Dr. Guthrie was born and raised in Guelph. He attended  Canadian Memorial Chiropractic College in Toronto Ontario and while at CMCC, he was elected to council and won two Award of Merit recognitions.

Upon graduation, he established a successful practice in Collingwood for 8 years, a practice that still serves that community. Upon moving back home to Guelph he built the Guthrie Chiropractic Building located at 291 Victoria Rd N.

Walking, biking, CFL football (especially the Hamilton Tiger Cats), hockey (Guelph Storm), basketball (Toronto Raptors), and Guelph's own Lakeside Church are of great interest to him. He has served on numerous community boards and committees. He enjoys serving the community as a Guelph Chiropractor.

Married to his wife Karen, together they have two children and two grandchildren.
