Marin Gjaja

Senior Partner & Managing Director


Marin Gjaja is a member of The Boston Consulting Group’s Consumer and Health Care practices. He has also worked in every one of the firm’s functional practice areas. He leads BCG’s six offices in the US Great Lakes region and Canada, directly manages the Chicago office, and previously led the global consumer products sector and Midwest Health Care practice.

Since joining BCG in 1996, Marin has worked primarily with companies in the consumer goods and health care industries. For clients at the corporate and business-unit levels, he has developed and put into effect value-maximizing strategies, such as those for organic and inorganic growth, and often worked with the clients to help the strategies succeed. This assistance has included supporting implementation and building the capabilities—for example, margin optimization, turnarounds, and even divestitures—needed to make the success sustainable.

Marin has led multiyear transformation efforts for global clients, helping them drive change and value across multiple initiatives simultaneously. This work has touched on areas such as procurement improvement, organizational restructuring, optimization of pricing and trade spending, portfolio pruning, working capital, and manufacturing and supply chain. Marin also has deep understanding of issues related to innovation capabilities, bettering route-to-market, product launch, consumer marketing and branding, optimization of spending on marketing, leadership, culture, and change management.

Before BCG, Marin was a researcher at Boston University and was selected as an alternate on the 1992 US Olympic Men's Volleyball Team.
