Skyler is from Napoleon, Ohio and attended Hillsdale College with a focus on biochemistry and exercise science, while playing football for 4 years. He first came to PowerStrength during one of his summers to perform an extensive internship and train with our college athlete group.
In 2014, Skyler moved to Grand Rapids to begin at PowerStrength full-time. Since then, he developed within the team and now humbly serves as our Director of Programming and Training. He also coordinates our Internship Program and Nutrition Program. He is certified as a Certified Physical Preparation Specialist (CPPS), Precision Nutrition Level 1 Coach (PNL1), Certified Speed and Agility Coach (CSAC), and Certified Group Fitness Instructor (ACE GFI).

Skyler was never massively talented as an athlete but always prided himself on his work. Unfortunately, his athletic career was cut short by a serious hip and back injury. He now brings his attention to detail and work ethic to learning and coaching so that our clients always get the most out of the work they put in and they can control the “controllables”.
