Another returning name is Rob Hale, who was also a minority owner. He is the founder and CEO of Granite Telecommunications. He was complimentary of Chisholm after the sale was announced a few months ago and has been a known Celtics co-owner throughout the sales process.

The sale of the Boston Celtics has been finalized. An investor group led by private equity mogul William Chisholm took control of the NBA’s most-decorated franchise from a group led by Wyc Grousbeck that had owned the team since 2002.

The ownership group led by Bill Chisholm has officially taken control of the team, and circulated a release to that effect with the team Tuesday.
