Colin Campbell is joining the NHL Players' Association, but the league's disciplinarian hasn't gone to the other side.

Don Fehr, the NHLPA executive director, announced Monday the addition of Colin A. Campbell, formerly of MKTG Marketing, as director of corporate sponsorships.

Robert DeGregory and Maria Dennis have joined as associate counsel, while Richard Rodier has been retained as a lawyer and economic consultant.

"Each of them brings experience and skills that will be of benefit to the players as we go forward," said Fehr of Campbell, DeGregory and Dennis in a statement released by the NHLPA.

Campbell arrives from the West Coast, where he was general manager and vice-president of MKTG Marketing's office in Los Angeles.

The graduate of Acadian University in Wolfville, N.S., will work with the NHLPA's business partners and help grow the union's sponsorship business.

DeGregory's primary responsibility will be working on a full range of collective bargaining and individual player matters. A graduate of McMaster University in Hamilton and Harvard Law School, he has been senior counsel for the Writers Guild of America West, an attorney for the United Steelworkers International Union, and a law clerk for a judge of the U.S. Court of Appeals.

Dennis brings her expertise in the courts to the NHLPA following an outstanding athletic career. Like DeGregory, she will work on collective bargaining and individual player matters.

Dennis is a graduate of Yale University and Georgetown University Law Center. She is a former member of the U.S. women's national and Yale hockey teams, and has served on the board of USA Hockey, U.S. Olympic Committee and Salt Lake Olympic organizing committee.

Rodier possesses extensive experience analyzing the business side of professional hockey. He will assist the NHLPA in review and analysis of legal, economic and business issues affecting the sport.

Rodier is a graduate of the Wharton School of Commerce and Finance and University of Toronto Law School.
