Hey everyone!
I’m Coach JD, and I’m super excited to be joining this awesome CrossFit Kids crew as a CF-L1 trainer! I’ve been doing CrossFit for about 8 years, and it’s helped me become stronger, faster, and more confident. I’ve even had the chance to compete, which taught me a lot about working hard, never giving up, and being a great teammate. I can’t wait to have fun, play hard, and help you all learn cool new skills while getting fit. Let’s crush it together and make this the best part of your day!
