He then took the obvious step of enrolling in a master’s program in Opera at Northwestern University. He sang professionally for several years before returning to Research and Development at Baxter Laboratories, then earned an MBA at Northwestern before going to work in the investment business with O’Connor & Associates and later for RCM Capital Management where he became a partner.
