stephen corsiGlobal tech agency Lewis has elevated Stephen Corsi to lead its US operations with the exit of 20-year alum Morgan McLintic.

Corsi joined the firm in 2012 from digital shop iCrossing and has been focused on developing the firm's digital marketing unit, Lewis Pulse. He was previously in marketing and communications in the financial sector.

McLintic, who is opening his own firm, started with Lewis in London in the mid-1990s before moving to the US as the firm built from the ground up in San Francisco to a 300-staffer US team.

Founder and CEO Chris Lewis said McLintic felt he was ready for a new challenge and thanked the exec for his service. Lewis called Corsi a "great team leader" who understands clients needs for the future.

Lewis landed at No. 7 among the top 10 independent firms in the O'Dwyer's rankings with nearly $69M in revenue in 2015.
