About the Instructors:

Mark Turner
BJJ Black Belt

Mark Turner is the first and only non-Brazilian Black Belt of 5 time World Champion and current UFC welterweight star Demian Maia. Mark is an active competitor and has competed and/or placed in jiu jitsu championships held in Brazil, the United States and Europe.

“I love to compete and I have a lot of fun at the championships win or lose, but my true passion is passing on the knowledge and teachings of jiu jitsu to my students.  Technique is everything in jiu jitsu and I feel it is very important that the students not only practice and drill what they are learning, but it is of great importance that they really understand the technique in regards to how it works and why it works” – Mark Turner

Mark has fostered an environment conducive for fun and competitive training. Students are always willing to help one another improve. Iron sharpens iron so all can improve. If you are looking for great training, fun, competition, self improvement, and confidence Mark Turner BJJ is the place for you. We hope to see you on the mat!

John Wolnik
BJJ Black Belt

John Wolnik

John has been training under Mark for over ten years, and recently received his black belt. John is a terrific instructor who like Mark is very detailed in his instruction. At Mark Turner BJJ we teach you techniques that overcome strength and athletic differences. John started BJJ at the ripe age of 38, and is now a world class black belt. John is unique as a big guy because he rolls like a little guy, i.e. he uses technique over strength and will invert at anytime. John has competed in and won many tournaments. Most recently John won Gold in the black belt super-heavyweight division at the 2017 IBJJ Chicago International Open and is currently training for Masters Worlds. In addition to being a passionate BJJ player John specializes in sports strength and conditioning, weight/fat loss, supplementation and nutrition, and is experienced in using Russian Kettle Bells. He is a member of the A.C.E (American Council of Exercise) and the National Academy of Sports Medicine (NASM) as a Certified Personal Trainer(CPT). “I am passionate about Brazilian Jiu Jitsu and remember what it was like when I started. I use that knowledge with what I currently know to teach others. If you join our team you will see me on the mat having fun and sharing my knowledge.”

John Brooks
BJJ Brown Belt


John Brooks has been training with Mark since 2013. John is an instructor that breaks things down scientifically so you learn the fundamentals and principles of the movement, rather than individuals moves. John is an active competitor and multiple time IBJJF tournament Gold medalist. John is also a nutrition and fitness expert, as he holds a Master of Science degree in Nutrition and Wellness, and is a Certified Sports Nutritionist (CISSN) through the International Society of Sports Nutrition. John prides himself on maximizing the physical benefits of BJJ as a mixed sport athlete.

“I love what Brazilian Jiu Jitsu does for me in changing the way I think as a problem solver. I enjoy the challenge and love the commorraderie among my teammates and competitors alike. You read that correctly, I feel admiration for those I get to compete against as I respect and appreciate them being there for me to test myself. I also love using BJJ as a part of my fitness to maintain a healthy physique, my job more or less requires that I look the part and BJJ makes it fun. I love seeing new people discover the great, kingly (hat tip John Danaher) art that is BJJ.”
