Testimonials from Existing Students...

The best way to find out what we are all about is from those who train with Professor Dan.

  • Juliana has been a great coach to our 3 kids, for the past 3 years. She has always shown care and dedication in teaching our kids, with an unlimited amount of patience. A quote from our 12 year old: “she is nice, patient, and real good with kids.

    Felix Reyes

  • Dan is super patient with your questions, and he treated everyone with respect - no matter what your level was. He’s also super nice and has great technique, which is what I look for in my instructors! I would no doubt in my mind recommend Dan to anyone coming to him for Jiujitsu, whether it’s your first day or a higher belt looking for some good training!”

    Liz Hwang

  • I have had the pleasure of being associated with Daniel for over 10 years. Over this time period I have witnessed his evolution from dedicated student to highly competent and capable instructor. I have come to rely on his thinking, knowledge and intuition as he tends to tackle difficult concepts and techniques in approachable ways. He is always willing to listen and is a great coach, leader and friend. I would highly recommend training with Professor Daniel - but do not take my word for it, check it out yourself!

    Jae Chang

  • Daniel D'Elia is one of the best bjj teachers I have ever trained with. He has a strong understanding of the techniques he's teaching and can articulate it well. I'm a police officer and my need for bjj comes from a self defense application. After explaining a move to me, he can immediately adapt the information to another student who is looking to compete in a sport setting. Dan will take anyone, with the commitment, from white to black belt. He and his wife Juliana have been great training partners and friends."

    Dino Barberis

  • Dan D'Elia, known by many as “Sleeves”, has been my friend, training partner and teacher through our training at Renzo Gracie Northern Valley under the brilliant Prof. Carl Massaro. Since my jiujitsu beginnings, Sleeves has played a great role in the development of my game through his ability to provide instruction in a cerebral and effective manner – he is, without a doubt, one of the most talented jiujitsu practitioners that I know and whose fundamentally solid practice of the art I strive to emulate. Even after several years, I still utilize the techniques and concepts that I learned from him during my most novice years and continue to expand on these to improve my jiujitsu game. Whether you are a beginner white belt or an experienced grappler, I am confident that training with Dan can provide tremendous value towards improving your understanding of the art of jiujitsu.

    John Marasigan

  • I have known Professor Dan since I started BJJ. He’s helped me out a lot to throughout these years with my progression in BJJ. He is one of the best BJJ instructor I’ve had. He is very engaging and always takes the time to answer your questions after class. His knowledge and passion for this martial art shows when he teaches classes, he’s got an excellent technique. His knowledge of the art is constantly evolving. Most of all Dan is a good guy, he is always there willing to help anyone out during class.
