I earned my B.A. Degree (Cum Laude) from Florida Atlantic University in 1999. In 2003, I graduated from Florida Atlantic University with my M.B.A. (AACSB Accredited) with honors. In 2010, I graduated from the Shepard Broad School of Law at Nova Southeastern University with my J.D., with Dean’s List Honors.
