Peacefully, on Sunday February 18, 2018 at Pioneer Manor in Sudbury at the age of 82. Dennis was the beloved partner of the late Agnes VanBetlehem. Loving father of Bob Tappenden (Jo) of Sault Ste Marie, and Lisa Cameron of Sudbury. Dear step-father of the late Alice Diotte (Richard) of Sudbury, Helen Mullenix (David) of Kincardine, Frank VanBetlehem (Jacqui) of Oakville, Linda Semple (Phil) of Etobicoke. Dear brother of Edwin Tappenden (Sylvia) of Calendar, and Marilyn Perrin (Ralph) of Boswell, B.C. He will be dearly remembered by his grandchildren, great grandchildren, nieces and nephews. Sadly missed by his long-time friends Betty, Serge, Bob, Linda, Jackie, Helen, his many friends at TNT Auctions and his line dancing groups. Dennis retired from the Ontario Provincial Police in 1991 and will be remembered for his commitment to teaching safety at schools throughout the Sudbury District. Over the years, Dennis volunteered his time with many different organizations including; Drivers Education, Boy Scouts of Canada, Masonic Lodge, Sudbury Minor Hockey, French River snowmobile club, Sudbury Youth Services and Big Brothers. He ran for the P.C. Party in the Nickel Belt riding in 1980 and was the first Provincial Police Officer to seek election to public office. Dennis always had a positive outlook on life and a great sense of humour. Special thanks to all the caring and compassionate staff at Pioneer Manor. At Dennis's request there will be a private family service. Donations to the charity of your choice would be appreciated.
