Mary L. Haas

August 29, 1955 — September 30, 2023

Robinson Twp.

The beautiful beloved Mary L. Haas, age 68, of Robinson Twp., PA passed away peacefully surrounded by her children on September 30th, 2023.

Mary was born on August 29, 1955, as the youngest of five children. Mary was a vibrant spirit who relished conversing with anyone and everyone including her children, her friends, and any person who crossed her path. Mary was always impeccably dressed, enjoyed endless hours of shopping for everyone in her life, and had a fun sense of humor that made her easy to be around.

In her last days, Mary displayed an unbelievable amount of selflessness, strength, and most importantly courage. She was laughing and enjoying the company of those around her until the very end.

Mary was preceded in her death by her parents Joseph P. and Mary R. Viviano and her brother Joseph A. Viviano, Sr. She was survived by her four children Jennifer B. Pritts, William J. Beu, Michael R. Beu, Kimberly Beu-Wiemer, and her four grandchildren, Maria, Jack, Joseph, and Amelia.
