YOUR COACHES

SBG Idaho offers world class martial arts instruction across numerous disciplines with over 80 years combined experience! All of our coaches have passed the SBG Coaches Course certification in order to bring you the best possible training experience.

His goal was to create a university of fighting, where the truth of what does and does not work could be explored – an academy where ‘best practices’ could develop – where form would follow function. Our coaches strive to follow this dream. We welcome you to come join the SBG Idaho Tribe and experience it for yourself!

JAKE MARTINEZ

[Brazilian Jiu-Jitsu ]

My Jiu-Jitsu journey started at Xtreme Couture in Vancouver, WA in 2007. Walking into that gym was both terrifying and exciting. Out of shape and never having played sports, I wanted to quit 10 minutes into my first class. Feeling that I had made a terrible mistake and was ready to walk off the mat, I was given a promise from my instructor “come in every day for 30 days and you’ll never quit”. It made me angry, so angry, that I showed up to every class just to show him that I didn’t want this and that I wasn’t going to renew my contract. After a few weeks my anger faded, the workouts got easier, and 30 days later I signed a 1-year contract. The next few years would be spent rolling 7 days a week gi and no-gi, wrestling, going from 290lbs to 220lbs, and competing around the northwest with my first coach and BJJ black belt Chris Dealy.

No matter how small or weak you think you are, you can train Jiu-Jitsu with consistency and patience.

Ever since then Ryan has been an avid student and competitor in BJJ, and describes it as one of the most valuable aspects of his life.

SCOTT SMALLEY

[Muay Thai]

I became interested in martial arts at a young age and began training at a Tae Kwon Do Academy when I was five, and again at the age of 10. At the time, the lack of full-contact training kept it from truly capturing my attention. Many years later, I saw Anderson Silva knock out Rich Franklin with a gnarly head kick and it piqued my interest again. In 2010 I began training much more seriously with a group of like-minded friends. I became obsessed with learning all facets of striking and grappling and discovering the best way to connect them together. This naturally led me to SBG Idaho, where the extensiveness of my training deepened even further, and my skills and understanding of self-defense and the sport of MMA grew rapidly. I now hold the rank of blue belt in BJJ from Scott Thometz and assist in teaching the Muay Thai classes. Teaching has been a very rewarding experience for me, as it increases my own knowledge and allows me to help others develop both mentally and physically, gain true confidence in their ability to defend themselves, and live a healthy lifestyle.

JESSICA SEGALI

[Fitness / Strength & Conditioning]

My name is Jessica Segali and I coach Strength & Conditioning at SBG Idaho. Shortly after enrolling my boys in the Growing Gorillas program in 2016, I began training my own fitness journey, training with Coach Holly. In 2018, I began teaching at SBG Idaho myself after receiving my Suples Level 1 Certification and passing the SBG Level 1 Coaches Course. Over time, SBG Idaho has become my comfort zone, where I am surrounded by people who genuinely want to see each other succeed. From children to doctors, to the checker at your local grocery store, we step in the gym label-free and there is a community being built.  That is why I love coaching at SBG Idaho.  I love being a part of something that positively influences others. My fitness journey outside of the gym includes recreational sports like volleyball and hiking outdoors!

SBG Coach picture - Robbie Newman

ROBBIE NEWMAN

[Muay Thai]

In learning how to help others, Robbie learned the hard way that it is also important to help one’s self. During graduate coursework in counseling, Robbie took up Muay Thai and has since made it an important point to incorporate its discipline and philosophies into a life practice. In doing so, Robbie has found value in Muay Thai’s teaching of a new level of mindfulness of one’s own body. Robbie’s belief is that a person can incorporate this mindfulness into a new understanding of the person’s sense of self and the world around them. Robbie also tries, (and may or may not be successful) to incorporate humor and admittedly nerdy pop culture references in his explanations of techniques. In addition to coaching and training at SBG Idaho, Robbie also serves as a Licensed Clinical Professional Counselor in multiple locations throughout the Treasure Valley. Robbie often enjoys water and snow sports with other members of the SBG Idaho family. Robbie serves as an advocate for anyone looking for a supportive and safe space to learn and grow with others.  The SBG Idaho Tribe has been an incredibly positive force for Robbie and he strives to pay their support forward.

Stephen Stirewalt

Stephen Stirewalt

[Boxing]

Stephen began his martial arts journey at the young age of 5, when his parents enrolled him at the Karate Tech school in Ramstein, Germany, as a means of general self defense. Being part of a military family, he never had the chance to stick with any one particular school for long, but continued to train and compete in more traditional forms of martial arts (i.e. Karate, Kajukenbo, etc.) for a good chunk of his young life all over the world! In June 2012, upon graduating high school in Mountain Home, Idaho, and having followed the UFC and the sport of MMA a number of years, decided it was something he wanted to try. After researching gyms in the nearby city of Boise, he decided to begin his MMA journey at Combat Fitness (now known as SBG Idaho)! 5 months later, in November 2012, Stephen had his first Kickboxing bout and won by split decision. He has been hooked ever since! Stephen currently holds the rank of Brown Belt in Jiu-Jitsu, fights professionally in MMA (Pro debut May 2018), and teaches the foundations boxing class in the evenings.

Rebecca Rogers

[Muay Thai / Boxing]

Rebecca Rogers has been training martial arts since 2015. She first started with a cardio kickboxing class that really began to pique her interest in Muay Thai. She found the cardio bag class to be a fun way to work out, however, she soon desired more technical training. This prompted her to reach out to SBG Idaho, where she began training Muay Thai and fell in love with the art. She then began boxing, and is now dedicating a substantial amount of her time to training Brazilian Jiu Jitsu. Rebecca has also recently transitioned into coaching, where she assists Foundations Muay Thai and boxing classes, and has been thoroughly enjoying it. She loves sharing her knowledge with others who bravely choose to step out of their comfort zone and try something new. When Rebecca's not in the gym training, you'll find her in a coffee shop drinking an Americano or at home in her small makeshift studio designing jewelry.

Jo Guinness

[Muay Thai / Boxing]

Born and raised in Columbia, South Carolina, Jo Guinness is no stranger to fighting. A veteran of the underground punk scene and a retired officer in a motorcycle club, violence became routine. After witnessing the murder of his best friend, the stress, frustration, and anger would eventually become crippling. Moving to St Louis shortly after, a change became inevitable and necessary. Jo decided that he needed an outlet and found himself signing up at the local boxing club. While boxing, Jo would also begin training Muay Thai and Brazilian Jiu Jitsu; earning his blue belt from Royler Gracie. After years in Missouri, Jo would relocate to Virginia where he would continue his Muay Thai and Jiu Jitsu training. While training out of The House of Muay Thai in Norfolk, VA and competing in over 20 unsanctioned amateur fights, Jo was booked to compete on a national level in 2020, but COVID-19 cancelled the event. Jo has assisted both as a coach and a training partner in training camps for UFC, Bellator, LFA, IKF, WKA, and Invicta competitors and champions. Jo now finds himself in the Gem State with his wife, Marina and son, Oliver, and is thrilled to show the world that Straight Blast Gym has more than just incredible jiu jitsu.
