Thomas Cassara and David Rosenblum were named managing directors at P-Solve.
In the new positions, Messrs. Cassara and Rosenblum will open a New York office for P-Solve, the London-based investment consultant's fifth office in the U.S.
They will work directly as retirement plan consultants with existing and new retirement plan clients and also will oversee and mentor new actuarial and investment consultants hired by P-Solve to staff the office, said Ryan McGlothlin, global head of strategic relationships, in an email. The pair also will be responsible for business development.
P-Solve will be renamed River and Mercantile Solutions on July 2.
Messrs. Cassara and Rosenblum both were senior partners at Mercer, based in the New York office. Mr. Cassara was an investment consultant and Mr. Rosenblum was a consulting actuary.
Jordan Iseral, a Mercer spokeswoman, said in an email that other Mercer employees had assumed the duties of the departed pair.
P-Solve managed a total of $46 billion in outsourced and multiasset investment solutions programs as of March 31.
