She currently serves as concertmaster of the Chattanooga Symphony & Opera and began developing her leadership skills at the renowned Peabody Institute of the Johns Hopkins University with former Baltimore Symphony concertmaster Herbert Greenberg. In recent seasons she has enjoyed serving as guest concertmaster for the Columbus Symphony (OH), Baltimore Chamber Orchestra, and a one year appointment as interim concertmaster for Orchestra Iowa.
As an in-demand performer, Holly maintains a very busy schedule serving as traveling concertmaster for the Emmy Award winner George Daugherty’s Bugs Bunny at the Symphony program and performing with Grammy award winning Nashville Symphony and Milwaukee Symphony.
She spends her summers at the celebrated Grand Teton Music Festival where in addition to performing in the violin section and assistant principal second, Holly volunteers as an active chamber musician. In the summer of 2011, she performed Pulitzer Prize winning composer Jennifer Higdon’s Piano Trio under Ms. Higdon’s direct supervision. Following the performance, Higdon said, "Working with Holly Mulcahy was fantastic. She’s a superb musician and a great colleague. I always think my Piano Trio is a great test for violinists, because it has such wildly varying moods: long and lyrical lines, delicately played, and then racing and driving rhythms, moving at top speeds with intensity. Holly nailed it all splendidly. I would work with her again any chance I could. She was wonderful."
