Stephen Ramsthaler is listed as a managing director based in the Blackstone secondaries unit’s New York office, according to its website. It is understood he joined in August after retiring from GCM Grosvenor.
A spokeswoman for Blackstone confirmed his appointment.
Prior to joining Chicago-based GCM Grosvenor, Ramsthaler was a managing director in Credit Suisse’s asset management division, where he was responsible for overseeing various operations including Strategic Partners, prior to its purchase by Blackstone.
Grosvenor’s latest fund is its $700 million GCM Grosvenor Secondary Opportunities Fund II, which it closed in February last year. Its debut 2015-vintage secondaries fund collected $58.2 million, according to Secondaries Investor data.
Strategic Partners is investing its $11.1 billion Fund VIII, on which it held a final close in July.
