Practical, pragmatic, and to the point is how Joe Masterson describes himself.

In his spare time, Joe enjoys reading, cycling and travel.

“I always wanted to be a litigator,” he recalls. “I guess at heart I'm a bit of a fighter. When I started my legal education, I wanted to be a criminal lawyer. It wasn't until 1990 when I was articling at Lerners that I changed course — no doubt influenced by the example set by the senior litigators at the firm.”
