Great atmosphere. The other students are friendly and happy to work with you from day one. Mix of experienced martial arts practitioners and complete newbies. Everyone is concerned about preventing injuries. I've experienced no problems with egos creating issues.
Mostly male classes, but when females attend they aren't treated differently. You won't have to worry about no one wanting to practice with you, or someone creepy always wanting practice with you. Everyone is respectful of their fellow students regardless of gender. I would feel comfortable with my wife attending classes alone here.
Knowledgeable staff who genuinely want you to succeed. If your willing to show up and work they will teacher you what you need to know to defend yourself. I still have a long way to go, but feel I'm already much more capable of defending myself then I was when I started. Stop reading and give them a call :)
