John Rocco ‘Dee’ DeChellis, 76, passed away unexpectedly on February 2nd, 2025, at his residence in Rochester Township. He was born in Rochester on March 9th, 1948. John’s life was marked by dedication to his family, service to his country, and a passion for community involvement.

John’s early years were spent in the close-knit community of Monaca where he was raised by his late parents, Fiore and Mary (Carducci) DeChellis. He was a proud 1966 graduate of Monaca High School, where he showcased his athletic spirit on the football field. His academic journey continued as he earned a Bachelor of Science degree and an MBA from Robert Morris University, equipping him with the knowledge and skills that would define his professional path.

In 1967, John married his high school sweetheart, Shirley J. Witherow DeChellis, and together they embarked on a 51-year journey of love and partnership until her passing on October 14, 2018. John was also preceded in death by his sister, Rita Binkoski.

John’s commitment to his country was evident when, in 1968, he entered the U.S. Army during the Vietnam War. Serving abroad as a sergeant, he displayed leadership and courage, qualities that would later influence his civilian career as a Superintendent at Horsehead Corporation.

A man of faith, John was a member of St. Cecilia Catholic Church in Rochester.

John’s pride and joy were his children and grandchildren. He is survived by his loving daughter and son-in-law, Melissa ‘Missie’ (Marvin) Leonard of Enon Valley, and his son and daughter-in-law, Jon-Paul (Karen) DeChellis of Spring Hill, Tennessee. He is survived by his grandchildren, Antonio DeChellis of Oxford, Mississippi, Gianna and Natalia DeChellis of Spring Hill, Tennessee, and his grand dogs, Abby and Jax and several family members.

An active figure in youth sports, John coached football, baseball, and basketball in Rochester, endearing himself to many young athletes and their families. Known as ‘Chef Pappy,’ he found joy in cooking and baking, delighting those around him with his culinary creations. His love for M&M candies was well-known, as was his enjoyment of travel, with many cherished trips to Florida, the Bahamas, Las Vegas and New Orleans with family and close friends.

John was a man who took pride in the meticulous care of his lawn, the serene beauty of sunsets, and the warmth of gatherings with loved ones.
