Guido's friendship, patience and willingness to help others has made possible my advancement in Gracie Jiu Jitsu. His knowledge and experience were key to help me improve and better understand this art. Alberto Robayo Gracie Jiu-Jitsu Brown Belt Main Line Gracie Jiu Jitsu Greater Philadelphia Area, US
 Always learning from the best, Guido has been training Gracie jiu-jitsu for over a decade with names like: Rorion Gracie, Rener Gracie, Ryron Gracie, Caique Elias and Royce Gracie; Jenniges is one of the few non Gracie black belts that the Gracie Jiu-jitsu Academy in Torrance California has ever produced. He is always at the academy training and helping the lower belts. In the personal level he is a great guy, he has helped me a lot with m mount defense – Guido’s top game is brutal,  his cross choke from the mount is legendary and he just brings it to you with lots of pressure… like a German fine tuned machine. When he mentioned to me that he was going to teach overseas I thought it was a great idea! People from Europe and Asia are going to be able to learn right from the source, since Guido has been learning from the creators of the art. I am glad to say that Guido is my friend - A great black belt and instructor. Ricardo Bayona Gracie Jiu-jitsu Academy instructor
"Guido Jenniges is very competent when it comes to teaching Gracie Jiu Jitsu. He is very generous with his time and knowledge. He is also a very patient instructor. I have benefited greatly from having trained with him. Every time I "roll" with him, I pick something up that I hadn't learned before."

I 've had the pleasure training and rolling with Guido. He is a great instructor and breaks things down to science. He has the ability to break down a very complex move into different steps allowing easy repetitions and faster learning curve. He takes pride, lives, and breaths BJJ. Great guy as well. Thanks Master Guido!!! Walter C Torrance, CA
I have been practicing GJJ for 5 years and Guido has always been around as an instructor. I always look to roll with Guido since I know I will be learning something new. What amazes me most is that he always stays calm, no matter how much pressure I am putting on him. He always keeps  his composure and is very relaxed. As a law enforcement officer Guido's behavior has taught me much. I know that I have to stay calm in a real life confrontation and I know that I can get the job done. Guido's teaching has made me a more confident and efficient Jiu Jitsu practitioner and law enforcement officer.
