ABOUT

TUFF MISSION


We exist to bring confidence and community to a life ventured outside.

We have a vision to inspire you to turn obstacles into opportunity, and explore your TUFF. 

Dave Sheek and Amanda Nauman started Sheek Group LLC in 2019 for the purpose of launching Mammoth TUFF.


Over the years, the TUFF brand has evolved from its humble beginnings and become a beacon of inspiration for many.


We believe everyone is TUFF in their own way and we invite you to explore your version of TUFF with us.
