STUDIO58 Performance was founded by husband-and-wife team, Erik and Bethany Kolb. By day, Erik serves as a firefighter and Bethany works in forensics. By passion, they are athletes, coaches, and amateur powerlifters dedicated to helping others unlock their strength and potential.
The 58 in the company’s name is a tribute to the 58 lives lost at the Route 91 Harvest Festival in 2017— an event Bethany attended that forever shaped her mission. STUDIO58 Performance is proudly built on resilience, strength, and the pursuit of constant improvement.

Who we are
Meet Your Trainers
Hey there, I’m Bethany! I’m a wife, mom of two energetic kids (and 2 equally wild huskies), and a lover of wine, coffee, and a good brunch! My deep-rooted passion for health and fitness began in 2011, and has been an integral part of my life since. I’m an NASM-Certified Personal Trainer with specializations in nutrition and corrective exercise. I’m dedicated to helping people move easier, become stronger, and build confidence—whether you’re on day 1 or year 10. I’m here to provide education, support, and sustainable habits so you can be the best version of yourself.
