We at PIE have been privileged to work with—and learn from—Paul over the years.

His knowledge, mentorship, and sense of humor have made him not only a valued teammate, but a true friend to many and a legend in the industry.

The entire PIE family wishes Paul a very happy, well-deserved retirement!

Congratulations Paul!!
