My Story

26 May 2026

This August, I am taking part in the Great Cycle Challenge to fight kids' cancer! I’ll be riding in honour of my mom also.

Why? My mom had non small squamous cell carcinoma and passed November 27, 2013.

It saddens me that right now, over 1,400 children are diagnosed with cancer every year, and it's the biggest killer of children from disease in Canada.

Kids should be living life, not fighting for it.

So I am raising funds through my challenge to help these kids and support SickKids Foundation to allow them to continue their work in developing treatments and finding a cure for childhood cancer.

Please support me by making a donation to give these kids the brighter futures they deserve.

Your support will change little lives.

Thank you and stay safe!
