Message From Our CEO

AZTEC is privileged with the fortune to have provided professional consulting services for various public and private clients since our Phoenix-based company was established in 1992. From this beginning, we expressed gratitude not only to our clients that provided the opportunities to deliver successful projects, but also our employees (past and present) that dedicated their careers to providing high-quality and exceptional services that shaped the company culture which thrives today. We’re very proud to have served many clients for planning, permitting, designing, and constructing infrastructure projects that support many local communities we work and live in. Now with our parent company, the TYPSA Group, we offer global consulting services with experience in over 35 countries world-wide.

Our professionals take great pride to comprehending the client’s needs which in turn allows us to provide cost-effective quality solutions and services in a flexible, timely manner. We do this through team dedication, proactive communication, professional integrity, and service excellence. As a result of our service-oriented goals, AZTEC continues to expand our market share in the US.

For many of the reasons mentioned above, I am very pleased to inform you that Engineering News Record (ENR) has awarded AZTEC with the distinction of being named the Southwest Design Firm of the Year for 2015.

Thank you for taking the time to visit our site. We hope you now have a better understanding and appreciation of what makes AZTEC a consulting firm you want to work with. Please feel free to contact me to discuss how AZTEC can assist you with your project.
