About Juan Carlos

Juan Carlos has a substantial track record of leading high-profile company transformations. As a former CEO, he has addressed broad strategic challenges—including turnarounds, sizable mergers, and large start-ups—and charted a course to stronger growth. He brings this experience to his work with McKinsey, helping companies facing performance and transformational challenges to undertake major improvements.

Before joining McKinsey, Juan Carlos was CEO of Inmobiliaria Aconcagua, one of the largest real-estate companies in Chile, where he led an effort to more than double net income. Before that, as CEO of the LATAM Airlines South America division, he led the integration/merger between the South American business units of Chile’s LAN Airlines and Brazil’s TAM Airlines into a combined $2 billion business that was profitable from the first year of the merger.

He also has extensive experience serving as a board member and chairman of the board in companies in Argentina, Chile, and Paraguay, including, among others, serving as a member of the board of Sky Airline, where he helped to transform the airline into a successful low-cost carrier; chairman of the board of TAM Airlines Paraguay, where he led the airline from losses to profits; and chairman at Banco Industrial Argentina, where he helped take the bank to the next level of performance.

Since joining McKinsey, Juan Carlos has been an active member of our RTS Practice, supporting executives in successful performance improvement and operational transformation. In particular, he has worked in the basic-materials sector, helping to address strategic and operational challenges for a South American mining company. He also led a top-down assessment of the P&L opportunities for one of the larger airlines in South America and worked with a large oil and gas company to reduce its cost base.
