Mary Margaret Dennison passed away on January 13, 2019, at the age of 75.
She was born in Wilmington, Delaware on December 16, 1943, to the late Vincent (Gummy) and Margaret (Dolly) Concordia.
Mary was a beloved wife, mother, grandmother, sister and friend.

She spent many years volunteering her time as President of the Ladies Auxiliary for the local little league and was instrumental in various community fundraising efforts. Her attention to detail and organization skills proved useful in her fundraising efforts. She truly enjoyed spending time at her condo on the Jersey shore with her family. They would play endless games of gin rummy, stroll the boardwalk and enjoy time by the ocean. Later in life, Mary decided to work in the retail industry with Strawbridge and Clothier. She held positions in both accounting and sales. She enjoyed the camaraderie of her co-workers and her willingness to assist others was always appreciated.

Mary enjoyed spending time with her grandchildren down the shore, watching sports, and maybe most of all taking them shopping. She loved the Christmas season and was happiest watching her family open the gifts she had carefully selected for them. Her passion for design and perfection were evident in the meticulous detail of her Christmas trees and home during the holiday season.

She was preceded in death by her husband of 46 years, John J. Dennison. Mary is survived by her sons: John Vincent Dennison (Carol) and Matthew James Dennison; her grandchildren: Brittany Vari (Andrew), Brooke Dennison, Christopher Dennison, Mark Dennison and; her sister: Donna DeLillio (Anthony); and nephews Vincent and Anthony. And a special thanks to Danielle Cantlin for assisting Matthew as her caretaker.
