The HdL Companies began their legacy of service to public agencies as Hinderliter, de Llamas & Associates in 1983. The company's founder, Robert Hinderliter, a city manager and finance director, developed California's first comprehensive sales tax management program and secured legislation allowing for independent verification of state allocations. Building on that foundation, The HdL Companies now partner with local governments nation wide, providing a full assortment of public agency revenue management services including sales tax, property tax, lodging tax, business license and tax, cannabis regulation and tax, economic development and more.
