Tom's Retirement Letter:

Bob Stahl asked me to say a few words now that I’ve retired. Yes, I’ve hung up my briefcase and called it a day – and a career. About the time when I neared 80, it dawned on my wife Kathryn and me that we didn’t need the money and there were some places throughout the world that we really wanted to see. It’s been a great run: writing over a dozen books, making videos, teaching all around the world, giving advice to large and small companies about implementing Sales & Operations Planning. Sure, it was a fair amount of work but it was even more fun. I loved it and I offer a heartfelt thanks a million to all of you with whom I came in contact over the years.

The T. F. Wallace book business has been turned over to my long-term colleague,  co-author, and friend  Bob Stahl, who will continue to be active in the field. If you want coaching help on implementing S&OP, or have a question about that, or have a question about the books, you can reach Bob through this website. He’s the best S&OP coach/consultant in the world and that was true even before I retired. He won’t steer you wrong.

Cheers,
Tom Wallace
