They helped build Morgan’s securities business in the 1990s, and both decamped from the firm last year after its purchase by Chase Manhattan. Now, after some individual travel and soul-searching, the pair are back together as co-founders of Logan Pass Partners, an investment and philanthropic venture with offices in the historic Graybar Building above Grand Central Station in midtown Manhattan. The firm - which takes its name from a Montana mountain pass that Rose and de Oliveira once traversed on a biking trip - will eventually become a vehicle for the duo to invest in companies that need capital as well as management expertise. Rose and de Oliveira are also teaching - jointly - a course titled “Leadership in Global Finance” at New York University’s Stern School of Business. “Ramon and I have been friends, partners and colleagues for the past 15 years, and we have a tremendous amount of fun working together,” says Rose. “We’re really trying to have an Act Two that’s markedly different from Act One.”
