NEW YORK (AP) — An investor group lead by low-profile private equity honcho William Chisholm made headlines Thursday by agreeing to buy the Boston Celtics in a deal worth an estimated whopping $6.1 billion.
It will be the highest price ever for an American professional sports team if the deal is approved by the NBA’s board of governors this summer. So who is leading the charge? Here's what we know about Chisholm, 56.
In a statement released when the deal was announced, Chisholm said he grew up in the North Shore region of Massachusetts and is a lifelong, “die-hard” Celtics fan.
“I understand how important the Celtics are to the city of Boston — the role the team plays in the community is different than any other city in the country," he said.
He went to school in the Northeast, too. He received a B.A. from Dartmouth College in Hanover, New Hampshire. He received his MBA in strategic management from The Wharton School in Philadelphia in 1996.
In 2002, Chisholm co-founded Symphony Technology Group, based in Menlo Park, California, which specializes in tech investing — in particular data, software, and analytics companies. During his tenure STG, where he serves as managing partner and chief investment officer, bought and combined tech companies McAfee Enterprise and FireEye to create the cybersecurity company Trellix in 2022. STG also acquired Survey Monkey-parent Momentive.
As of 2023, the company has raised nearly $10 billion across its private equity investment funds and has completed more than 100 investments. In 2023, STG closed on its seventh and largest fund, raising $4.2 billion.
Before STG, he had stints at consulting firm Bain & Co. and investment bank PaineWebber, and he co-founded risk consultant The Valent Group.
He and his wife Kimberly have three children. While STG is based in the Bay Area, he reportedly has a house in Nantucket and plans to buy a house in Boston as well.

LOS ANGELES (AP) — The high-profile private attorney for Nick Reiner resigned from his case Wednesday for reasons he said he could not reveal, and he later told reporters that under California law his client is definitely not guilty of murder in the killing of his parents, Rob Reiner and Michele Singer Reiner.
“Circumstances beyond our control and more importantly circumstances beyond Nick's control have dictated that, sadly, it's made it impossible to continue our representation,” lawyer Alan Jackson said as he stood with his team outside a Los Angeles courthouse.
But, Jackson added, after weeks of investigation, “what we’ve learned, and you can take this to the bank, is that pursuant to the laws of this state, pursuant to the law of California, Nick Reiner is not guilty of murder. Print that.”
Jackson would not specify what he meant and took no questions at the brief news conference, but it was the first direct statement from a Nick Reiner representative about his guilt or innocence in the 3 1/2 weeks since the killings.
He spoke after a hearing where Reiner was supposed to be arraigned and enter a plea to two charges of first-degree murder. Instead, after meeting with the Judge Theresa McGonigle in chambers, Jackson, at his own request, was replaced by a public defender and the plea hearing was postponed to Feb. 23.
Jackson said that for legal and ethical reasons, he could not reveal why he had to resign. He first appeared in court representing Nick Reiner at a hearing a few days after the beloved actor-director and his wife of 36 years were found dead with stab wounds in their home in the upscale Brentwood section of Los Angeles. Jackson did not say how he was hired — or who hired him. Generally, defendants use public defenders when they can't pay for a private attorney.
Jackson has become one of the most prominent defense attorneys in the nation in recent years after his defense of clients including Harvey Weinstein, Kevin Spacey and Karen Read at her intensely followed trials in Massachusetts.
Deputy Public Defender Kimberly Greene took over as Reiner’s attorney during the hearing.
“The Public Defender’s Office recognizes what an unimaginable tragedy this is for the Reiner family and the Los Angeles community,” LA County Public Defender Ricardo D. Garcia said in a rare public statement on a case from the office. “Our hearts go out to the Reiner family as they navigate this difficult time. We ask for your patience and compassion as the case moves through the legal process.”
A Reiner family spokesperson said in a statement after Wednesday’s hearing that “They have the utmost trust in the legal process and will not comment further on matters related to the legal proceedings.”
During Wednesday's hearing, Reiner stood behind glass in a custody area of the courtroom wearing brown jail garb and with his hair shaved. Two deputies stood behind him. Jackson and his team stood in front of him on the other side of the glass. At one point, Reiner stood on his tiptoes to peer over the lawyers’ heads to look at the audience. He spoke only to agree to the delayed arraignment.
McGonigle approved the use of cameras inside the courtroom but said photos and video could not be taken of the defendant. Reiner did not wear the suicide prevention smock he had on at his initial court appearance on Dec. 17.
Reiner, 32, the third of Rob Reiner's four children, has been held without bail since his arrest hours after his parents were found dead on Dec. 14.
Jackson, a former LA County prosecutor, had given no indication of the plans for his defense.
He said that just hours after Nick Reiner’s arrest, he and his team were in New York when they got a call about representing him. He did not say who called him.
“We dropped everything,” Jackson said. “For the last three weeks, we have devoted literally every waking hour to protecting Nick and his interests. We’ve investigated this matter top to bottom, back to front.”
He said they remain “deeply, deeply committed” to him and said, “We’re not just convinced; we know that the legal process will reveal the true facts.”
Rob Reiner, 78, and Michele Singer Reiner, 70, were killed early on the morning of Dec. 14, and they were found in the late afternoon, authorities said. The LA County Medical Examiner said in initial findings that they died from “multiple sharp force injuries.” A court order has prevented the release of more details. Police have said nothing about possible motives.
Prosecutors have said they have not yet decided whether to seek the death penalty for Nick Reiner.
Rob Reiner was a prolific director whose work included some of the most memorable and endlessly watchable movies of the 1980s and ’90s. His credits included “This is Spinal Tap,” “Stand By Me,” “A Few Good Men,” and “When Harry Met Sally ...,” during whose production he met Michele Singer, a photographer, and married her soon after.
A decade ago, Nick Reiner publicly discussed his struggles with addiction and mental health after making a movie with his father, “Being Charlie,” that was very loosely based on their lives.
This story has been corrected to reflect that Nick Reiner is the third of Rob Reiner’s four children, not the youngest.
