Jack did a fabulous job for us. I was the CEO of an ESOP company with a CEO succession dilemma. I was having trouble moving forward with what needed to happen due to some complicated family dynamics. Jack recommended a 2-day retreat for 30 leaders in our company. Jack worked incredibly hard from 8am to 7pm both days, keeping everyone energized and at the end of the second day we had achieved complete agreement among all parties that of the top 10 company issues, identifying my successor was by far the most critical.
Jack lit a fire under me to make some tough decisions and this resulted in a series of events that resulted in an increase of the value of our ESOP stock by 1000%. The reason for 4 instead of 5 is that Jack can be very direct and tends to ruffle some feathers with some of the more sensitive types. But as far as results are concerned, he earned 5 stars.
