Jerry Biggs

Jerry Biggs, President, CEO Linked In

As president of ProTerra, Jerry Biggs serves as the company's visionary. That ability was honed during Jerry's twenty-five years at the helm of the CPA and management consulting firm he co-founded. As the firm grew to be the third largest in Colorado Springs, Jerry was instrumental in providing tax and business guidance to its real estate and construction clients. He developed an expertise in formulating deal structures that were both innovative and technically sound. When the firm's clients faced challenges during downturns in the real estate market, Jerry served as their advocate by facilitating the negotiation of favorable workout solutions. By the time Jerry relinquished control of the firm to a successor in 2007, he had solidified his reputation as an accomplished real estate consultant.

As a complement to his consulting activities, Jerry has been an active real estate investor for his own account for decades. Jerry has continued his investment activities since leaving the firm, leading to his co-founding of ProTerra in 2013. Jerry is also an investor in a number of other privately held companies that operate in the real estate and construction industries and is actively involved in providing management oversight to those ventures.

Jerry continues to serve on the boards of various trade and charitable organizations and has served in key positions in economic development entities at both the local and state level. In addition, Jerry has received numerous awards for community service, including being named the 2010 El Paso County Community Leader of the Year.

Jerry's vision for the future of ProTerra is centered on deliberate strategic growth designed to maximize market opportunities and provide valuable solutions to its customers, while safeguarding the interests of the company's stakeholders.

Andrew Biggs

Andrew Biggs, Chief Operating Officer Linked In

A graduate of Colorado State University's construction management program, Andrew Biggs began his career as a project manager for a Denver-based construction subcontractor whose focus was residential subdivision. That position allowed Andrew to gain valuable practical experience in construction management, including estimating, scheduling, budgeting, and job costing, as well as field supervision. Andrew parlayed that experience when he joined his father in investing in a company that specialized in the spraying of trees to protect them from infestation by the mountain pine beetle. During their period of ownership, Andrew was integrally involved in expanding the company's operations beyond Colorado into multiple surrounding states and achieving a resulting threefold increase in the number of trees serviced. Upon the profitable sale of the company in 2013, Andrew once again teamed up with his father as a co-founder of ProTerra.

Andrew brings youthful energy and passion to his position as the Chief Operating Officer for ProTerra. In addition to overseeing and coordinating field operations, Andrew is instrumental in securing necessary entitlements for the company's projects as well as sourcing and determining the feasibility of potential projects. Andrew looks with confidence toward the company's future and his continued role in managing the profitability and timely completion of its projects.
