Welcome Friends and Colleagues,

Thank you for visiting my web site. Here, I have gathered together in one place a summary of my work in choral music.

I hope that you will find information that is helpful and inspirational on these pages. Read about the Mansfield University choral ensembles and listen to excerpts from some of our recordings.

Perhaps you will find a concert that you can attend some day soon.

I also enjoy working as a guest conductor and clinician. By visiting the repertoire or workshop links, you can view the variety of topics and music that I might bring to your festival or conference.

Please feel free to contact me if you have additional questions!
