West Monroe creates tangible financial value for our clients. As chief commercial officer, Casey is pivotal in this mission. With over a decade of experience collaborating across all aspects of the organization—and with clients—she now leads the team that sets West Monroe’s strategic direction, ensuring our work not only helps clients capture the value of being digital but also aligns with the firm’s long-term vision. This means anticipating issues that our clients will face on the road to digital leadership—and building repeatable offerings, products, and technology assets that efficiently address these challenges, ensuring clients see measurable impact sooner. Casey’s role extends to leading the firm’s strategy and execution for partnerships with major players like Salesforce, nCino, Alteryx, and Databricks. These partnerships not only provide West Monroe’s clients with access to essential technologies but also serve as a mutually beneficial growth channel. As a member of West Monroe’s Executive Team, Casey’s insights and market intelligence are central to defining the firm’s strategy. Her innovative approach shapes how West Monroe ‘shows up’ for clients, both in actions and impact. Under her leadership, the firm has developed a framework for innovation, leading the charge in bringing groundbreaking results to the market. She joined West Monroe from Discover Card in 2008, assumed leadership of the marketing function in 2011, and was named chief marketing officer in 2019. As a leader, she elevated and differentiated the firm’s brand and guided programs that have had a direct impact on West Monroe’s ability to grow at a rate of 30% annually. She has a B.S. from Boston University and an M.S. from Northwestern’s Medill School of Journalism. Casey thrives amid fast-moving change – always looking for the next hill to climb. She enjoys mentoring and building the next generation of leaders who are ready for a high-intensity journey. She applies this drive and determination in her personal life, as well, as a Peloton fanatic. Passionate about building the consulting firm of the future, Casey constantly seeks opportunities to create value for clients and encourages her teams to do the same. Her personal commitment extends to philanthropy, actively supporting pancreatic cancer research and early detection efforts in memory of her mother and serving on the board of Girls on the Run Chicago.
