EOLIS's experience in corporate boardrooms spans more than five decades, beginning in 1971 with Wendeen H. Eolis's appointment as a special advisor to the board of Caesars World, after completing two attorney search assignments for the newly constituted public company. Since then, Wendeen has served as an ex officio Board member or advisor to the C-Suite: TransWorld Airlines, GAF Corporation, Citibank, AT&T, MGM, Columbia University, NYU Law School, Palo Alto Network, and PokerStars, among others.

Beginning in the late 80s, EOLIS occasionally did public company board searches. The practice was grown through the Company's better-known capabilities to vet lawyers and law firms for special counsel roles. By 2010 the Company was ready to roll out a new division: EOLIS Boardroom Advisory Services. It was designed to grow the Boardroom search and vetting assignments and to add boardroom preparation to the menu of attorney career transition services.

As Bloomberglawnews.com proclaimed in a 2023 article, we have reached "The Golden Age" for lawyers on boards. As an advisor to CEOs, Board chairs, and nom/gov committees, EOLIS is accustomed to identifying and presenting top-level legal talent with suitable "chemistry" for the particular board. The Company has been recognized, frequently, in other legal and boardroom publications. EOLIS is well-known as an advocate for lawyers on boards; guiding the best and the brightest into boardroom service.
