Marina started dance at 4, added violin and piano at age 7, and then went on to study opera and violin at the prestigious Manhattan School of Music. She pursued a career as a singer/dancer/actress, supplementing her income by teaching aerobics at Body Design By Gilda. She met her partner for life, recording engineer Roy Kamen, at The Music House, a major music/audio production studio in NYC. Soon the two launched their own studio, Kamen Entertainment Group, Inc., which opened in 1987.
