John Sant'Ambrogio has enjoyed an illustrious career as a cellist in top orchestras, chamber music ensembles and as a pedagogue for over five decades.  Appointed Principal Cello of the Saint Louis Symphony Orchesta in 1968 after being a member of the Boston Symphony Orchestra for nine years, Mr. Sant-Ambrogio has served as Principal Cello of such orchestras as the Casals Festival (Puerto Rico), Grand Teton Music Festival (WY), Lancaster Festival (OH) and the Seventh Army Symphony (Europe).  In 1987, he founded and was the first Artistic Director of Strings in the Mountains in Steamboat Springs, Colorado.  His discography includes chamber music and orchestral recordings on the TELARC, RCA, IMG and VOX labels.  Mr. Sant'Ambrogio studied with Leonard Rose, Paul Olevsky and Diran Alexanian and has passed on these pedagogies while on the faculties of Washington University, the St. Louis Conservatory and Boston University .  His students have won jobs in major symphony orchestras, including the Boston Symphony Orchestra, the Chicago Symphony and the Saint Louis Symphony Orchestra.  Retiring from the SLSO in 2005, he moved to Steamboat Springs to pursue his love of skiing, hiking, cycling and photography.  Still a very active chamber musician and teacher, he founded the Generations Piano Trio in 2005 with violinist Dmitri Pogorelov and pianist Judith Lynn Stillman.  Mr. Sant'Ambrogio continues to perform throughout the country with his trio and, to his delight, with his daughters Stephanie, violinist, and Sara, cellist.
