You’ll feel the difference working with us.
What sets ALLCON apart is the way our team shows up with pride in the craft, respect for one another, and a shared commitment to doing things the right way. By keeping general contracting, electrical, and carpentry expertise under one roof, we stay closely connected to the work and accountable at every stage. That hands-on approach, combined with our certifications as a woman-owned, minority, small, and disadvantaged business, reflects not just who we are, but how we operate creating opportunity, building trust, and delivering quality you can see in every detail.
ALLCON was founded in 2009 by Ana Lopez with a vision to build something different. A company rooted in integrity, driven by perseverance, and powered by people who truly care. From its beginnings in electrical work, ALLCON has grown into a self-performing general contractor trusted across Wisconsin for municipal, commercial, and federal projects. With in-house teams and a hands-on approach, the company takes pride in doing the work right, building lasting relationships, and earning trust through every project.
