Pam Coleman, Office Administrator

It has been my pleasure to have been the Treasurer of Knox Presbyterian Church since February 2004. It was in December 2010 that I added ‘Secretary’ to that role, to become the Office Administrator.

I was born and raised in Kitchener, Ontario and moved to Listowel in 1998 after living in the Clinton/Seaforth and St. Marys areas.

My most important role is being mom to my 6 children, two daughter-in-laws, one son-in-law and Nanny to my granddaughter.  I have recently become a ‘dog person’ with the addition of three Golden Retriever grandpuppies and I enjoy cooking for my family and reading in my spare time.
