Wm. Teitsma Construction (WTC) is a Commercial and Industrial Construction Management, Design Build, and General Contracting firm. We are dedicated to delivering predictable and valuable building solutions throughout Northern New Jersey and Eastern Pennsylvania.

Founded in 2010 by William “Bill” Teitsma III, WTC was built on a simple principle: your goals become ours. Bill’s hands-on leadership from jobsite coordination to strategic planning has established a foundation of trust with owners, architects, and project partners alike.

Over the years, WTC has grown into a reliable partner known for thoughtful planning, clear communication, and execution discipline across commercial and light industrial projects. We use a collaborative approach that emphasizes early engagement, helping teams refine designs, manage risk, and control costs before construction begins. This preconstruction leadership is core to how we create value.

As an authorized Nucor Builder, we also specialize in pre-engineered metal building systems, to deliver cost-efficient, customizable structures with the performance and flexibility our clients need.

Today, with the next generation joining the leadership team, we’re pairing deep industry experience with fresh operational insight to help owners and design teams navigate complex projects with confidence.

At WTC, we don’t just build buildings. We build trusted partnerships that deliver predictability, transparency, and long-term value
