Serafino Ruffolo began his design career in Toronto in 1962 working in several architectural and construction firms over the years. In 1978 he decided to go it on his own and established Dero Associates, working out of his North York home. In 1983 Dero Building Designs Consultants Inc. was created and moved into their first offices. Then in 1990 Dero moved offices to their current Richmond Hill location.
