Lish Costigan traces her roots back to the Jersey Shore, with detours through Hartford, Rome, Hoboken, and the bustling streets of NYC, before finding her way back home. Amidst the whirlwind of raising her three lively children—Eila, Everly, and Cormac—Lish also navigates the realm of remote work, contributing to the growth of Ernst & Young’s Financial Services Organization. And if you're wondering where her kids get their boundless energy, just look to her Irish-born husband, Conor, straight from the heart of Tipperary.


At EY, Lish leads a team overseeing a market exceeding $4 billion, lending strategic and tactical support to the firm's go-to-market initiatives, particularly in the Banking and Capital Markets sector of NYC. Essentially, she's a hybrid of marketer, data analyst, and sales strategist, adept at transforming client ideas into actionable strategies tailored to their unique needs. Lish's ability to synthesize disparate concepts and discern trends allows her to craft bespoke solutions that drive results, both in her professional sphere and in her personal endeavors.

Beyond her corporate role, Lish finds fulfillment in collaborating with non-profit organizations, bridging connections between volunteers, board members, and corporate sponsors to further community engagement efforts. She revels in the convergence of purpose and influence, eagerly anticipating the transformative impact that the Female Forward Alliance (FFA) will bring to their local community.
