As captain of my college fencing team, I learned to appreciate the importance of developing trust with my teammates, opponents and the referees, and other lessons that benefited my development as a trial lawyer, such as knowing when to attack and when to remain defensive minded. The tactics of good fencing are actually quite similar to those of a good litigator.

After reporting his findings to the company, the company CEO accused the accountant of defamation, tortious interference, participating in a civil conspiracy, and intentional infliction of emotional distress based on alleged conduct that occurred during the course of the investigation.
