Mike King, Owner of SiteCon Exteriors

With over three decades of hands-on experience in the construction industry, Mike King brings a unique blend of vision, craftsmanship, and leadership to every project. As the Owner and Director of Creative Implementation, Mike leads with a deep understanding of what it takes to turn a concept and idea into a lasting, fully functional plan for implementation that focuses on ultimate teamwork and delivering the best quality product for the end user.

Mike’s journey began in the field—literally—with roles as a craft laborer in both commercial and residential settings. That ground-up perspective has shaped his holistic approach, one that values collaboration, precision, and integrity. Over the years, he’s worn many hats: field supervisor, preconstruction lead, project manager, and consultant. He’s contributed to major projects through respected general contractors like The Neenan Company and DPR Construction, as well as through independent subcontracting and advisory roles.

Today, Mike is focused on delivering high-quality site concrete, site furnishings, and landscaping that not only meet but elevate expectations. His passion lies in building spaces that are both beautiful and built to last—where every detail reflects a commitment to craft, people, and purpose.

Jason Losey, Field Operations Manager

With over 24 years of experience in both commercial and residential construction, I specialize in concrete installation and a wide range of concrete-related disciplines. Throughout my career, I’ve worked in multiple leadership roles including Concrete Finisher, Carpenter/Form Setter, Leadman, Foreman, Assistant Superintendent, and Superintendent, overseeing complex and high-profile projects from planning through completion.

I’ve had the opportunity to contribute to major construction efforts with some of the industry’s leading companies, including DPR Construction, PERI Formworks, Big-D Construction, Baker Concrete, and Coloscapes Concrete.

My hands-on experience spans data centers, tilt-up construction, flatwork and paving, and structural/vertical concrete work. Some notable projects I’ve been a part of include: QTS Data Center, Hawaii Navy EASE, Holocaust Museum (California), Alamogordo Air Force Base, Alliant Energy Data Center, American Family Insurance Headquarters, Good Samaritan Hospital.

Known for a results-driven approach and strong leadership on-site, I bring both technical skill and project coordination expertise to every job, ensuring quality, safety, and efficiency at every stage.

We specialize in site concrete and outdoor infrastructure that supports public use—things like benches, bike racks, planters, and concrete design for parks, schools, and commercial spaces.

With decades of combined experience, our team understands what it takes to build for the outdoors. We focus on durability, function, and fit—installing products that hold up in high-use environments and match the surrounding design. Whether we’re pouring decorative concrete in Colorado or a mile of curb and gutter in Arizona’s searing heat, our goal is always the same: to deliver a quality product, every time.

We work closely with general contractors, architects, and municipalities to keep projects on schedule and within spec. Our knowledge of local codes, materials, and site conditions helps reduce delays and unexpected costs.

SiteCon Exteriors brings practical, field-tested insight to every project. From layout to installation, we manage the details so you don’t have to. We understand the pressure that comes with public and commercial builds, and we’re used to working under tight timelines.
