15. Whitney Holtzman, CEO & Founder, Social Victories
After holding impressive roles as a reporter for ESPNW, a Social Media Producer for the MLB, and working as an Account Manager for VaynerMedia, she set out to carve her own path. Soon after making that leap, she booked her first client and created "Social Victories". Almost 3 years in, she's helped multiple professional athletes create a second career for themselves, and she's even written a book about her journey.
