Rebecca Donatelli, ABR, SRS, 28, is a math nerd and a former competitive fencer who loves a challenge. At John Carroll University outside Cleveland, she studied to become a math teacher, but took a job as an account manager for an insurance company after graduation. Unfulfilled, Donatelli took her mom’s advice and started a real estate career that benefits from her love of numbers and provides an outlet for her creativity. Using Instagram to share daily stories about her life and engage with clients and other agents catapulted her to “influencer” status in a little over two years, with more than 13,200 followers. Last year, Instagram connections led to $2 million in sales. Now she’s on the speaker’s circuit talking about building a social media presence. “Helping others build their business makes me incredibly happy,” she says.
