Keith Farrell teaches HEMA professionally, often at international events (why not hire me to teach at your event?), and has an interest in coaching instructors to become better teachers.
I have authored Scottish Broadsword and British Singlestick and the award-winning AHA German Longsword Study Guide, and maintain a blog at www.keithfarrell.net where I post regularly.
