West Monroe Acquires CAST Management Consultants

West Monroe Partners, a full-service business and technology consultancy, today announced the acquisition of CAST Management Consultants, a Los Angeles-based consulting firm specializing in performance optimization solutions for the financial services industry. CAST, founded in 1986, serves many of the nation’s largest retail and commercial banks and insurance companies. 

Nearly 20 CAST employees join West Monroe Partners’ Financial Services practice. These include CAST’s President and CEO, Thomas Collins, and Executive Vice President, Christopher Caulfield, who will become directors based in the firm’s Los Angeles office.

“The addition of CAST bolsters our fast-growing local practice with accomplished consulting professionals who strengthen our financial services subject matter expertise and provide a strong fit with our culture and business priorities,” said Ken Siegman, senior director and leader of West Monroe Partners’ Los Angeles office. “Together, we can bring valuable new resources and insights that will help our respective clients adapt quickly in an increasingly complex financial services environment.”

The acquisition combines West Monroe’s deep technology expertise and knowledge of commercial lending and treasury services process optimization with CAST’s capabilities in commercial banking delivery model design, data-driven organizational transformation, retail banking digital channel optimization, and leading-edge risk and regulatory solutions. Both firms have deep expertise in commercial lending, digital/customer experience solutions, mergers and acquisitions, and treasury management. The transaction also expands West Monroe’s Los Angeles team significantly.

“CAST’s leaders and team immediately extend our financial services depth and breadth and our credentials for serving the nation’s leading banks,” said Gil Mermelstein, managing director and leader of West Monroe Partners’ Financial Services practice. “Our teams share many strengths as well as complementary capabilities, all of which provide differentiated expertise that is essential to our goal of helping clients evolve their operating models and technology to a customer-centric digital future.”

“We feel strongly that the solutions we will be able to deliver to our respective clients as a combined entity will be unparalleled. We are eager to bring our experience and capabilities to West Monroe Partners to create a world-class consultancy that will provide services across the spectrum, from strategy to process to technology to operating model design,” said CAST’s Collins. “At the same time, West Monroe Partners’ unique people-oriented culture, tremendous growth, and emphasis on building the next generation of leaders meshes well with our strong existing culture and translates to enhanced career opportunities for our professionals.”
