Sandler has helped me better communicate in my professional and professional life.
The process of leveling the playing field with the people you are meeting with. Sandler allows the initial appointment me an interview for both parties. I also feel the process as a whole is very important. It gives you steps, bonding and report, up front contract, pain, budget decision, fulfillment and post sell. All very important tools.
I can't think of anything specifically I dislike.
You need to be committed to developing your sales team and 100% committed to the system. If you are considering Sandler Sales Trainig, it's obvious you have reservations about your current process and the development of sales team. This system requires practice and is very interactive. If you can't make that committment, find something else.
