About CSG West
A Regional Partner to Western Legislatures
Founded in 1947, CSG West is a nonprofit, nonpartisan organization serving state legislators and legislative staff across the Western region. As one of four regional offices of The Council of State Governments, CSG West provides a platform where policymakers connect across state lines, foster the exchange of ideas, and advance solutions shaped by the West’s geography, resources, and growth.
Addressing the West’s Shared Challenges
Western states face interconnected challenges—from water management and wildfire resilience to energy systems, housing pressures, and cross-border policy. Through regional convenings, policy-focused initiatives, and sustained engagement across state lines, CSG West strengthens legislative institutions by fostering collaboration, informed dialogue, and regionally grounded approaches to shared challenges.
Developing Effective Public Leaders
Developing effective public leaders is integral to CSG West’s mission. From the Western Legislative Academy to staff-focused trainings and in-state workshops, CSG West equips public servants with the skills, perspective, and institutional insight needed to lead effectively and navigate the evolving responsibilities of public service.
Connected Regionally. Supported Nationally.
CSG West is uniquely positioned as the only CSG region with dual international borders. Reflecting the interconnected nature of the Western states, the organization convenes programs that examine cross-border issues and binational collaboration affecting state policy. This regional perspective informs conversations on trade, natural resources, economic development, and other issues shaped by the West’s geographic and economic landscape.
CSG West is one of four regional offices of The Council of State Governments, the nation’s only nonprofit organization serving all three branches of state government. Through this broader network, members gain access to a national platform, data-driven expertise from the CSG Justice Center, technical support from the National Center for Interstate Compacts, and collaboration with 11 national affiliate organizations. These resources complement CSG West’s regional focus while amplifying the effectiveness and influence of Western state leaders.

Our History
Henry Wolcott Toll was a Colorado state Senator who believed that if states wished to maintain control over inherent state issues, interstate cooperation was imperative. The strength of his conviction led him to establish what was once the American Legislators Association in 1925 with one straightforward goal: to provide elected state legislators with information and opportunities to connect. Enjoying significant success, the effort evolved. Senator Toll and a dozen colleagues formally established The Council of State Governments (CSG) in 1933 as a national organization serving all three branches of government. Initially based in Chicago, Illinois, CSG moved its headquarters to Lexington, Kentucky in 1967 – where it remains to this day – providing essential leadership nationally and to the regional operations at CSG East, established in 1937; CSG Midwest, established in 1945; and CSG West and the Southern Legislative Conference, both established in 1947.

Our Governance is Member Driven
Governance of CSG West is run with member needs top of mind, particularly given the weighty responsibilities of our members. Composed of Executive Committee members, officers are elected annually and rotated to ensure a bi-partisan approach in their direct oversight of the organization’s work. Acting as our governing board, the Executive Committee is made up of legislative leaders from each state and meets each year during the CSG West Annual Meeting – our marquee event — to review the work of CSG West policy committees, adopt policy positions and recommendations, and review the ongoing development and effectiveness of the organization.
