Mary E. Cavallo

November 26, 1930 - November 17, 2023

Mary E. Cavallo of Williamsburg, Virginia passed away peacefully at the Sentara Williamsburg Regional Medical Center on November 17, 2023. She is preceded in death by her parents Michael A. Cavallo Sr. and Sara Cozza of Chicago.

Mary was born on November 26, 1930 in Chicago, Illinois and years later graduated from Lucie Flower High School in that city with an interest in medicine that she pursued successfully her entire life. Mary earned her MT (ASCP) at the Wesley Memorial Hospital School of Medical Technology in 1953. She later earned a B.S. at Roosevelt University, Chicago (1977) to keep pace with her profession as it entered the age of computer science. Her urge to learn never stopped and when she finally joined Northwestern Memorial Hospital her responsibilities grew quickly from Technologist to Supervisor roles in four major laboratories within that large hospital!

When her 40 year career in medicine finally ended, it was time for Mary to retire and she moved to Williamsburg to join her younger brother, Michael Jr. and his wife, Mary, here in Williamsburg. Here her activities centered around her nieces, Pamela, Patricia, & Susan and their 8 children. Mary was also an active member of The Williamsburg Methodist Church, and a lover of five dogs that over the years have filled her life. She has many friends here in Williamsburg who can join our family in a celebration of life service at Bucktrout of Williamsburg on Friday, December 8th at 1:00 pm.

In lieu of flowers please donate to the Heritage Humane Society in memory of Mary E. Cavallo.

    Mary and I worked together, lived together, traveled together, and spent many good times together over the years. Distance separated us the last years but we still talked and laughed on the phone frequently. Recently she told me she was eating a bear claw Of course I had no idea what she was talking about. This was one of one of our last laughs together.

    Will never forget the first time we met as Ms. Cavallo became Aunt Mary. Absolutely blessed to have spent time and created meaningful memories with her. Aunt Mary was an accepting, inviting and loving woman. She is missed, however Heaven has become a better place.

    Words cannot express how much I adored my Aunt Mary. All 3 of her neices( myself, Tricia and Susan) would fight over who would sleep with her when we came to visit. She was instrumental in guiding me towards a healthcare profession. I used to love going into work with her when she worked at Northwestern hospital as a Chief Medical Technologist. She was respected by many in her work and social circles. I know she is happy to be reunited with her loving parents and dogs! I will miss you everyday Aunt Mary.❤️

    Mary was a kind neighbor and not afraid of adventure. As newcomers to Williamsburg in 2022, John and I moved into a house opposite Mary's house. Mary and Val decided to go and watch a movie at the Kimball theater on Duke of Gloucester street. It was an Indian saga which lasted for 3 hours, which we did not expect. Fortunately we had visited the Candy shop beforehand and the chocolates we bought sustained us through the movie. We enjoyed laughing afterwards when we talked about it.

    As one of Mary’s goddaughters, I had the pleasure of traveling to Kansas with her one spring. We spent most of the time on the plane trying to figure out how fast a plane flies. We knew we were going about 500 miles to our destination and that the trip was one hour long. When it suddenly dawned on us how simple the solution to this was, we laughed and laughed! Mary enjoyed a good laugh! Just one quality that made her so lovable.
