Starting in 1989, McClennen worked as a freelance artist at his own company, Spire Art & Design in Ontario, Canada. Much of his research during that time had been in silicone gel-filled prosthetic appliances with emphasis on natural tissue movement, achieving hyper-realistic results.
Four years of classical education in figurative sculpture at the Ontario College of Art & Design and specialized training in forensic art led Jay to recreate the human form in the varied, but related fields of film, forensics and medical prosthetics.
In the Hollywood film industry, Jay worked for 17 years with Gordon Smith, President of FXSmith. The team received Emmy and Hollywood Make-up Artist Guild nominations and won Gemini and Saturn Awards. With his skill in forensic facial reconstruction, he provided an invaluable service to the Ontario Coroner’s Office, local law enforcement, and the Ontario community by assisting with unidentified human remains.
Jay’s work on medical prosthetics involved the exploration of new methods and materials for facial and limb prostheses while making advances in custom breast designs. Jay led and completed a two year clinical trial at the Toronto Sunnybrook Regional Cancer Center on an innovative custom silicone breast prosthesis of his own design.
He has co-authored publications regarding his unique breast prostheses in the Current Oncology Journal and osseointegrated facial prosthetics in the Journal of Otolaryngology Head and Neck Surgery. Jay continues to lecture internationally on a variety of topics demonstrating his advancements in the field of anaplastology.
Jay served as an active member and President (2013-2014) of the Board of Directors for the International Anaplastology Association (IAA).
