BOSTON -- Danny Ainge attended the John Havlicek celebration of life at Trinity Church on Thursday, his first public appearance since suffering a heart attack nearly a month ago in Milwaukee.

But it wasn’t his first time around the team. When Brad Stevens was asked about Ainge after the service, he walked off saying he’s been around Ainge for two weeks now. That means Ainge is back in the office, going through potential draftee workouts and figuring out his next steps with the franchise.

“Danny’s a tireless worker,” Celtics co-owner Steven Pagliuca said. “We’re trying to make him slow down, but he seems very healthy and he’s on a plant-based diet, feeling good, and we’re just happy to see him back."

Ainge breezed past reporters as Stevens was saying a few word about the ceremony, refusing to talk and swiftly getting into a car. The 60-year-old’s heart attack was mild, and he was back in Boston just days after it happened. If Stevens’ two-week timeline is accurate, Ainge was back to work about a week later.

Boston has a lot of work to do this offseason. The NBA draft is June 20, and if Boston is going to swing a deal for Anthony Davis, it’s likely to happen by then so the Celtics can convince Kyrie Irving to re-sign. If that doesn’t materialize, Boston has to come up with a backup plan

“We’re really just going to go through the roster, the 15 guys, and say who’s here, should we move some of the guys, should we re-sign these people, what are we going to do," Celtics principal owner Wyc Grousbeck recently said. “It’s really like a new movie, with a new script, and in some cases a new cast. And hopefully a new ending.”

It’s a lot of work for Ainge, but after his second heart attack in 10 years, the priority is making sure he’s healthy.

“We want him to make sure he takes care of himself,” Pagliuca said. “He’s real excited about this next year.”
