    I have been training with Ryan for about a year now at Kaminari. Ryan is an extremely knowledgable coach, and an excellent teacher. No matter whether you are a competitive mixed martial artist, or just looking to shed a few pounds this is an great gym. We have some of the freindliest students I have ever met. It creates a fun workout environment, and one that challenges you to improve. Our competitive team includes both amatuer and proffesional level fighters. If you’re looking for a great way to get in shape this is one of the most fun ways to accomplish that goal. Ryan specializes in grappling, and is one of the most impressive practitioners I have ever had the pleasure of rolling with. Come in and check it out sometime. You will be glad that you did.
