Founder, Grappling Strength & Performance

Hi! I’m Matt Guffey –

For the past 18+ years, I’ve been devoted to helping others through personal strength training. I started coaching AAA hockey for the San Jose Sharks in 2015. And in 2020, I opened my own strength training gym, Grappling Strength & Performance, in San Jose, California.

My team and I at GSP are dedicated to changing people’s lives through individualized strength and mobility programs. Our gym has quadrupled in size since we first opened, and I was voted Business Owner of the Year by Results Fitness University in 2022!

Now for the alphabet soup: I’m a Certified Strength and Conditioning Specialist (NSCA), Certified Functional Range Mobility Specialist (FRC), Certified Functional Strength Coach (CFSC), and earned my brown belt under 12x World Champion Professor Caio Terra.

I specialize in working with grapplers of all sizes, ages, and skill levels.

If that’s what you want, book your strategy session at Grappling Strength & Performance today.

See you in the gym!

Matt Guffey

Meet the Team

  • Josh Lundy

    Josh has a Kinesiology degree from San Jose State University, is a Certified Strength & Conditioning Specialist (NSCA), and has been a sports performance coach for 14 years.

    He is a blue belt in jiu jitsu and played hockey for the Santa Clara Blackhawks as well as SJSU. The energy and experience he brings to the training floor are unparalleled—Josh’s ability to connect with athletes and meet them where they’re at are invaluable!

  • Brendan Tydingco

    Brendan is a Certified Functional Strength Coach (CFSC), Certified Personal Trainer (NASM) and fourth year Public Health major at San Jose State University. He grew up playing hockey for the Santa Clara Blackhawks and San Jose Junior Sharks.

    Brendan is hands down the best at cultivating a vibe in the gym (ask him about all things music) and is constantly on the lookout for the best spots to eat in the Bay Area. His ability to learn quickly and create deep bonds with the athletes he coaches make him a valuable asset to the GSP team!

  • Bishop Nazareta

    Bishop is a San Jose State alumni with a bachelor’s degree in Kinesiology, a Master’s degree in teaching, and is also a certified personal trainer (NASM). His coaching experience includes teaching physical education at high school and middle school levels as well as leading youth BJJ at Daruma Dojo for over 2 years.

    Bishop has accumulated many years of grappling experience since age 12. He has competitive experience in wrestling and Brazilian Jiu Jitsu, while also picking up judo recreationally (holding a purple and green belt, respectively). Talk to him about his favorite grappling techniques, as well as what’s going on in the sports world (specifically basketball, football, and the UFC)!
