Dennis was born and raised for part of his youth in Rome, NY. He then came to live in Oswego, and attended both St. Paul’s Academy, and Oswego Catholic High School, from which he graduated in 1977. Dennis graduated from Chabot College of Hayward, Calif., with a degree in accounting.
He and Jane Kleinbach were married in Oswego on March 29, 1980. Thereafter, the young couple moved to Texas where he learned the trade of machinist. After the birth of their first daughter, Jessica, they moved back to Oswego, where a daughter, Kristin (Muppy) and a son, Nathaniel, were born.
Back in Oswego, Dennis began a career in nuclear power at James A. FitzPatrick Nuclear Power Plant where he started as an office worker, continued as a maintenance electrician, and retired as a licensed reactor operator. He was employed at the JAF Nuclear Power Plant (Entergy) for almost 30 years.
Throughout his life, Dennis worked hard and played hard. He was an avid motorcyclist and enjoyed motorsports, hunting, construction, woodworking and playing harmonica. He appreciated all types of music, but especially enjoyed the blues and was known to do an impromptu Elvis impersonation on many occasions.
He enjoyed coaching soccer and baseball teams as his children grew through the years. When he wasn’t coaching his kids, he was their greatest fan. Dennis would frequently say he was blessed with a wonderful life, surrounded by many friends and a loving family. His family was the center of his world. He was an extremely proud husband, father and grandfather.
He is survived by his wife, Jane (Kleinbach) Pacheco; and children, Jessica (Robert) Newson of Saratoga Springs, NY, and Kristin (David) DeGroff of Royal Oak, MI, Nathaniel Pacheco of Oswego; daughter-friend, Jennifer Cushman of Fredericksburg, Va.; and grandchildren, Cole and Allison Newson.
Dennis has donated his body to science, hoping to make a difference in the medical world, especially in the cures for cancer.
