Bach; Spanish works by Jose Lidon and Bernardo Pasquini; and numerous early English works by composers such as Jeremiah Clarke, William Boyce, Thomas Thorley, Samuel Wesley, and Matthew Camidge. In addition she performs twentieth century works of her own as well those of Jehan Alain, Anton Heiller, John Leavitt, Paul Manz, and Austin Lovelace. Her own compositions make up an increasing portion of her worship and concert repertoire.

In 2010 Bonnie performed with her husband in concerts throughout Europe, performing works by German, Spanish, and French composers plus works of her own. The most unique instrument they played was the 1900 Rieger Testverek organ in the church of her great-grandparents in Majerka, Slovakia. If anyone knows about this organ or the organ builder, she would love to hear from you.

They also performed in Berlin and Neuhofen in Germany and in Weyer, France.
