MITCHELL SISLE

Mitch passed away peacefully on March 30, 2022 at the age of 84, exactly two years after his beloved wife of 60 years, Roz, passed away. He is survived by his brother Stuart Sisle and wife Anne, sister-in-law Sheri Sisle (wife of his brother Norman who predeceased him), sister-in-law Marilyn Karp (sister of Roz), children Ellen Sisle and husband Ken Schotsch of Philadelphia, PA, Larry Sisle and wife Stephanie of Annapolis, MD, and Sharon Pinard-Sisle and wife Melissa of St. Johnsbury, VT, and his six grandchildren, Jacob Anderson, Collin Anderson, Joey Sisle, Caleb Anderson, Emma Schotsch, and Kaia Anderson, as well as nieces, nephews, cousins, and their families. Born on December 23 in New York City, he was the son of Joseph Sisle and Sylvia Sisle Schmier, both of whom predeceased him, as did an infant son.

Mitch received his BSEE with honors from Lehigh in 1959 and an MSEE from Drexel University in 1962. In 1961 he married Roz. The two of them first lived in Camden, NJ and then moved to Massachusetts. In 1964 they bought their first house in Framingham, MA, where they raised their three children and formed many life-long friendships. Mitch was a brilliant engineer who spent his career with Raytheon. An author of a number of papers and articles as well as a holder of patents, his most significant technical accomplishment was having developed Raytheon's PATRIOT Guidance Test and Simulation Facility in 1971. He always was quick to share that the PATRIOT missile was intended for defensive purposes to intercept other weaponry. It was not a surprise to learn that he even discussed this with the nursing staff at Horsham Center for Jewish Life, where he spent the final 21 months of his life. Mitch had an innate sense of how everything worked and how everything was put together. He could fix anything � watches, stereos, household appliances, cars � and he could build anything � toys, cabinets, decks, porches, and even houses. His largest project was a vacation home in Barnstead, NH where the family spent many summers relaxing by the lake. In 1999, Mitch was elected Fellow of the Society for Modeling and Simulation, International (SCS), and he served on the Lehigh University Alumni Board as Regional Vice President for a number of years.

Once Mitch retired, he and Roz briefly relocated to San Diego, CA and then in 2002, more permanently to West Palm Beach, FL, where they spent 18 years together before Roz tragically died of COVID early in the pandemic. In their Valencia Shores community, the two of them enjoyed the warm weather and a robust social life in the company of close friends and visiting relatives. It was here, in the last 15 years, with a quiet stoicism, that Mitch met the challenge of living with Parkinson's, a disease that slowly robbed him of his physical independence and dampened many of the plans that he and Roz had made for this time, particularly for travel. Until he no longer was able, the two of them took many pleasure trips within the United States and abroad.

Mitch was proud of his adult children's accomplishments and delighted yet more so in keeping track of what his grandchildren were doing. As Parkinson's increasingly impacted some of his cognitive abilities, he still always remembered and was up to date on the details of their lives � what sports they were playing, and where they were living, working or studying � including telling a speech pathologist on what would be the last day of his life that his grandson's fiancee shared the same profession.

Both Roz and Mitch were giving of their time to numerous causes and volunteering was an important part of their lives together. While Roz often worked with organizations that supported children, Mitch used his construction skills to help others, whether this meant building playground equipment, furniture and built-ins for family, friends, and synagogues, or most significantly, houses with Habitat for Humanity. Although quiet and never perceived as a people person, he was compassionate, kind and caring, and always willing to assist anyone in need. His life was defined by hard work and a sense of responsibility. He was unassuming but made a significant impact on those around him. As we did two years ago when Roz passed away, the world lost another wonderful human being when Mitch died.

Funeral services to be held at Goldsteins' Rosenberg's Raphael Sacks, 310 2nd Street Pike, Southampton, PA 18966, are scheduled for Sunday, April 3rd, at 1:30 PM. They will conclude around 2:15, at which time there will be an approximate 25 minute procession to Montefiore Cemetery, 600 Church Road, Jenkintown, PA, 19046. The burial service will commence at 3:00 PM. Donations in his memory may be made to Habitat for Humanity, www.habitat.org
