Kekäläinen began his hockey career in his native Finland, playing for four years in Finland with a number of teams as well as for Finland in the 1986 World Junior Ice Hockey Championship. Kekäläinen then played for the Clarkson Golden Knights for three years, establishing himself and gaining interest from professional teams. In his second year with the Knights, he scored 44 points in 31 games and was named to the ECAC Hockey League first all star team. In his third year with the Knights, he scored 18 points in eight games before signing with the Boston Bruins. Kekäläinen played parts of two seasons with the Bruins before returning to Finland, where he played for another two years. For the 1993-1994 season, Kekäläinen went back to North America, where he signed with the Ottawa Senators. He played briefly with the Senators that season, playing in 28 games. The following season, Kekäläinen played in Sweden before retiring in 1995 because of knee problems which were caused by injuries.
Executive career
Immediately after retirement Kekäläinen became involved with front officework in many capacities. He was General Manager of IFK Helsinki in the Finnish Elite League from 1995 to 1999, during which time IFK won one Kanada-malja and finished as the runner-up to TPS the following year. During this time with IFK, Kekäläinen also worked in several capacities with the Ottawa Senators. After he left Finland in 1999 Kekäläinen became director of Player Personnel of the Senators until 2002. While with the Senators he helped in picking future NHL stars Marian Hossa, Martin Havlat and Ray Emery. In 2002 Kekäläinen joined the St. Louis Blues as assistant general manager and director of amateur scouting, where he helped draft much of the core of the team in the early 2010s, including defenseman Alex Pietrangelo and forwards T. J. Oshie, Patrik Berglund, David Perron, and David Backes. After being passed over for the Blues' general manager job, Kekäläinen returned to Finland to take the general manager job with Jokerit. While with Jokerit, Kekäläinen had an unwritten escape clause with ownership that permitted him to leave if he was offered a general manager job in the NHL. That opportunity came on February 13, 2013, when after Scott Howson was fired the previous day, the Columbus Blue Jackets' president of hockey operations John Davidson, under whom Kekäläinen had worked while with the Blues, hired Kekäläinen to be the new general manager of the Blue Jackets. As a result, Kekäläinen became the first European general manager in the National Hockey League.
Personal life
Kekäläinen studied marketing at the University of Tampere and graduated as M.Sc. in 2000. He was selected as the alumnus of the year in 2018. Kekäläinen's family consists of his wife and two daughters.
