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

She was born in Detroit, Michigan on February 24th, 1950, the daughter of James Milton Zimmer and Anna Marie Zimmer. She 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). She was preceded in death by her beloved husband, Michael John Petley.

Karen was raised in Beaver and was a graduate of Beaver High School and the University of Pittsburgh. She was a lifelong lover of the written word who 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 for Karen will be announced at a later date. Arrangements have been entrusted to Alvarez-Hahn Funeral Services and Cremation, LLC, 547 8th Street, Ambridge.

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.
