Founder | Owner

I started my electrical career in 2005 in the commercial field. The first project I had the honor to start on was the W hotel in Downtown Dallas. I have commercial, industrial, and residential experience. But I enjoy residential the most.

I attended IEC from 2005 thru 2009. Ever since I was introduced to this field, I have absolutely loved it. Even to this day, I enjoy waking up every morning to do what I love to do. Every day is a new challenge and every day is a new adventure. But regardless of the obstacles, I enjoy learning new technologies, especially in the electrification field!

I am happily married to my lovely wife and business partner, Anakaren. We have 3 handsome boys, Damian, Gabriel and Emilio.

DFW Operations Manager / Lead Service Technician

I grew up in the industry. My father was a master electrician from 1975 until he passed in 2022. My family (uncle) also built custom high-end homes in the Hamptons, New York, so I was trained in high-end building and wiring techniques.

I’m a Lutron certified smart home installer, as well an LED lighting expert for both inside the home as well as landscape lighting. I am also a SPAN certified installer and whole-home battery expert. I am the type of person who is always learning something new and I’m not afraid of a challenge.

My wife Heather and I have three beautiful girls, Keira, Eleanor and Camille. When I’m not at work I’m with them. My number one job is to be the best dad I can for my girls. It’s what makes me start off every day with a smile and a positive attitude. I truly believe that EPX is striving to be the experts in our field of work.

“William is simply the best. My wife and I have been undertaking a remodel that has taken a year and a half to complete and we have had many highs and lows. But out of the highs one stands out, and that was William. He is professional, courteous, respectful, fair, and fun to boot. He rewired our entire house and did an amazing job. Our jobsite is a couple hours away from where William lives but he was willing to drive several hours to and from to honor a small warranty issue (a small breaker was a lemon, nothing related to workmanship) and did so with a smile. To this day I can call him up if I need to troubleshoot something and he remembers exactly how he wired my entire house from memory and is always willing to walk me through anything. Again, simply the best. Though we probably won’t go through such an extensive remodel ever again, if we do, the first person we are calling is William.”
