Danielle - Muay Thai Coach

She trained 5-6 days a week for a few years before turning most of her attention towards CrossFit. Over the years, she has attended multiple Muay Thai seminars, assisted in coaching kids' summer camps, coached fighter's strength & conditioning classes, and judged youth exhibition matches.
She started CrossFit in 2016 and has competed in a numerous of competitions. She was named "Fittest Woman in Lebanon" as she has dual citizenship, earning a spot at the CrossFit games, the highest level of CrossFit. She has also competed in Wodapalooza in Miami ,as well as our very own Battle at the Ballpark, although she prefers to judge these days. Her favorite part about our gym is the community.
Jason - Muay Thai Coach
Jason is a Muay Thai Coach and competitor. He started in 2007, after a short stint practicing Brazilian Jujitsu. Since then, he has trained in Thailand and attended seminars from Saenchai and Petchboonchu. The aggression and combative nature of Muay Thai is what attracted him to the sport, but the community and friends that he has made along the way is what has kept him in it.
He thoroughly enjoys coaching and seeing the progress of practitioners, regardless of whether they ever step into a ring. His favorite fighter is Sitthichai Sitsongpeenong.
If he's not practicing Muay Thai, he is hanging out with his daughter, hiking, kayaking, lifting and eating. If you need any restaurant recommendations, message Jason.
Katrina - Registered Dietician
Our nutrition coach, Katrina, is a Registered and Licensed Dietitian. She has over 10 years experience working with performance nutrition and weight loss. She got her nutrition degree from Benedictine University and did her dietetic internship and graduate school at Saint Louis University.
She loves helping people realize that they don’t have to starve themselves to lose weight and that athletes need a lot more fuel than they think. As a mom of 2, she enjoys helping new moms get back on track with healthy, mindful eating strategies. She is also a NASM certified personal trainer with a certification in Women’s Fitness Specialization.
Holly - Owner
Finally, our team wouldn't be complete without Holly. As you may have guessed, 309 Fitness is a family-owned business with Holly & Dorian leading this great culture and Dorian Jr. following in their footsteps.
Holly was "baptized by fire" with CrossFit when Dorian said he wanted to start the gym. She fell in love with it and became CrossFit Level 1 certified a few years later. Through her CrossFit journey, she learned that 1 in 3 women leak during physical activities, due to the intense pressure against the bladder. Through her own frustrations, she developed a line of leak-proof activewear, Moxie Fitness Apparel.
Her favorite part of owning the gym is seeing the transformations take place -- not just the physical, but the mental transformations. She loves the confidence that comes from exercising and the community of the gym. She also loves that her 2 younger sons, Tristan and Colton are also developing a passion for fitness and coaching others!
