My Story

10 Aug 2026

This August, I am taking part in the Great Cycle Challenge to fight kids' cancer!

Why? Because we’ve all been affected. Most recently: in memory of an amazing friend Bruce passed away just last year and two: because of a wonderful girl I met who was far beyond her years and an inspiration to everyone around her who is gone too soon.

If you feel so inclined, even a $1 helps. Thanks so much I love you all!
