I liked the class. It was very thorough and I learned the essentials for carrying and I feel much more prepared to carry than I did before this class. Don was my instructor.

I highly recommend Don Haworth and his Stop the Bleed class. Don is an excellent instructor—knowledgeable, professional, thorough, and very effective at explaining the material in a way that is easy to understand and remember. I was extremely pleased with the quality of the instruction and the amount of practical knowledge I gained by completing the class. Don clearly knows his subject inside and out, and his experience and confidence as an instructor really show. He takes the time to make sure everyone understands the techniques and feels comfortable applying what they’ve learned. This was an outstanding class and absolutely worthwhile. If you have the opportunity to take a Stop the Bleed class with Don Haworth, I highly recommend it. Five stars all the way!
