With over 40 years of martial arts training and more than 15 years as the Head Coach and Owner of Five Rings Jiu Jitsu, I am driven by a clear purpose: to cultivate a community where individuals come together to learn, grow, and support one another through the art of jiu jitsu. My journey began in 1984, and my transition to Brazilian Jiu Jitsu in 1993 opened the door to countless friendships and connections within this incredible tribe.
Five Rings Jiu Jitsu is not just an academy; it’s a vibrant community focused on personal development and mutual support. I aim to create a positive and challenging environment in every class, helping students develop their skills while fostering camaraderie. I feel fortunate to share my passion for Jiu-Jitsu and to witness the amazing transformations that happen on and off the mats.
As a proud member of the Five Rings family, I look forward to empowering our students and contributing to a beautiful culture of resilience, strength, and support. Jiu jitsu may be challenging, but with a greenhouse of support, our journeys become so much richer. Let’s train together!

Watching students grow and thrive fills me with gratitude and excitement!

I started my jiu jitsu journey in 2009, initially as a college elective, and I was hooked from the very first class! My passion for the sport has only grown since then, and these days, I’m particularly focused on pressure passing, wrestling, and the K guard.
As a coach, I find immense joy in helping students make new connections in their game and witnessing their growth, especially during tournament preparation. There’s nothing quite like seeing someone overcome challenges and thrive on the mats. I’m excited to share this journey with you all and help you reach your personal best in Jiu-Jitsu!

I’ve been training in Brazilian Jiu Jitsu since 2004, and my journey has taken me to various places, enriching my experience with diverse styles and techniques. I view jiu jitsu as a form of embodied meditation, a way to focus on the present moment. I love breaking down techniques to help learners understand the “why” behind each movement. Outside of training, I enjoy parenting, playing guitar, and exploring AI in healthcare. Let’s grow together in the Five Rings community!

Coach Ryan Kivett

I started my martial arts journey in Taekwondo before discovering Jiu-Jitsu in 2015. I quickly fell in love with Jiu-Jitsu and began coaching kids in 2019. Now, I’m thrilled to coach the adult fundamentals class as I continue my journey as a brown belt. I’m passionate about sharing this art and can’t wait to see you in class!

Coach Matt Krier

Jiu jitsu has brought me immense joy through the challenges of learning new skills and building friendships. As a coach, I love seeing students put their skills into practice and thrive. I encourage everyone to give coaching a try—it deepens your understanding of techniques! Outside of Jiu-Jitsu, I enjoy running, spending time with dogs, football, and floating the river. Let’s train and grow together!

Coach Benji Hildebrand

I’m a Purple Belt under Professor Tom and Professor Dan. I’ve been at Five Rings for about 3 years during which time I’ve won 2 Masters World titles. I do Jiu-Jitsu because it demands that I keep working toward the best version of myself. My Jiu-Jitsu game relies heavily on wrestling, fitness / conditioning and preparation. As a professional trainer/strength coach for the last 24 years, I’ve worked with everyone from 3 yr olds to professional athletes. So if you train at Five Rings, regardless of age or skill, I got you! Also, I’m the point person for all adult marketing and sales at Five Rings.

Coach Mike Lennon

I joined the Jiu-Jitsu community about 9-10 years ago, inspired by watching my older son in kids’ classes. I love how Jiu-Jitsu presents an ever-evolving puzzle that keeps me engaged and coming back for more. Through coaching, I hope to share the excitement and encouragement that Jiu-Jitsu brings. As a stay-at-home dad for 17 years, my family is my passion outside the mats. Let’s train and explore this journey together!

Coach Riley Little

Hi there! I’ve been practicing Jiu-Jitsu since 2011, and I love so many aspects of it. I coach the youth classes, and there’s nothing more rewarding than witnessing that moment when a student masters a technique. Outside of Jiu-Jitsu, I enjoy importing music from France, playing video games, and writing quirky novels. Let’s enjoy this journey together!

Coach Kyle Williams

I started my Jiu-Jitsu journey at the end of 2020, and the friendship and accountability at Five Rings have kept me coming back. As an assistant coach, I’m excited to learn while helping others grow. Outside of training, you might find me on my motorcycle or camping in the Tillamook State Forest. Let’s support each other in our journeys!
