1. How long have you been in the industry?
I have been in the trades for almost 15 years. My husband and I own a heating, air conditioning and plumbing company, and while we officially launched our plumbing division in August 2025, my work in the trades has always extended beyond one department or title.
Over the years, I’ve been deeply involved in operations, leadership development, customer experience, process creation, and culture building. I’ve learned this industry from the inside out...from answering phones and dispatching calls to building systems, coaching managers and shaping long-term strategy. The plumbing side of our business is still young, and we are learning every single day, but the foundation we’ve built is rooted in discipline, humility, and a commitment to professionalism.
We have come a long way... and we still have a long way to go... and that journey is something I’m incredibly proud of.
2. What is the most rewarding aspect of your career in PHCP-PVF?
Without question, the most rewarding part of my career is watching people grow.
The trades have the power to completely change someone’s trajectory. I’ve seen technicians come in unsure of themselves and grow into confident professionals. I’ve watched young apprentices discover they are capable of more than they believed. I’ve seen families supported, stability created, and leadership developed because this industry gives people real opportunity.
For me, the reward isn’t just revenue growth or expansion; it’s building a company that operates with integrity, accountability and professionalism. It’s creating structure and systems that allow skilled tradespeople to do what they do best with pride. It’s knowing that when we enter someone’s home, we are not just fixing a system; we are protecting health, safety, comfort and trust.
The PHCP-PVF industry is essential. It requires intelligence, emotional awareness, technical expertise and operational discipline. Being part of elevating that standard, especially as we grow our plumbing division is deeply meaningful to me.
3. What do you wish more people understood or knew about the plumbing industry?
I wish more people understood that the plumbing industry is a highly skilled, regulated and essential profession that safeguards public health and supports the foundation of our communities. Behind every service call is a coordinated system of trained professionals, compliance standards, safety protocols and operational discipline working together to protect homes and businesses.
Plumbers play a critical role within that system; safeguarding water quality, preventing contamination, solving complex mechanical challenges, and responding during some of the most stressful moments in a homeowner’s life. That level of responsibility requires training, critical thinking, professionalism and character. At the same time, the industry as a whole demands strong leadership, sound business practices, ongoing education, regulatory awareness and an unwavering commitment to ethical service.
As leaders in this profession, we have an opportunity to continue elevating how our industry is represented and understood. Plumbing is essential to public health. It is essential to infrastructure. It is essential to daily life. It is skilled. It is disciplined. It is professional. And it deserves to be continually advanced and respected as such.
