Meet the Coaches

Casey Williams

Union Fitness Manager

Casey, a Pittsburgh native, grew up playing high school football at Moon Twp. Afterward he went on to play at Bucknell University as a two-year captain, graduating with a degree in Economics. He entered the workforce in the oil and gas industry, while at the same time pursuing his passion of powerlifting. Six years later he left corporate America for the opportunity to share his knowledge and drive with fellow Pittsburghers. In a relatively short period of time he reached some bench marks like a #6 all-time ranking in the 242lb weight class, as well as a #2 current world ranking in that same class. Strength and rehab are his specialties, so it only makes sense that the goal at Union Fitness is to allow members to flourish in terms of their own strength and health.

Alison Yee

RYT 200, CF-L1, USAW Sports Performance Coach

When Alison was living at the bottom of Nob Hill, San Francisco in 2006 and she decided to take up running, there was nowhere to go but up. Soon, not even San Francisco’s formidable peaks could hinder her hustle. After the birth of her twin girls she returned to her hometown of Pittsburgh, where she discovered CrossFit and Yoga. Now she spends her time challenging family members to competitions of strength in their makeshift garage gym, practicing downward dog with her daughters and chasing that blissed out post-workout high. Alison’s Bachelor of Arts in Communication from the University of Pittsburgh provides her with the ability to communicate her passion for fitness, specifically Olympic Weightlifting and Recovery Yoga, to the many different athletes, yogis and lifters with whom she works. Alison has her own style of teaching so we’re excited to integrate her knowledge and programming into our community. As a melting pot of experience, Alison is an integral part of the machine that is Union Fitness.

Lindsey Pogson


Lindsey has a passion for helping beginners find their way, particularly to the barbell. She ditched her stressful office job to follow her passion for strength training and conditioning here at Union Fitness. As a certified personal trainer and powerlifting coach, she uses an approach that corrects faulty movement patterns and improves stability before moving on to tackling the big three lifts. She also loves teaching our group training classes, particularly the U.Fit Bootcamp class where she gets to challenge people with bodyweight movements and and high-intensity intervals. In her free time, Lindsey competes as a powerlifter and spends as much time outside hiking and kayaking as she can (when the Pittsburgh weather allows it).

Jocelyn Dietrich

Yoga Teacher

Jocelyn’s first experience with yoga was through her college gym class, where 8 AM yoga began to take precedence over staying out late the night before. Jocelyn started to practice yoga regularly, learning peace and patience, and using it as an escape from college and post-college life stressors. She progressed and pursued a deeper practice by completing her RYT200 with Om My Yoga Academy in Harrisburg, PA where she studied in great depth not only the physical practice of yoga but the practice of the mind and spirit as well. She’s certified with the Yoga Alliance, is a Reiki practitioner, an Ayurvedic bodywork healer, and has a love and passion for all things flow – yoga, hooping, poi, etc. She also loves a good Powerful class! Jocelyn hopes to help others find a peace and comfort in yoga, both physically and mentally, to overcome false . limitations set by the mind through movement and breath. She strives for people to leave her class feeling peaceful, strong, fulfilled and eager to continue practicing yoga.
