Hill & Robbins has taken on significant pro bono litigation and helped to organize several nonprofit entities. The firm defended Colorado's Amendment 15 (GAVEL amendment) and Amendment 16 (campaign-finance reform initiative) on behalf of Colorado Common Cause and the League of Women Voters as well as representing those same clients in litigation involving campaign finance reform. Members of the firm were co-founders of Invest in Kids, an organization that provides early intervention programs for at-risk children and families, and Project Safeguard, an organization committed to advancing the legal rights of victims of domestic abuse.
