Our Team

Our employees are highly trained and experienced professionals who are recognized leaders in their technical disciplines.

Individual qualifications include the Professional Engineer (P.E.) and Professional Land Surveyor (PLS) licenses. Both licenses are granted by the State of Colorado after examination and proof of the required education, qualifications, and experience. Generally, this includes a four year technical degree, at least four years of discipline-relevant experience, and passing both the E.I (Engineering Intern) or LSIT (Land Surveyor in Training) and P.E. or PLS exams.

All engineering plans, specifications, and reports and surveying plats, legal descriptions, and boundaries must be prepared under the responsible charge of a Colorado-registered P.E. or PLS., respectively.

Our staff have earned other designations reflecting advanced professional training including Certified Floodplain Manager (CFM), Leadership in Energy and Environmental Design Accredited Professional (LEED AP), and Certified Public Accountant (CPA), along with advanced technical degrees, training, and coursework.
