Owner & Head Coach

Jeffrey Birthler

Jeff Birthler has a contagious passion for fitness. He graduated and obtained a personal training certificate from the National Personal Training Institute in 2010. On his way, he discovered and fell in love with the sport of CrossFit. Jeff hasn’t stopped learning, and still seeks a well-rounded education within the health domain, going beyond physical facets. He has trained clients at several corporate gyms, including Fitness 19 and LA Fitness, as he established a CrossFit affiliation.

CrossFit Fierce Play was established in 2012 in a 500 sq. ft. garage. After a few moves and upgrades, it now has a permanent, 2040 sq. ft. location in Maple Grove. Jeff calls it “home”.

Coach

Mark Mancuso

Mark Mancuso started his fitness journey while enlisted in the United States Marine Corps. Like most individuals, at first, he only focused on bodybuilding type workouts. Mark learned quickly that focusing just on the aesthetics of the body would get you only so far. In 2013, Mark found out about Crossfit and fell in love with everything that it stood for.

In June of 2015, Mark was Honorably Discharged from the Marine Corps and returned from his duty station in Okinawa, Japan to his home in Maple Grove, MN. Not having any formal coaching in Crossfit he was on a mission to find a Crossfit Box to call home. Crossfit Fierce Play welcomed him with open arms, and he hasn’t looked back. Mark obtained his Level One Crossfit certification in November 2015 and plans to add additional certifications in the future. He also intends to compete in a variety of Crossfit competitions as opportunities arise.

Coach

Luke Faust

Luke Faust first began integrating CrossFit into his traditional strength training and conditioning in 2009. During his time at Purdue, Luke led and creatively programmed for a small group of student CrossFitters with little to no equipment.

Early in 2013, Luke suffered a major ankle injury and was unable to walk for two months. This humbling experience brought Luke to develop a knowledge base on injury prevention, increasing range of motion, and developing proper motor control patterns. During the same time, he was training at a variety of boxes and ended up falling in love with the great community at CrossFit Fierce Play, which soon became his home gym.

Through Luke’s background, he began helping other clients as they approached him with their own specific issues. This began the natural transition to coaching Mobility classes in June of 2013. Shortly after, in August of 2013, he received the CrossFit Level 1 Certification and officially became CrossFit Fierce Play’s second coach.
