Sharon is, bar none, the best in the industry. She's head and shoulders above any other moderator. In Sharpen the Focus she teaches about real-world issues with role-play practice for the types of situations that moderators are likely to encounter. That experience is invaluable. Her teaching material is the best I've ever seen, whether it's a workbook or text. Most materials currently on the market are all theory or if they're practical, they're uninspired and miss the psychological objectives. You get information in Sharpen the Focus that you simply cannot get elsewhere.
