BRENTWOOD — Erin Merrill doesn't skip a beat when asked how many people saw her daughter Georgia honored by the Boston Celtics this past Friday night.

"There were 18,641 people in the room," Merrill said, adding, "I asked her if she wanted me to go with her, and she said no."

Georgia, 9, was honored by the Celtics as part of the organization’s "Heroes Among Us" initiative. The team recognized her because of her efforts with the "Peach Project," a charity she founded as a second-grader. The Peach Project produced a holiday play, "A North Pole Story," on Dec. 14, raising more than $5,000 for One Mission, a Boston nonprofit helping children with cancer and their families.

Erin Merrill said her daughter got the attention of the Celtics after they requested a donation of tickets for their holiday play, which included a raffle. The Celtics did donate a set of game tickets and a ball signed by all the players for the raffle, but they also emailed Merrill the Friday before the show, announcing Georgia's selection as one of their heroes.

Merrill explained that the Celtics honor one hero from its local communities during each home game. There are 41 home games this year, she said, and Georgia is one of 41 honorees spread out over New England.

The Heroes program is co-sponsored by the Massachusetts State Lottery and was started in 1988.

Merrill said a Celtics staff member saw the request for donations and researched the Peach Project and its founder. "They were so impressed, they upgraded the seats they were giving us, to two rows behind the bench," Merrill said.

According to a Celtics press release, Georgia was specifically honored for her work for the New Hampshire Food Bank. She has raised more than $13,000 and fed 9,000 individuals with her efforts, according to the release.

At TD Garden Georgia was treated like a queen, and her family, including two brothers, as a royal entourage. They arrived a half hour early, admitted to a special back entrance, and were able to go on the court and watch the warm-up, Merrill said. Former player Cedric Maxwell posed with the family for pictures. The Merrills had courtside seats, but only for four, so Erin Merrill sat in the bleachers with extended family members. But she could still see everything.

Georgia was invited on the court at the end of the first quarter. "She went out by herself and did a 360-degree wave," Merrill recalled. 'They put her picture on the Jumbotron."

Her two brothers, Owen, 11, and Miles, 6, are huge Celtics fans "and were thrilled," Merrill said.

And the Celts beat the Dallas Mavericks that night, 114 to 93.

"I think it's amazing," Merrill said of her daughter's philanthropy. "She has these ideas, and we do the best we can to help."

Georgia has been looking out for the needs of others since second grade, when a homeless man glimpsed at the side of the road inspired her to collect canned food for the New Hampshire Food Bank. The Peach Project was born that year. In third grade, she made button bracelets and sold them online to benefit the Food Bank, and this past December she and her family put on the show, which included an original play, children caroling, the raffle and a visit from Santa.

The evening of entertainment in Grace Ministries International raised $5,200, Merrill said. Donations were still coming in last week, she said, and she mailed the final check Monday.

Though her mother characterizes her as shy, Georgia said she wasn't afraid when she went out on the basketball court, and that it was, in fact, her favorite part of the evening.

And she's not done yet. Though her projects have traditionally been during the holiday season, she's brainstorming with her family and, "We might do something in the summertime this year," she said.
