Over the years she has performed in bands, community orchestras, and ensembles and continues to play the flute today as a member of the Jackson Hole Community Band.  One of the highlights of her first year living in Jackson was playing patriotic songs on the back of a flatbed truck in the town Fourth of July parade. 


Lesli holds an MBA in Marketing from Columbia Business School and a BA in Mathematics from Wellesley College. She worked as a marketing brand manager at Kraft General Foods and Del Monte and as a commercial banker at Marine Midland Bank.

Lesli lives in Jackson with her blues guitarist husband and has two musically-talented adult children. As a new member of the board, Lesli hopes to contribute her marketing and business background and her experience as both a music learner and as a parent of musicians to expand music education for students in the Jackson community.
