Manager Tools has been the single best resource for my career and personal development. I had received 360 feedback that I was not a good supervisor to many of my directs. Basically I was a terrible listener and not my true self at work. Studying the Trinity and DiSC has been life changing for me. The transformation I made over the year following this feedback led to a new level of respect from my manager. It has helped me to become a better husband, father and friend as well.
