Kevin Koe, Team Lead, 2016 Briar and World Champion of Curling*
"As a curler who competes at the highest levels I have suffered from knee pain constantly over the years. Two months ago I started taking SierraSil and started seeing excellent results after only two weeks. Now I am able compete and practice pain free and as an added bonus I have also noticed great improvements in my overall fitness due to being able to train off-ice without the typical aches and pains I typically would experience after a strenuous workout. I am definitely pleased with the product and plan on taking SierraSil going forward."
