Born in Fredericton, New Brunswick, O’Leary played ice hockey at St. Thomas University in his hometown of Fredericton. Upon graduation, he worked as a teacher in Alberta and later in British Columbia, while coaching the respective schools’ ice hockey teams. He then also worked in Hockey Canada’s High Performance Program at the U16 and U17 level.
In 2009, he accepted the position as head coach of the International Hockey Academy of Lower Austria in St. Pölten, Austria. During his time in Austria, O’Leary also served as head coach of the country’s U18 and U20 national teams.
He moved to Switzerland prior to the 2013-14 season, joining the coaching staff of SC Langenthal of the second-tier division National League B (NLB) as an assistant. When Olivier Horak stepped down in December 2014, O’Leary took over the head coaching job at SCL. In the 2016-17 season, he led the team to the NLB title, beating the SC Rapperswil-Jona Lakers in the finals. He parted ways with Langenthal after the conclusion of the season and was named assistant coach at National League A club Genève-Servette HC on May 19, 2017.
