Consultants can provide a wide range of services, and are popular options for public art programs that operate with minimal staff or need an outside voice to offer advice about program direction, policies, or efficiency.  Often, public art consultants assist with program reviews and help shape and define the larger objectives of a public art program.  They can offer technical and practical expertise to accomplish those goals, and help create plans for the long-term success of a public art program.  Consultants can also be deployed to help educate other parts of a municipal government about the role and purpose of public art—another instance in which an outside voice may be able to have a greater impact.
