Established in 1996, AG|CM is the premier construction management firm in South Texas. AG|CM was founded by Derwood Anderson to manage large capital construction projects for institutions, municipalities, industrial and commercial entities that do not have the expertise or staff to properly administer such complex projects.

During the first 17 years of his career, Anderson worked for several large, prominent general contractors, where he acquired an in-depth knowledge and perspective of the construction process. Similarly, he observed the interactions between architects/engineers and the owners of projects, and concluded that both groups ultimately had vested interests they protected during the design and construction process that may not match those of their clients. This observation led him to conclude that owners truly needed an advocate, a group with strong leadership and decision-making skills that would enter into a relationship with the owners and work solely for their interests. Thus, AG|CM was born.

Gail Anderson has served on the Board of Directors since the firm’s inception in 1996 and joined AG|CM as chief executive officer (CEO) in 2006. Anderson draws from her visionary planning and resource management skills and 30 years’ experience as a professional engineer to advance the company’s growth in new markets throughout Texas and the southwestern states.

Today, AG|CM has also established itself as a leader in preconstruction services, especially estimating. With national and international projects under our belt, our highly educated, experienced, certified and detailed-driven team incorporate proven innovative technology and trusted resources to supplement our years of experience when developing our estimates.

With a reputation for working in the client’s best interests and finding ways to resolve even the toughest of issues, AG|CM’s success is directly attributable to the guiding principles conceived by Derwood and Gail Anderson and carried out by a staff dedicated to serving the owner’s interests, as evidenced by our exceptional reputation, repeat business and accolades by owners and contractors alike.
