My Area of Specialization

My Career High

My proudest moment was the evening of the day I defended my doctoral thesis at Columbia University. After six years of ups and downs, I sat on the steps of Low Library just beneath the Alma Mater statue and lit up a cigar. My wish at the time was that my father -- a proud traveling salesman -- could have been there with me. I still miss him every day but I know on that day he would have been so proud of what we had accomplished. By the way, that thesis became a bestselling book, The Synergy Trap.

It is well known that mergers come in waves – but the only way we get waves is when companies all of a sudden start doing things they haven't done before. Reactive behavior in M&A will rarely lead to building shareholder value, most likely just the opposite as we also know well.
