Jenn has both a business and technical background, and has worked for multiple Fortune companies as well as startups throughout her career, including companies centered around technology, software, banking, stock brokerage, transportation, and industrial automation. She has frequently been called upon to work with executives and corporate partners, and lead large global programs that require both strategic thought and attention to detail. Jenn has expertise in consulting, mediating, data analytics, employee engagement, customer experience, change management, Lean Six Sigma, and building cross-functional teams.
Jenn became aware of the benefits of bats over 20 years ago when she moved to a ranch and found the need for natural bug control. Being a conservationist at heart, as well as a proponent of managing property through organic measures, she discovered that bats were the perfect solution. This discovery resulted in two custom-made bat houses being built and installed on the ranch, and are now home to over 600 Mexican Freetail bats. The houses became maternity wards due to their location along the bats’ yearly migration path, were quickly inhabited, and are still in use to this day. This was the start of Jenn’s love for bats and her understanding of the critical need to protect this important and unique mammal and its habitats.
Jenn holds an MBA from UMass Amherst, and a Bachelors in Computer Science from Loyola University New Orleans. She is thrilled to leverage her expertise to support Bat Conservation International’s mission to “conserve the world's bats and their ecosystems to ensure a healthy planet.”
