world.

Colin is a performance-driven coach with a passion for helping people push beyond their limits both physically and mentally. With a background in physiology and athletic training, he focuses on building resilience, confidence, and discipline through intentional training and accountability. Alongside his coaching experience, he's training for both HYROX competition and marathon racing, he believes growth happens outside of comfort zones and carries that mindset into every class he coaches. Whether chasing a new PR, or exploring new places around the world, Colin is driven by adventure, personal growth, and helping others realize what they are capable of.

Tyler Grier
Boxing Coach

Tyler has been been coaching for 7 years. His background in strength training, HIIT, boxing, and Muay Thai heavily influences his coaching style. Tyler brings high energy into every class while focusing on movement quality, proper form, and creating an environment where people feel challenged and supported.

For Tyler, coaching goes beyond workouts. He enjoys building real connections, helping people push past limits, and reminding them that showing up for yourself consistently matters.

Outside the gym, Tyler is always seeking growth. Right now that looks like tackling longer hikes across Colorado and training for upcoming Muay Thai competitions. Tyler brings that same mindset of challenge, growth, and purpose into everything he does.
