Established in 1949 by the Tennessee General Assembly, Municipal Technical Advisory Service (MTAS) provides technical advice to cities and towns across the state of Tennessee: their governing bodies, mayors, city managers, city recorders, and city department heads. MTAS provides this assistance with consultants who specialize in most areas of municipal operations. MTAS annually completes more than 1,000 major municipal management projects and provides an average of 6,000 other services each year.

As an agency of the University of Tennessee and in collaboration with the Tennessee Municipal League, MTAS leverages the resources of the university to improve the lives of the people of Tennessee with technical consulting, research and training for municipal governments. MTAS is the resource for cities, towns and state agencies on municipal services and issues in Tennessee. MTAS assists Tennessee cities and towns with the training and information necessary to support informed decisions, and helps develop valuable solutions to the issues and concerns facing these communities.
