He later attended East Carolina University where he graduated with a bachelor’s degree in Health and Fitness. A short tour in San Diego under the direction of fitness expert Todd Durkin, allowed him the opportunity to work with NFL superstars such as Drew Brees, Aaron Rodgers, Shawn Merriman, and several others, which he claims to be paramount to his success as an effective Strength and Conditioning coach. He completed his Master of Science degree in 2010 from California University of Pennsylvania with a concentration in Human Performance and Injury Prevention.

“I was blessed to be in the presence of such great people throughout my earlier years in this business. Not only that, but I was fortunate enough to have them actually care about the direction I took in the field. To give anything less than everything I have to this gym and the people that believe in it would be disrespectful to all those great people that left their legacy within me. Thank you for all your support in helping us create one of the most unique and powerfully energetic facilities in Northeast Ohio.”

Holly is a graduate of and former cheerleader for Padua Franciscan High School. She graduated with honors from The University of Akron with a Bachelor of Science degree in marketing. After 10 years in the marketing and graphic design fields, Holly realized she needed a change from the corporate world. While always active, in 2008, she started Crossfit and found a passion for the sport of fitness. In 2010, Holly became an L1 certified Crossfit trainer and began a new journey to help others achieve a balanced, healthy lifestyle.

Holly has coached at 3 Crossfit gyms in Northeast Ohio and 1 in Georgia. She currently coaches individuals and group classes at 2 local Crossfit gyms, as well as Functions of Life. Holly embraces an active lifestyle within and outside of the gym. She enjoys competing at local Crossfit competitions, as well as various group classes, running, tennis, skiing, boxing and hiking in the mountains.

“I believe in balance for myself and my clients. “Life” happens and you can’t always make it to a class or eat the perfect macros in a day, but you can always do something to work towards being the best person you can be physically, as well as mentally. No one else can do it for you. Work hard in the gym so you can live the life you want outside of the gym.”

Mack is a graduate from Parma Senior High School, class of 2013, and received his bachelor’s degree in Exercise Science and master’s degree in Applied Exercise Science from Division II Ashland University. He chose to walk onto the football team in 2014 after deciding not to join the United States Marine Corps to pursue his dream of playing college football. During his time at Ashland as a college athlete, he earned the starting spot at fullback, became a three-year letterman, an accountability captain for two years, was awarded the Offensive True Grit award, Lifter of the Year award, and broke every weight room record for his position group. Mack was a part of the most winningest team in program history, winning two conference championships in 4 years. He continued his involvement with athletics at Ashland University while earning his master’s degree, working as a Strength and Conditioning intern, part-time volunteer position coach for the football team, and a graduate assistant in equipment management. Mack worked with Jump Start Sports as a Program Director and camp counselor during his early summers away from Ashland and more recently at Athletic Performance Training Center and D1 Sports Training in Columbus as a strength and conditioning coach.

“When training to pursue college athletics I met a great mentor in my life who changed my perspective on strength and conditioning and being a mentor for athletes. I found my passion for training during my early years as an athlete but never had a guide. When I got into college, I wanted to put myself in the best position for after graduation to pay it forward and be that mentor to provide anyone with road map to conquer any goal. I believe that if you hold yourself to a higher standard, remain accountable, practice self-discipline, work hard, and have an “I can” mentality, the sky is the limit for anyone! We are always capable of more! I can’t wait to share my knowledge and expertise with all of the members at Functions of Life, very excited for this opportunity.”
