The instructor was professional, knowledgeable and approachable. I'm new to New State and it's gun laws, Mr. Gridley was able to answer my questions due to his years of experience. He maintained control of the class, kept us engaged with varies examples/scenarios and was able to meet every student at their individual skill level. I feel confident in the safety measures he demonstrated and I will be taking future personal defense course with Mr. Gridley through Rochester Personal Defense.Also, his co-instructor that joined the class on the second day during live-fire exercises was calming and help the students get over their "nerves".
