🌲 Volunteer Spotlight: Olivia Leseman 🌲

A huge thank you to Olivia Leseman for sharing her time and expertise at our Tree Climbing Competitions! Olivia served as a judge for the Work Climb and also supported timing for the Throwline (Throw Ball) event—both critical roles in helping our competitions run smoothly and fairly.

Her behind-the-scenes contributions help ensure every climber is supported in a safe, well-organized, and competitive environment.

💬 “I love meeting other like-minded tree care professionals at these events. It’s nice to connect with other people in our industry in a friendly competitive environment. It’s inspiring seeing the talent of others and it brings out a renewed excitement for doing what we love!”

We’re grateful for volunteers like Olivia who help make the TCC community what it is—collaborative, skilled, and deeply passionate about the work we do in arboriculture. 🌿
