Based in Munich, La Pierre will be responsible for the acquisitions, asset management and fund management teams across all of continental Europe.
He will also be joining the European management board, the real estate investment manager said.
La Pierre previously worked as the co-chief investment officer for the Luxembourg-based property investment manager Corestate.
Simon Marrison, the CEO of Europe at LaSalle, said: “I am delighted with the appointment of Philip to our continental business; his experience and knowledge of European real estate markets will reinforce our position in on the Continent, particularly in Germany.
“This is a key market for international investors, and Philipp’s appointment will reinforce our role in the domestic market and build on our existing presence in the country.”
