LANSING, Mich., July 30, 2019 — Sterling Corporation, a division of Lambert & Co., has engaged former Michigan State Senator John Proos as a strategic consultant to support the firm’s growing roster of clients. Building on his nearly 25 years of public service, Proos united his expertise in public affairs and strategic counsel to create JP4 Government Solutions, which provides insights for corporate, manufacturing and not-for-profit entities.

“John’s wealth of knowledge regarding Michigan legislature is truly second to none,” said Heather Lombardini, president of Sterling. “Our team and our clients will be well served by John’s unmatched reputation and his deep understanding of public policy.”

In 2018, Proos completed 14 years in elected office after spending two terms representing the 21st district in the Michigan Senate and three terms as the state representative for Michigan’s 79th House District. Prior to becoming an elected official, Proos served under Congressmen Fred Upton as deputy chief of staff and district director.

“I am excited to work with Sterling in this capacity, and with the broader Lambert team statewide,” Proos said. “In this new role, I hope to offer a unique perspective and help clients make informed business decisions to achieve their goals.”

In addition to providing counsel to Sterling’s public affairs clients, Proos will also work with clients from Lambert’s roster. Michigan’s largest public relations, public affairs and investor relations firm, Lambert has a client portfolio that includes global automotive and mobility suppliers, national consumer brands, healthcare leaders, education and social impact organizations and the public sector. The firm is listed as a national top-50 PR firm, top-10 financial and investor relations firm, and top-10 environmental and public affairs firm by O’Dwyer’s.

“John’s policy-focused lens, coupled with his stellar reputation as a hard-working and trusted leader, is a strong complement to our services at Sterling and Lambert,” said Jeff Lambert, founder and CEO of Lambert. “I look forward to incorporating his counsel into our work for clients across both firms.”
