Bob's prior experience as senior advisor to an Arizona Congressman provided a unique understanding of Native American, transportation, funding and other issues that has been a great asset in his representation of clients for the firm.

Bob works on a variety of issues at the federal level related to Native American issues, appropriations, transportation, tax law, telecommunications, energy and natural resources. He has been responsible in obtaining more than $200 million in federal funding for the firm's various clients, including funding for various infrastructure projects such as flood control projects, transportation, transit and airport projects. He has successfully shepherded multiple bills into law including fair tax treatment for Alaska Natives (public Law 107-016), the conveyance of irrigations canals from the BIA to the SRP-MIC (Public Law 106-568), binding arbitration for all contracts on tribal lands (Public Law 108-329), and the Yavapai land exchange (Public Law 109-110) that personally benefited the firm's clients.

Prior to his service with Nexxus Consulting and Landry-Creedon, Mr. Holmes spent six years with Congressman J.D. Hayworth working on a variety of issues related to Indian country and Arizona, including appropriations, transportation, telecommunications, and energy and natural resources. Mr. Holmes was instrumental in the formation of the Native American Caucus, a non-partisan Congressional Member Organization (CMO) to educate Members of Congress about the important trust responsibility the federal government has to Native Americans. He has been serving Arizona interests since 1995.
