History

Dr. J.M. Denison S.S. is named after Dr. John Michael Denison. 
 
Dr. Denison was a witty and ambitious doctor who was much loved and respected in and around the Newmarket area. His generosity and outstanding work with teenagers inspired the community to name the school after him, an honour seldom bestowed on a living person. 

Our school mascot is the Husky.
