“I reached out to Mike about a training opportunity my church, Westfield Presbyterian, was considering for it's congregation. I had seen that he was local to the area and appreciated his BJJ lineage. After connecting with him by phone, I knew he was the right guy! I then put him in touch with the church's coordinator and they got everything settled. While I wasn't on site for his training, I got great feedback from the participants in the training. Mike was knowledgeable, professional, and above all, relatable. That day, he was training all ages and did so accordingly to capabilities. We were all grateful of that. We highly recommend Wrecking Crew BJJ and Mike Demko for a similar group setting training!”
