  • Grant Koster

    I have been a board sports, consumer, and connoisseur since age 5, dating back to 2000. That means I have been chasing the white winter wave for 24 years. I worked at Boyne Country Sports as a snowboard pro and "Goggle Guru" for many years. I have worked as a snowboard instructor as well. I have conquered some of the sickest parks and most dangerous backcountry offered by the upper peninsula and mitten of Michigan. I am constantly searching for and thrive from getting extreme air, flexing major steeze in the park, ripping through deep powder, insane cliff drops, a good challenging adrenaline-pumping backcountry adventure and more. It warms my heart and soul to not only teach but also put a smile on someone's face when they find the perfect gear that suites their needs and wants.

    Thank you Grant
    Grant's message came the same day as my sons' first outting. The younger son has grown so much since his last board. Grant has been very helpful in finding his last 'parent purchased' board. The details in his recommendations will help a lot in picking out the right board.

    Grant is a Guru!
    Grant was super helpful and very knowledgable. I explained my issues I had with my board last year and Grant knew right away I was on the wrong board and knew the exact board I needed to be on. Spent a lot of time answering all my questions. Thank You!

    There that is so much information out there about snowboarding. Changing Technologies, new players in the game, options, etc. I could not have made a successful, informed decision without using curated and being paired with grant.
