She has performed at the Grand Ole Opry, four times at St. Peter's Basilica at The Vatican, four times at Carnegie Hall, for two U.S. presidents and Canadian Prime Ministers, and was the first violinist to perform at the Sistine Chapel at the Vatican since its first mass in 1483. She was awarded the Queen Elizabeth Diamond Jubilee Medal and Queen Elizabeth II Platinum Jubilee Medal for her contribution to the arts in Canada and is married to saxophonist and film composer Eli Bennett with whom she records and performs with their instrumental duo SaxAndViolin.

The Sistine Chapel is a chapel in the Apostolic Palace, the pope's official residence in Vatican City. Originally known as the Cappella Magna, it takes its name from Pope Sixtus IV, who had it built between 1473 and 1481. Since that time, it has served as a place of both religious and functionary papal activity. Today, it is the site of the papal conclave, the process by which a new pope is selected. The chapel's fame lies mainly in the frescoes that decorate its interior, most particularly the Sistine Chapel ceiling and The Last Judgment, both by Michelangelo.
