    Guy was my ELI mentor for my first project at the high school. He was a great mentor and taught me so much about microbiology. I still use the skills I learned from Guy to this day in my undergraduate classes. I am so sorry for your loss, you are all in my thoughts.

    We were saddened to hear of Guy’s passing, and so sorry for your family’s loss. He was always friendly toward us, and always had a smile to give! We’re thankful Connor had the opportunity to have Guy as his soccer coach many years ago. Guy was a great coach and so patient with the boys on the team! Connor really liked him, as did we. Praying for your family during this difficult time.

    Hey pal. When we were young you did not hesitate to take me with you and your friends. Not too many older brothers want their little brother tagging along. It will never be forgotten. You left us too soon. Even though we did not keep too close contact, each time though was special. I am so proud of you and your lovely family. Mange takk for being the best brother one could ever have. I miss you and I love you.
