Born and raised in Brooklyn, NY with a BA in theatre from Hunter College and MBA from Hult International Business School. Vanessa has been fortunate to work with one of the biggest brands in the sports industry, the NFL, where she gained valuable experience in database, branding, events and program management.

"I all of a sudden found myself divorced from my ex-husband, the fibroids and the NFL. I knew something else was brewing around the corner that would replace so much experience". That something else was HULT. MBA students were challenged to build a business whose bottom had a triple effect. It was within the Hult Impact Challenge that BUPeriod was born."
