Built on Pride.
Committed to Excellence.
At Tenax Electrical, we believe that great work starts with great people, and great people deserve to have a real stake in the success they help create.

An Electrical Contracting Company Where Every Connection Matters
Employee success means every person at Tenax Electrical has both a personal stake in our shared success, driving a commitment to deliver outstanding work. When you’re invested in the outcome, it shows, in the care we bring to every project, the trust we build with every client, and the pride we take in doing the job right.
Built on Experience. Driven by Purpose.
Tenax Electrical is a new kind of electrical contracting company, founded by industry veteran Dave Yencarelli to raise the standard for quality, safety, and service in the Jacksonville and North Florida region. With over two decades of experience managing complex electrical projects, Dave launched Tenax Electrical to build a company where integrity, craftsmanship, and people come first. His vision: create a culture that empowers electricians and staff to take pride in their work, invest in their growth, and deliver exceptional results on every job.
Dave’s journey began on an orange grove in Central Florida, where a summer job wiring irrigation pumps sparked a lifelong interest in electrical work. He went on to earn his electrical certification, and over the years took on leadership roles overseeing large-scale projects across Florida, Georgia, Alabama, and the Carolinas. His portfolio includes multimillion-dollar transportation centers, airport infrastructure upgrades, commercial developments, and major public works projects.
Tenax is the next evolution of that journey.
At every stage, Dave has led with the belief that investing in people, through training, trust, and shared responsibility, is the key to successful outcomes. That same philosophy is now at the core of Tenax Electrical.
In addition to leading Tenax, Dave remains deeply involved in the industry and our local community. Tenax may be a new name, but it’s built on proven experience, strong values, and a long-term commitment to excellence.
A Culture of Shared Responsibility
When every team member is valued, decisions are made carefully. We approach every project with the same question: “What would we want if this were our own business, our own building, or our own home?” This mindset drives smarter solutions, better project outcomes, and stronger relationships with the contractors, businesses, and homeowners we serve across Northeast Florida.
