Keith Green’s career began in the 1970s in the family business, Dundas Lock & Key, before founding DLK Security Systems in 1979. In 1986, he launched Temtronic Designs Inc., where he invented a thermostatic control system for commercial enterprises, monitoring heating and cooling systems in large buildings.
In 1992, Keith entered the publishing world, founding a custom publishing business at a time when email and the internet were transforming communications. During the 2008 recession, he successfully diversified his work, including mastering backup solutions.
Keith has demonstrated a longstanding commitment to community service. He served as a Dundas firefighter for 15 years and is a Paul Harris Award recipient and former active Rotarian in two different Rotary clubs. In 2007, he joined the Board of Directors at the Dundas Museum and Archives, later serving as President and Board Chair. He continues to volunteer there, maintaining the original Dundas fire trucks.
Keith spoke about his recent book, Into the Mystic, which is based on his mother’s life and stories. He shared a video of his mother recounting her own experiences working in the Secret Service — a powerful and personal moment for members. Keith explained that her stories inspired him to begin writing, blending real-life history with his love of mystery, puzzles, locks, and secret societies.
