Senior Advisor Program

The ICMA Senior Advisor Program (formerly Range Rider Program) was established in 1974 through the efforts of ACMA Life Member Mark Keane and the ICMA Board. The primary purpose was to make the counsel, experience and support of respected, retired members of the profession available to local government managers. It was felt that being the top administrator in local government was sometimes a lonely business; at least with respect to the availability of persons for discussing certain kinds of management, political or even personal problems. That is, there might be no one appropriately available in his or her staff or council. Thus the Range Rider concept was born as one answer to this need.

In addition to consulting with managers, Senior Advisors respond to calls for assistance by cities that are interested in adopting the council-manager plan or to consult with charter commissions who are studying changes to their charter regarding the duties of a city manager. Also, they have assisted in defending the council-manager plan.

In 2013, ICMA Executive Director Bob O’Neill appointed a 2014 Advisory Committee to celebrate 40 years of the Range Rider Program and to enhance its value to ICMA members and to state associations in the second century of ICMA. The Advisory Committee’s recommendations to “refresh” the program for the future were approved by the ICMA Executive Board in February 2014.

A number of recommendations reinforced current guidelines. Recommendations for change or greater clarity included encouraging terms and periodic reviews for Senior Advisors in order to ensure continued vibrancy and effectiveness, making non-CAOs eligible for appointment as Senior Advisors, modifying the conflict of interest guidelines to allow more members engaged in part-time consulting to serve in the program, a statement of policy to clarify any Senior Advisor involvement in manager placement work and steps to foster performance and accountability for all three parties to the program, Senior Advisors, state sponsors and ICMA. The recommendations included a change in the name from Range Riders to Senior Advisors to better describe the role and its primary emphasis on providing members with advice and support. Those members who were serving as ICMA representatives to state associations and other groups. This change in titles became effective at the 2014 ICMA Annual Conference.
