Roman Garcia
As the Head Personal Trainer at Ajax Fitness, I bring over 14 years of experience in strength training, conditioning, and sports performance. I hold certifications from NSCA, TSAC-F, and ACE, and specialize in tactical strength and conditioning, working with athletes and individuals to enhance their performance.
Since beginning my career in 2010, I’ve had the privilege of helping a wide range of clients achieve their fitness goals through personalized, sustainable training programs. With a deep understanding of human physiology, I design workouts tailored to each individual’s needs, whether they’re looking to build strength, improve endurance, or enhance sports-specific skills.
My passion for fitness and wellness is deeply personal. I witnessed the drastic decline in my mother’s health, who went blind at 40 due to treatable diabetes. This experience drives my commitment to empowering others to take control of their health and prevent similar outcomes.
I believe in a holistic approach to fitness, where steady progress leads to long-term results. It’s not just about lifting weights-it’s about improving overall function, health, and performance in all aspects of life.
When I’m not training clients at Ajax Fitness, I continue to expand my knowledge of fitness, science, and the latest training techniques. I’m committed to helping people become stronger, healthier, and more resilient versions of themselves.

Shaylee Barthuly
Meet Shaylee Barthuly - your trainer, motivator, and accountability partner. I'm passionate about helping people feel strong, confident, and capable in their bodies. My approach to training blends structure and support - I'll challenge you to reach your goals while keeping each session fun, encouraging, and empowering.
I grew up on a cattle farm in Montana, where I learned the value of hard work, discipline, and resilience. Sports have always been a huge part of my life – soccer being my greatest love – and I’ve been fortunate to coach young athletes right here in the Roaring Fork Valley. My experience across a wide range of sports has given me a deep understanding of movement, athleticism, and what it takes to perform at your best.
My passion for health truly ignited when I discovered yoga. What started as a personal practice evolved into hosting yoga retreats in Bozeman, MT, inspiring others to build strength through balance and mindfulness.
I’ve been working in fitness since the age of 19 and hold certifications through the International Sports Sciences Association (ISSA) in Personal Training, as well as additional certifications in HIIT, Indoor Cycling, and multiple Yoga disciplines. Whether you’re new to training or looking to elevate your performance, I’ll help you build a routine that’s sustainable, empowering, and tailored just for you.
