“Siegel Long Public Affairs consistently and competently delivers the kind of advice, access and advocacy we need to make our legislative agenda as successful as possible. Carolyn and her team are more than great lobbyists, they are partners with us on moving our agenda to improve economic justice for all Coloradans.”
— Carol Hedges, Former Executive Director, Colorado Fiscal Institute
“Working with Siegel Long Public Affairs has made a big difference for our organizing efforts. We have been able to reach key elected officials to both educate them about the issues that are impacting our members and engage them in our work to move forward policies that will create the change we want and need to see happen. Carolyn and the rest of the team work diligently to ensure we are advancing our organizational goals and to bring the experiences of our members to the center of the legislative process. ”
— Lizeth Chacon, Former Executive Director, Colorado People’s Alliance (COPA)
