What’s your proudest professional achievement?

The closing of each M&A deal that I have ever been intimately involved with.

If you weren’t an accountant/consultant, what would you be?

I would be in M&A Advisory. Or I would start a start-up that helps other start-ups start up. (Plagiarized from a New Yorker Magazine cartoon).
