If you’ve been around KG Strong for more than five minutes, you’ve probably felt Jenn’s presence—in the best way.

She’s ridiculously consistent, the first to offer help when someone in our community needs it, and somehow shows up for all the things (weekly Rooftop Yoga volunteering, hosting Book Club, events… you name it).

She has a special talent for making new people feel instantly welcome, and on top of all that? She’s strong as hell—and still getting stronger. We’re lucky she’s ours. 💜

Slay Bells 2025! 🎄⛄️❄️🎉

Big PRs, Simple & Sinister absolutely crushed, and a whole lot of laughs along the way. We collected a huge stack of coats for our coat drive — truly proud of this community. Finished it all off with a delicious lunch and great company. This is what it’s all about.
