How long have you been in the PHCP-PVF industry?
As a fourth-generation plumber, I was born into the construction industry. Professionally, I have been engaged in the plumbing and mechanical industry since 2005, nearing 20 years of working hand and glove with the trades.

What drew you into the industry?
As a kid, my father would point out all the projects he was involved with nearly every time we left the house. I think it was then that I realized I could be part of something bigger and participate in building the world around us.

What is the most rewarding aspect of working in the industry?
Simply, helping people. Throughout my career, I’ve been fortunate enough to help so many of my union brothers and sisters by contracting major projects in my region, engaging in emergency health care response efforts and now by getting to be a voice of advocacy for safe systems and trade education.

What is one thing you wish more people knew/understood about the PHCP-PVF industry?
It’s still the best-kept secret just how many avenues are available to tradespeople once they have mastered their craft. I am actively working to self-publish a co-authored book called “Throw a wrench in your plans – an Atlas to the Industry” that will include “coveralls to CEO” stories highlighting these unique opportunities and roles. The piece is meant to spotlight all the relative industries one could explore, after learning the skills of the trade and I think these stories need to be shared widely.

What has been the proudest moment in your career so far?
Aside from the completion of numerous iconic NYC buildings and institutional construction projects, I would say the proudest moment of my career thus far was accepting my new role at IAPMO. Working with my current team and getting to be involved in so many important industry conversations has been incredible and has given me a sense of immense pride and purpose.

What is one thing most people don’t know about you?
I’ve been doing some deep dives into my genealogy over the last few years because I’m a bit of a history nerd. I found out recently, after reading a book called “The Real McCoy,” written by Jack Hoye, that my great, great, great, great (maybe one more great) Grandfather John Mullin (Born in Wales on May 4, 1874) played a major role in the construction and organizing of the “New Croton system” a major upgrade to the “Old Croton Dam” in upstate New York in the late 1800s. The Croton dam provides New York City with its fresh water supply, and at the time, this expansion was sorely needed to meet the demand of the developing city.

So, it’s pretty cool to know that my family has historically played a role in the modernization of waterways and supply systems.
