Everleigh is the youngest member of our team and began coaching at just 3 weeks of age. You will often find her riding in a backpack carrier on her mom (Coach Marissa) during classes or crawling around the mats and drilling during open mat. She helps to demonstrate movements and coaches at tournaments. While she hasn't earned any belt levels yet, she will surely let you know what she thinks of your technical abilities by the look on her face. When Everleigh is not managing the gym she enjoys spending time with her "doggie" and "cats"

Pete Mantel

-Head Judo Coach

-6th degree Judo Black Belt (2018)

-United States Judo Association President








Peter Mantel started judo in 1975 at Lee's Judo Club in Pacifica, CA at the ripe old age of 6, and never stopped. He competed almost every weekend and grew to love it. His parents would not let him play football or baseball, yet allowed him to get thrown on his head repeatedly.

Pete joined the US Coast Guard in 1986 and continued his judo career at Santa Rosa Junior College under the direction of Terry Kelly. He was eventually connected with Phil Porter who ran the National Judo Institute in Colorado Springs, CO. Pete was the first active duty Coast Guard member to be stationed in Colorado specifically training for the 1992 Olympics. Although he did not make the team, he was asked by 1988 Olympic Medallist Lynn Roethke to be her training partner for the Barcelona games.

Pete was transferred to Long Beach, CA where he was stationed aboard ship and trained in Vladivostok, Russia during a patrol. He trained briefly with Hayward Nishioka at Long Beach State.

Pete ended up back in the Bay Area in the mid 90's where he trained with Terry Kelly again and began coaching other athletes with great success. He is credited with training an elite athlete who was ranked in the top 5 of the USA.

He also trained, coached and competed in San Diego, CA with Gene Mauro and fought in the Master's World Championships in Londonderry, Ireland in 2002. He took a gold medal at the Master's Goodwill Games in Mississigua, Canada as well.

Pete ended up in Virginia in the summer of 2003 where he stood up the Coast Guard Judo club in Yorktown, VA. He trained with a team of 8-10 with magnificent results. He coached and competed in many local, state, regional, national and international events for almost 10 years. He coached an elite athlete from a white belt in just 2 years and led a team of strong fighters to place in every tournament they competed in.


Pete’s personal competition highlights include:

2005 US Senior Nationals Master's division-Bronze

2008 US Senior Nationals Master's division-Silver

2008 Continental Crown Senior's division- 5th

2009 Fall Classic and National Ladder Tournament- Gold
