About us


Coming together to build what matters.

  • Team Q
    Creative collaboration, familial spirit, and an appreciation of hard work and commitment are the driving forces behind Team Q. Team members rely on each other and on their interpersonal relationships with clients, owners, and trade partners because each are essential elements in completing a successful project. Together, they build a foundation stronger than that of any building or structure. They build the future.

Our History

Questar’s beginnings are grounded in state-of-the-art healthcare facilities. Today, Questar holds a reputation of excellence and integrity, continuing to expand its expertise in various areas of construction since 1979.

Questar’s successful projects range from small tenant improvements and large box tilt-ups to multi-million dollar ground up facilities in the following areas:

  • Commercial
  • Industrial
  • Historical
  • Retail
  • Educational
  • Healthcare

A family owned business, Questar’s philosophy revolves around building a better future for its clients and community, with respect and admiration of the past. As such, Questar takes pride in managing and building projects that require attention to the preservation of structures, spaces, and client operations.

Our Mission

Questar’s mission is to take projects from ideation to creation, building structures and spaces for people to learn, heal, create, and live.

Questar has firmly constructed its work environment to center on teamwork and team cohesion; ‘Team Q’ we call ourselves. Each member contributes to Questar’s overall mission to bring fresh ideas and innovation to each area of its projects and operations.

With one of the lowest management turnover rates in the industry, Questar team members use their existing knowledge as well as project knowledge to anticipate challenges, develop creative solutions, find potential engineering opportunities, avoid delays, and eliminate budgetary concerns.
