Welcome!

Welcome to the home of the Maricopa County Sheriff's Enforcemenet Support Posse. We appreciate the opportunity to tell you a little about our organization, what we do and how you can become a member or valued supporter.

501(c)(3) Non Profit Organization

Enforcement Support Posse is a registered 501(c)(3) non-profit organization. We have no paid staff or directors and receive no tax dollars. Our efforts are supported by member dues and donations from corporations and individuals in the county we serve.

What we are about and what we do

The Maricopa County Sheriff's Office Enforcement Support Posse (MCSO-ESP) is an all volunteer organization of specially trained men and women who serve the residents of Maricopa County Arizona by providing law enforcement support services to the Sheriff.

Patrol Assistance

Helping to keep our Deputies on Patrol. Encompassing over 9,200 square miles, Maricopa County is larger than seven states and the District of Columbia. With a population of over 3.7 million, it is the 4th most populous county in the country. Residents of the over 7,700 square miles (84.4%) of Maricopa County which is unincorporated, along with those in contract cities rely on MCSO for law enforcement services.

That’s a lot of ground for deputies to cover, especially in the rural and outlying areas. Just the process of transporting one arrestee and booking him/her into jail can take a deputy out or his or her beat for hours. Securing a crime scene or providing traffic control at an accident scene can keep a deputy out of service for even longer. Posse members routinely perform these duties allowing deputies to stay in their beats, thus reducing the response time when a resident of Maricopa County calls for help.

In addition, most deputies patrol their beats in solo cars. Help is often many miles away, forcing deputies to sometimes face dangerous situations alone and without backup. Specially trained Qualified Armed Possemen (QAP) also serve as partners for deputies and while on patrol can provide necessary backup to our deputies, helping to improve officer safety.

Special Duty Assignments

Posse members may also be assigned to special details which may be planned and/or recurring community events or which may be required as a response to unanticipated emergencies. A few examples of Special Duty Assignments are:

Crowd/Traffic control and security for planned community events such as parades, fairs or sporting events.
Assisting in law enforcement operations required in the event of natural disasters.
Assisting in searches for lost persons.
Working at child fingerprinting/identification events requested by schools or other community service organizations.

Assisting in law enforcement operations required for events related to Homeland Security at the community level.
