"Very happy I decided to train at this school! Marcelo is a wealth of knowledge. He has taken my jujitsu to anther level. He is very generous with his knowledge. He takes time to show everyone how to make the techniques work for there body types. I feel that I am always having aww haa moments. He also has a great sense of humor and the atmosphere is light and fun. Aside from Marcelo himself the rest of the staff is very knowledgeable fun and welcoming. I am happy to be a part of this team and to have made so many great friends. I can't say enough good things about this place. It has been great having the brand new facility as well. The workout is second to none. I have had my 14 year old now 16 year old boy training here for the last 2 years and the experience has been priceless. The change it has manifested in his life is truly remarkable, confidence, strength, discipline, hardworking, and social skills to boot. Marcelo and the rest of the team have taken him under there wing. These people are the salt of the earth. If you live in the area and are interested in martial arts you should definitely check this place out."
"I've trained under Professor Marcelo Alonso since I was 16 years old. Made it from white belt to black belt with him! I own my own academy in Monroe, Wa My life would not be what it is without Marcelo Alonso Brazilian Jiu Jitsu 5/5"
"He is the Encyclopedia of Jiu-Jitsu and THE BEST in the Northwest to learn from! Marcelo had such a fun personality, anyone will enjoy the environment!"
"My two boys (8 and 11) are in the kids program, and I train there as well. Marcelo's has been a fantastic place for our family. My kids absolutely love MABJJ and it's had a huge impact on their confidence, discipline, and toughness. The coaching for the kids program is extremely strong, with tons of individual attention and a culture that encourages the best aspects of martial arts. It's been amazing watching my sons progress from knowing nothing of jiujitsu to watching them roll with solid technique in just over a year. I can't praise MABJJ (and 'Coach Pete' who runs the kids program) enough."
