November 12, 2026

WASHINGTON, D.C. – Dewey Square Group (DSG) today announced that Michael Mandell, a veteran campaign operative and public affairs consultant, has joined the firm as a Principal and Practice Leader. A longtime collaborator of DSG, Mandell will oversee the firm’s new Campaign Practice, bringing more than 15 years of experience managing political campaigns, serving in government, leading high-stakes corporate affairs efforts, and building coalitions in support of clients’ objectives.

“Michael has been a trusted partner to Dewey Square for years, and there’s no one better suited to lead the Campaign Practice,” said Michael Whouley, CEO and Co-founder of Dewey Square Group. “This year’s election showed voters want their elected representatives to find solutions to the issues and struggles they face day to day. The electorate is highly engaged. Now is the right time to bring Michael’s expertise in-house to help our clients mobilize support for policy-driven initiatives and causes.”

The Campaign Practice offers multidisciplinary campaign services to clients at the national, state, and local levels. Working with DSG’s related practice groups, Mandell will help clients build support for their organizations’ objectives through research, message development, data analytics, rapid response, and paid, social, and earned media, combined with on-the-ground grassroots expertise.

“Today’s public affairs challenges demand campaign-level discipline, which means sharp messaging, smart data, and real grassroots infrastructure,” said Charlie Baker, President and Co-founder of Dewey Square Group. “The Campaign Practice gives our clients all that under one roof.”

Mandell most recently served as Founding Partner of Hartford-based Intersect Public Solutions, where he advised clients on public affairs initiatives and campaigns from 2019 until joining DSG. Before that, he served as Executive Director of the Connecticut Democratic Party, Connecticut State Director for Hillary for America during the 2016 primary, and Policy Advisor in the Office of Governor Dannel P. Malloy. He holds a B.A. in Political Science and Economics from Tufts University. Mandell is based in Glastonbury, Connecticut.

“I’ve seen firsthand what Dewey Square’s team can do, and I’m thrilled to make it official,” said Mandell. “I look forward to building a Campaign Practice that helps our clients win support for their goals at every level and in every market in which they engage.”
