One Spirit Martial Arts (OSMA) located in Herndon, VA is home to one of the better MMA schools in the Northern Virginia, Washington, DC Metro area. The school itself has been through many different iterations from a strictly TMA school (Shotokan, Taekwondo, Hapkido, etc.) to a full gamut MMA gym offering pretty much everything you would need to compete under one roof.
OSMA is of moderate size, located in a mixed development office/warehouse park. There is a large mat area with plenty of room to comfortably hold up to 30 students at any one time. Being a mixed martial arts facility, OSMA offers all your basic combat training in striking (Muay Thai), grappling/submission (BJJ/Judo), Krav Maga, JKD, and Kali. Classes are also offered in MMA training for aspiring professional fighters. The only real complaints I have is that the mats are usually dirty since the Krav Maga classes wear their shoes on the mat. It’s a pain in the ass having all these nasty smears on my gi after a workout. Also the building itself is starting to burst at the seams it seems. When the classes are packed, it's packed. You don't have much room to work with, especially in BJJ. The Krav classes are a pretty much chaotic as it is. There are plans to move to a bigger facility within the next few months. It's still a pain in the ass to grapple when you have two feet of dedicated space to yourself.
OSMA proudly boasts (and I emphisize that) the acclaim of being the new official headquarters of the Pedro Sauer Jiu-Jitsu Association. As of September 2006 Master Pedro Sauer, 7th Degree Red-Black Belt under Helio/Rickson Gracie, picked up camp in Salt Lake City and moved operations to OSMA. Master Sauer personally instructs the Monday through Thursday classes and travels to host seminars throughout the association on the weekends. The Brazilian Jiu-Jitsu classes are top notch, Gracie Academy level, packed with step-by-step, technical run downs on every technique. This should be expected considering Master Sauer's highly acclaimed instruction (voted Most Sought After BJJ Instructor in a ADCC poll in 2005). Classes run an hour and half with 15 minutes of warm ups, 45 minutes of instruction, and 30 minutes of drilling and rolling. Thursdays we have the pleasure of hosting Maurice Allen, 8th Dan Judo master and head instructor of Sport Judo provide an hour long session on Judo takedowns to suppliment BJJ. The school also offers a Junior Jiu-Jitsu program 3X a week.
Other classes are an hour to two hours (muay Thai) long each with a dedicated instructor. There are no Jacks-of-all-trades that teach every class here. Many of the students do, however, cross train, which is encouraged for those wanting to join the local circuit. OSMA no longer offers Taekwondo or Hapkido but still has Judo, Aikido, and Kali. You will find that the student population is very friendly (leave your ego at the door) and helpful.
Contracts are basic no frills, what you see is what you get. No shady tactics here. They offer single classes all the way up to two year terms. Signing up for the two year gives you $99 a month of unlimited training in any one of the styles offered (add $24 to the price if it is BJJ—only because the classes are an extra 30 minutes longer). There are also packages which allow you to take two or more styles if you like at a discounted rate. The staff is friendly and knowledgeable (All the staff are students of one style or another) and they are more than happy to answer all your questions upfront.
