Learn a discipline at this dojo and become part of a community
Published at | Updated at
REXBURG — A local dojo offers multiple disciplines, including Brazilian jiu-jitsu, karate and judo. It’s a place where all ages are welcome, and anyone can join and become part of a community.
Mamoru Martial Arts, owned by husband-and-wife team Alexander and Erica Greenfield, has two locations, including Rigby and a newly built state-of-the-art facility that’s on farmland in Burton. It opened over the summer near Burton Elementary School.
“We have a ton of space and really high ceilings. It’s just a great place for the parents to sit and watch. It’s big enough so we can have different sports going on at different times,” Alexander said. “I’m pretty psyched about it.”

The business has been around for six years. It teaches kids starting at 2 and a half years old.
“The oldest person in the dojo is probably 81 years old,” Greenfield said. “We have about 100 students across all the different disciplines.”
Besides Brazilian jiu-jitsu, karate, and judo, there’s also women’s self-defense, fencing, Muay Thai, MMA, wrestling, taekwondo and yoga.
“It’s really been a blessing. We’ve got about 10 instructors throughout. We keep our prices low,” he said. “I don’t want anyone to be priced out. If anyone is ever in a situation where they think they want to do it but they can’t afford it, please have them reach out to us.”

The dojo has given scholarships before. Click here to learn more about the classes, schedules, and prices.
During the day, Greenfield teaches as the head of special ed at Farnsworth Middle School in Rigby. At night, he is actively pursuing his doctorate in educational leadership, while also running a business. He is the founder of Rigby Free Soccer.
He began judo as a kid at 9 years old in New York, where he’s from.
“There’s a very strong Japanese judo community. Our area has sent a lot of people to the Olympics. I trained with many Olympians. One of my senseis was an Olympic coach,” Greenfield said.
He was exposed to several sports growing up and loves judo and Brazilian jiu-jitsu.
“I like that they are aerobic and weight-bearing. As you get older, it’s important for our bone density to do some weight-bearing exercises,” he said. “There’s a lot of camaraderie. You get to know people. It’s so fun. It’s a blast.”

Mamoru Martial Arts started in 2020 when Greenfield said he felt spiritually prompted to return to judo during the COVID-19 pandemic. His dad became his first investor and bought the dojo’s initial mats.
“I think it’s important for people in general to exercise. It’s good for the mind and body. For better or for worse, I think it’s important to know how to protect yourself. I personally think one of the best ways to be able to protect yourself is to be heart healthy,” he added.
“Mamoru” means protector, which, according to the website, reflects the school’s mission to help students build confidence, discipline, and meaningful connections. What began as a pandemic impression has now become a thriving community, Mamoru Martial Arts online says.
“It has been wonderful to meet so many cool people from different walks of life and seeing them socializing with one another, even outside of the dojo. It’s very rewarding. That’s just a really good feeling,” Greenfield said.
