Waltham Boxer Is 2X National Champ

Waltham boxer Lauren Migliacci, 35, is a national champion for the second time after winning at a competition a few months ago. She’s now ranked #1 as a Super Heavyweight.

The Olympics aren’t on the horizon quite yet, but she’s a star in a local boxing community that is growing—and has plenty of Waltham connections.

“Powerful, Aggressive”

Back in November, Lauren defeated North Carolina boxer Amanda Jenkins in the 178+ lbs weight class during a bout at the 2023 USA Boxing National Championships in Lafayette, Louisiana.

“The competition was tough,” she said. “It went all three rounds.”

Lauren won another national title in Detroit earlier in the year. She’s now 10-2 as a Super Heavyweight, with refs stopping the bouts four times.

She trains at Boston Boxing in Brighton. Waltham native Ed LaVache, himself a former fighter, has owned the gym for 18 years.

Ed trained another top Waltham boxer, Tommy Duquette, a contender who was ranked second in the country and was at Olympics trials twice. But Lauren is his first national champ.

“She pushes herself really hard,” Ed said. “And she pushes her team really hard.”

Team Boston Boxing

Oddly enough, when Lauren first arrived at Boston Boxing five years ago, she only wanted to get in shape. Boxing was not in the cards.


“I wanted nothing to do with it,” Lauren said, laughing. But Ed noticed her power right off the bat.


Gym members encouraged her, eventually convincing Lauren to get in the ring to spar with a variety of Boston Boxing women and men.

One of them is Viondy Merisma (WHS ‘09), a former high school star athlete who had played some preseason games with the Tennessee Titans, then in various football leagues.

Viondy holds back with Lauren, but sparring with him, even at 50%, elevates her training above what she can get with the women at Boston Boxing. 

The other training is just as intense, involving running, weights and drills.

Ed said Lauren has won at competitions by adding better defense and technique to her raw power. But Lauren defers credit.

“I do it for Team Boston Boxing,” she said. “We have probably the best, most elite competitive women in New England, if not nationally.”

And it’s not just her gym. She also works with fighters from Nolan Bros. Boxing and Fitness on Sun Street in Waltham and other gyms.

“We truly have some amazing female representation at the national level from New England,” Lauren said.

Next Steps?

By day, Lauren loves her job as a chief of staff for Oofos, the Braintree-based recovery footwear company. 

Last year she married Sid Diaz-McCree, a DJ and function planner who operates small businesses in Waltham. They bought a house in Waltham in 2018 and have friends in Waltham Police and Fire.

So are the Olympics in her future? Some of the competitions she’s won involved qualifiers for Paris 2024.


Unfortunately, Lauren’s super heavyweight class is not offered currently, and four more years puts her closer to 40. But there’s still plenty of fight left in her.

“We’re going to keep on fighting in the nationals and see how many titles she can win,” Ed said.
