He has also been an occasional guest lecturer in 3D design for numerous institutions. He served on the Council of the RWA from 1984 to 1986 and has been a member of the selection committee for the annual exhibition. Dennis is a life member of the Bristol Savages (a society of artists) and has been president three times between 1973 and 1990.
He became a member of the Society of Industrial Artists in 1970 and was elected to Fellowship of the Chartered Society of Designers in 1986. His company and the design team he headed won various awards for 3D retail design nationally and internationally.
With one exception, he has shown his paintings at the RWA and the Bristol Savages annual exhibitions every year since 1963. He has also participated in many group and solo exhibitions.
Dennis’s painting and design skills are evident in the range subjects he covers and the equally broad range of styles and techniques he enjoys using to answer the creative concept.
He cites several influences on his work including James T. English RWA for standards in tonal awareness, Robert Hurdle RWA for life drawing, also Duchamp, Manet, Mondrian, Piper and Braque.
