A native of rural Southern Illinois, Brad began studying music as a young child.  Through elementary and secondary education, instrumental music was very important to all aspects of his education.  He attended Southern Illinois University Carbondale as a Music Education & Music Theory / Composition student, where he excelled in instrumental pedagogy and marching arts techniques.  Brad graduated in 2002 with a Bachelor of Music degree in Music Education, at which time he served as Director of Bands for Vandalia Community High School before moving to Colorado in 2004.  Since arriving in Colorado, Brad diversified his background by working with multiple corporations as an educational consultant and information management specialist before returning to performing and teaching music full-time.

I studied flute performance seriously through college, however the academic rigors of medical school left no time for practice.  I was unwilling to perform without practicing regularly, and did not play/perform for 30 years.  I found my way back to music in 2008 and have been studying privately since.  I have attended the Baltimore Symphony Orchestra Academy yearly since 2011, and Interlochen Adult Chamber Music Camp since 2010.  After substituting on piccolo for one season with the ASO, I auditioned and was awarded the piccolo chair in 2015.  After a 35 year career in obstetrics and gynecology, being recognized as a “top doc” in 5280 magazine for 6 years, and 24 years at University of Colorado, I retired in 2017.  Currently, I am studying music theory at Metropolitan State University Denver.

Growing up in Jefferson County, CO, I had the opportunity to take piano and clarinet lessons throughout my childhood, and participated in both the Alameda High School and CU Marching Bands. Although I have no real musical talent, I love supporting the Aurora Symphony Orchestra professionally as their Board Treasurer, Fundraising Chair, and Event Coordinator. 

I began playing the cello in third grade, when it was offered as a ‘before school’ program through Aurora Public Schools.  My love and dedication to such a wondrous and precious instrument carried through for decades.  I credit my music teachers, specifically Mr. and Mrs. Humphrey and the Strolling Strings for incredible opportunities and experiences.  As a board member of the Aurora Symphony Orchestra, I am proud to serve my community and share my love for music, instruments and education.
