My Story

Same stuff, different year, CANCER SUCKS!


I'm dedicating this year to a fellow Burlington Dad fighting cancer, Kevin Visser.

These kids with cancer need people like you to help them with their fight.

Please generously donate some cash this year.

I have and I will give my time to them if it helps.



My Challenge

  • Double billing by the GCC
    13 Sep 2022

    Another donor has brought to my attention that they were double billed for their donation. PLEASE PLEASE check your bank statement to check that you were not billed twice by The GCC and SickKids. Contact me at 905-580-3412 if you have any issue and I will work to get it resolved. Or email me at jgremmen64@hotmail.com. Thanks

    It’s with sadness that I tell you that Kevin Visser passed away yesterday. A friend in Burlington fighting hard against cancer with his family and friends by his side. He is survived by his wife Lisa and two sons Keo and Park. RIP dear Kevin. Peace.

    SickKids is lucky to have you as a support group. I have the best friends/family anyone could have!

    I’ve ridden a great deal this month and got Marcus to come with me on many of the long hauls. We have been hitting personal bests during the month (obviously culminating with our 100 mile/160km single day journey along Lake Erie from Simcoe, to Port Dover, Dunnville, Welland and Niagara Falls! Marcus is a great sport and willing companion. It has made for some great memories and “builds character” in Marcus’ words. During our ride we talked about school, home, food, work and the SickKids fighting for their lives. Marcus is a good, hardworking young man. Hopefully your donations and some kind thoughts will help these kids and their families through these hard times. Thanks again Guys!

    Thanks to ALL OF YOU!
