Meet the Team

“The trainers, they believe in you more than you would ever imagine.  That’s the type of gym everyone needs to be a part of.”

-Yesenia Mendoza, JMBA Member

Our teams’ main focus is YOUR goal. We thrive on making each day a different workout, NO DAY IS EVER THE SAME! Our trainers have a collective 50 YEARS of experience in boxing, both competing and training, and some are still active today. We are well-versed in weight training and cardio exercises. Therefore, our boxing academy offers a variety of workouts that push you both physically and mentally.




I guarantee that after you train with me you will not only love the workout – you’ll love the sport of boxing.”

I am a veteran of 58 amateur boxing bouts and first began training boxers in 2006, working with adults and teenagers. I strive to help members stay healthy, lose weight, compete, build confidence, or simply learn the science of boxing. I work with a variety of clients – from 4-year-olds to 70-year-olds, average Joes, blue-collar, soccer moms, troubled teens, honor roll kids, amateur boxers, professional boxers, school teachers and everything in between. No matter who you are, I can cater training to each individual. I adapt to each client’s style and will modify workouts to accommodate injuries, weaknesses, strengths, dislikes, and likes so that everyone can learn how to box.



Never in a million years did I picture myself in a boxing ring! I wish I would have come across a boxing gym like this when I was overweight. It definitely would have helped me with my physical problems and I would have avoided all the mental drains that the bullying caused. Boxing definitely has built my confidence and has shown me things I did not even know about myself. It’s not just a workout – there are life lessons learned in the boxing gym.” 

Kelly was born and raised in Sacramento. As a kid, she struggled with obesity and was bullied about her weight. Weight loss has always been a struggle for her, but boxing has helped her not only physically, but also mentally. As a four-foot-ten, singing in the shower, Disney-loving 24-year old woman, she may not seem like someone you’d see in the ring or managing a boxing gym. However, she puts her Bachelor’s degree in Economics and 8 years of customer service to use and proudly proclaims to love her job.


Yesenia Mendoza

Yesenia aka Reno 911 is a Sacramento native who started at our gym as a member in 2018. Yesenia is big on being light-hearted & someone who always looks at the glass half full. Reno is a huge believer in self-care & the importance of keeping your mental health intact. Boxing has helped her maintain that for herself & strives to make every person that comes into the gym, feel the same way but with a smile on their face!  

“It all started as a post I saw on IG. I was going through a really difficult time in life & felt completely lost. I came across JMBA at the right time & I couldn’t be happier about my decision.  Since starting with JMBA, I lost over 40 pounds! 4 years later & now I officially am part of the team, even though I always felt like I was.”

“I want to contribute to communities that are making a real difference in people’s lives and the sport (ie. Warrior Program). I feel like I can do that here. “

“Be a fighter in your life! Grow through what you go through. Behind every strong person is a story that gave them no choice but to stop waiting for the light at the end of the tunnel and lit that darkness up and chose to rise.” 

Amy started boxing with us in 2017, initially just for fun. Then her interest in competing grew. At her first national tournament, she took on boxers with triple the experience. She came out glorious and won it all, being the first first national champion in Placer County. Amy began to assist Jose and David in coaching and now holds her own classes and private lessons. Many little girls look up to her- she is a great inspiration to us all.



In 2019, Levy came into our gym to check us out. He was quiet and humble, and we were surprised to learn he came from an extensive boxing background. Over time, Levy has become more outspoken and is excited to share his knowlege with members. Now with fourteen amatuer boxing bouts under his belt, he is coaching alongside Jose and David. He is currently on active duty in the United States Air Force.



Alex began boxing with us in 2018. A very hardworking and disciplined young man, Alex was able to graduate high school early. Now,  he is scouting what university he wants to attend. Currently, we are lucky to have Alex sharing his knowledge from his boxing experiences with the classes he now coaches.


“For anyone on the fence about working out, this is the place to start. The staff is absolutely amazing. I can’t say enough about how kind and helpful they are. The people that you workout with are nice and there’s a family atmosphere here. Even if you never thought boxing was for you, try it! I never thought I’d enjoy this as much as I do. It’s hard, but it’s so worth it.”

Amy Boryczko

“JMBA keeps me motivated and excited to work out and train. They have helped me set goals and stay on track. I love and appreciate the efforts of the staff and trainers. They help me reach my fitness goals.”

Azeeta Mott

“My sons have been going to this gym for two years now. They have come such a long way and they love to box and workout. The coaches are so encouraging and they have such a love for boxing it pours out of them and into the students. I thank them for being positive role models in my sons lives and making us feel welcome as a family.”
