Karen Elaine (Zimmer) Petley

Karen Elaine Zimmer Petley, age 75, passed away on November 15, 2025. She lived a rich and meaningful life across Ambridge, PA; Sewickley, PA; and Owen Sound, Ontario.

Born in Detroit, Michigan, Karen was the daughter of James Milton Zimmer and Anna Marie Zimmer and was raised in Beaver, PA. She was a graduate of Beaver High School and the University of Pittsburgh. She was preceded in death by her beloved husband, Michael John Petley.

Karen is survived by her children, Mark Petley (Casey Petley) and Emily Petley; her cherished grandchildren, Nora, Sophia, and Micah; and her siblings – the “three toads”, James Zimmer (Kathy), David Zimmer (Cindy), and Mathew Zimmer (Agnes).

A lifelong lover of the written word, Karen was both a devoted reader and a gifted writer. She was a regular patron of public libraries everywhere she lived and authored numerous articles for Shady Ave Magazine, as well as a book about Agnes Macphail. Her passion for literature was matched only by her deep love for her grandchildren. She found joy in taking them to cultural events and library programs, always encouraging them to explore the world with confidence and to believe fully in their potential.

The family wishes to extend their heartfelt gratitude to the amazing staff of Good Samaritan Hospice for their compassionate care, support, and dignity during Karen’s final days. A special thank-you is offered to longtime friend Martha Murdoch, whose kindness and presence were especially meaningful to Karen and her family.

A memorial service will be announced at a later date.

In lieu of flowers, donations may be made in Karen’s honor to the Iron Horse Theatre to support a scholarship established in her memory. Donations may be directed to: ironhorsetheatre@yahoo.com
