In retirement, he continued working at Franklin Sussex Auto Mall.
Peter was a devoted member of Sussex Christian Reformed Church, where he served the Lord and his church family in many capacities throughout the years. He also faithfully served on the board of Sussex Christian School, reflecting his deep commitment to Christian education and to passing on a legacy of faith to future generations.
Above all else, Peter treasured his family.

He was also blessed with 19 grandchildren and 2 great-grandchildren, each of whom brought him great joy. He is also survived by his siblings, Margaret Kuiken, Lorraine Hagedoorn, and Gerry Thiessen.

Peter will be remembered for his quiet strength, faithful spirit, servant’s heart, and enduring trust in God.
