ASA Architects, P.A., one of the largest architectural firms in the Southern New Mexico/West Texas region. Established in 1968, the firm offers comprehensive architectural services, specializing in public projects and educational facility design. Founded in Roswell, New Mexico, as Alley & Associates, the firm was renamed Alley Mendez Shelton in 1988, and in 1992, became ASA Architects. The company’s corporate office, headed by president, Ted Shelton, is located in the downtown area of Las Cruces, New Mexico. In the course of serving clients in West Texas, ASA opened a satellite office in El Paso in 1989. ASA also has an affiliate office in Zacatecas, Mexico.

ASA’s mission is to provide a consistently high level of service. We place the highest priority on client relations and strive to maintain the close personal style of a small company while offering the substantial capabilities of a large firm. With every project, regardless of size or scope, ASA’s aim is to develop plans that match the client’s needs, objectives and resources. By striving to match these goals and cultivatinglong-term relationships with clients, ASA Architects develops designs that provide superior project satisfaction and a positive influence on the client’s surroundings and community.
