zak
Zak is great at connecting the dots. A past life as a globetrotting business management consultant bred a healthy respect for capability and a desire for efficiency. As a fitness enthusiast, the leap from coaching businesses to coaching athletes and individuals happened naturally while working and living in Dubai. Returning stateside in 2016 to start a family landed Zak back in his hometown of Dayton, and DSC quickly became a home base to work out the itch for continued physicality and progression as a new father.
Zak continues to rely on his process improvement & consulting background - still streamlining. Trying to find what is useful - and discard what is not - to develop a fitness experience that works.
