The firm was founded in 1997 to service tribal governments with regard to benefits law and taxation issues. The founder, Robert R. Yoder, began working with tribal governments almost 24 years ago, at a time when very few tax practitioners were focusing on tribal government issues. At that time, he realized that tribal sovereignty was being waived in many cases because tax practitioners were not familiar with sovereignty principals, the unique laws and doctrines that apply to tribal entities, and the government to government relationship between the federal and tribal governments. 

Yoder & Langford now represents approximately 40 tribal governments and entities throughout the country from California to New York. 

The firm's mission is to advise governments on employee benefits, taxation law, trust, and health care issues in a manner that will coordinate federal regulation with governmental sovereignty.

Yoder & Langford also represents municipal governments with regard to the tax compliance aspects of their public pension plans. ​
