I'm an active competitor both in Judo and BJJ (gi and no-gi). I feel that competing is an important (but not mandatory) part of everyone's journey and I make an effort to compete when my teammates/students compete. It is through active competition that I try and stay current with the various rule sets and techniques as well as develop appropriate approaches and strategies as a coach.

I’ve been very fortunate to have had a very rich and fulfilling “Jiu-Jitsu journey” thus far, with so many different sources of influence and inspiration and rewarding experiences along the way. I’ve been teaching BJJ since 2006, when I was a white belt. I’ve worked professionally as a teacher and counselor for most of my career, and I believe that this has significantly both shaped and complemented my path and place in the greater BJJ community. I have a strong interest in working with strict beginners and am always trying to improve my “teaching game,” just as much as, if not more than, my “Jiu-Jitsu game.”

While you can probably find more detailed information and videos, etc on me by just plugging my name into a search engine, here’s a link to a short documentary on BJJ in Moldova I made way back in the day {watch it here} and here’s probably the nicest thing anybody’s ever written about me {read it here}.

Josh Macri is a BJJ brown belt who comes to us from Chapel Hill, NC. He has been training since 2006.  His style focuses on fundamentals and careful attention to detail. In addition to Jiu Jitsu he is also a boxing and kickboxing coach with experience dating back to 2012. His other passion is working as a strength and conditioning specialist with 15+ years as a personal trainer and group fitness instructor. Josh offers one on one and group lessons in all of his areas of expertise and generally gets things started with a complimentary consultation. In the consultation he will take an hour to find out what your goals are, where your current skills are, and see if there’s a way he can help you bridge the gap.

Nate Galtieri

Kids' BJJ Assistant Coach


It is said that everyone has a different BJJ journey, I am no exception.  I feel like it started in 1993, my first year wrestling at Rugby middle school, and then continued at West Henderson High School. It was there that I really learned about the importance of the team dynamic and the strong friendships it creates, similar to what I found later in the military. That being said, wrestling also gave me the courage, confidence and sense of self-accountability that comes from competition as an individual alone on the mat.


Though I have worn a lot of different hats professionally throughout the years I have always wanted to return to the mat to compete and coach young people to do the same.  Open Source has given me the perfect opportunity to do that. I feel that the life and character lessons that I learned from coaches in general - but especially wrestling coaches - have profoundly shaped me and made me a better person. I think I have always wanted to be a part of shaping both a skill-set and the character of as many young people as I can, including (especially) my own. My two teenage daughters also train at Open Source and actively compete multiple times a year.


I really feel like we are building something here at Open Source that will continue to benefit everyone involved in our BJJ family as well as the community in which live. I can’t wait to see what the future holds.

Jeff Tipton

Judo Instructor


Jeff Tipton is a Nidan (2nd degree Judo black belt) who started studying judo in 1993 with the Asheville Judo Club under Sensei Wayne Jersey and later on studying traditional JuJitsu under Sensei Carl Wilcox and Sensei Jeff Rhodes of Center for Martial Arts in Asheville. He was introduce to judo by his father, David Tipton, who had started judo a year earlier and invited him to express his natural talents of subterfuge and being in exactly the wrong place at the right time. Studying judo with his dad for so many years is one of his great honors, defining their relationship and bringing them closer than either thought possible.

Having previously studied at The Southern Academy of Ballet in Tallahassee, Jeff was looking for the next form of physical expression. Judo fit the bill perfectly. The two principles at judo's core being efficiency of effort and benevolence resonated deeply with Jeff. He realized judo is the physical syntax of these ideas, expressing them more fluently than any spoken language can. Now in middle age, Jeff has discovered the joy of watching students grow both on and off the mat.

Craig Econopouly

Judo Instructor

I began studying Judo in 1965 when I was 10 years old. I studied under Joe Turchiano (8th Dan) and now deceased Jimmy Zaubantes (5th Dan) at The Black Belt Academy in Hicksville Long Island. Joe Sensei has direct lineage to Kano by training under his two next in line Otaki & Kotani, Kodokan Professors.

I placed 2nd in the AAU (now junior Olympics) in the Juvenile division and attained my Sankyu at the age of 13 and Nikkyu at the age of 15. Later on in life I studied at Sandia Judo in Albuquerque, NM under Jesse Ballou Sensei (7th Dan) where I earned my Ikkyu and trained with many world Champions in Master division. I competed until the age of 35 in some prestigious tournaments such as The Ladder Tournaments.

I moved to Florida and after not finding any dojos available after several years, I opened Gurizuri Judo & BJJ Dojo around 2010 (still in operation) and taught both children and adults.

I am a plumber by trade and businessman. I also taught in post secondary education for five years, which helped me in teaching others Judo and its studies. I presently hold the rank of Sandan (3rd Dan) in judo and a blue belt in Japanese ju jitsu. Judo has made me so many life-long friends and taught me so much about life and dealing with others. It was very helpful in making my businesses successful and lucrative. I am very glad I was able to find such a great dojo so close to me here in Asheville and enjoy working with the other students and staff.
