My story
Building the kind of company I’d want to work for
I grew up helping my dad with projects—building fences, painting houses, laying tile, and doing whatever the job needed. I enjoyed working with my hands and seeing the results of a day’s work.
In 2010, I left college to join a plumbing company. Over the years, I learned the trade and worked in sales, customer service, dispatch, and management. Seeing the business from those different positions helped me understand how much goes into a good client experience—and how much the people doing the work need from their company.
In 2018, Gonzalo Albarellos and I left our jobs and started THE Water Heater Company. We served our first client in January 2019. We saw an opportunity to build a business around water heater expertise, with a clear focus on the quality of the work and the way people are treated.
A place where people can build a future
The trades gave me an opportunity to build a career. I want the people who join our team to have that opportunity, too.
That means investing in training, setting clear expectations, and helping people develop the skills and confidence to take their next step. We ask a lot of our team, and we have a responsibility to give them the support to succeed.
I care about personal responsibility, integrity, and continuous learning because they shape how we show up every day. They affect how we handle a difficult conversation, respond to a mistake, and take care of a homeowner who needs our help.
That same thinking guides how we use technology. I see AI as a way to give our team better tools, make information easier to access, and free up time for work that needs their attention. The standard is whether it helps our people and improves the client experience. Personal connection still matters.
That’s the company I want to keep building: one where people take pride in their work, clients understand their options, and getting better is part of the everyday routine.
