Grand Opening Recap

Yolanda Chen

The rumors are true, Knoxville. Onsight Rock Gym is officially open to the public! We truly enjoyed our pre-opening member nights, and now we are so thrilled to share the gym with the whole Knoxville community. As I’m writing this, we have been open for just shy of a week. We kicked things off over the weekend with our Grand Opening Celebration Friday and Saturday. We couldn’t have predicted the overwhelming support we would receive from sponsors, volunteers, friends, family, and so many more. Each and everyone of you played such an important role in making the celebration and our overall opening a success. We can’t thank you enough!

We went non-stop Friday with the Evolv Shoe Demo, dinner form This is it! Pizza, music from Kukuly & the Fuego, Group Climbing Session with Coaches from Power Company Climbing, grip strength contest and crashpad stacking contest.

Saturday we started early with coffee from KBrew, yoga, Randori Speed Climbing Contests, face painting, chair massages, Kindermusik, food vendors, Catalyst Sports Demo, Boulder Better Clinic with Coaches from Power Company Climbing, Access Fund after party with beer from Saw Works Brewing Company and The Casual Pint plus music from The Jonny Monster Band, and Silent Auction and Raffles all day long.  

The funds raised from our Grand Opening will go towards scholarships for our High School Climbing League which will begin in the fall and Catalyst Sports - an organization that provides adaptive climbing opportunities for people with physical disabilities. We raised $1,366.00 through the silent auction for the High School Climbing League and $420.00 from raffle sales for Catalyst Sports! We are so thankful for those who contributed to our fundraisers and have helped provide access to more potential climbers.

We had a blast, and we hope you did too! Don’t worry, we will have plenty more fun events in the future! We even have programs to participate in currently for people of all ages and abilities. Check out our events calendar for classes, clubs, competitions, member appreciation nights, and more.

We hope to see you soon!
