Before founding Summer Health in 2022, she was the eighth employee at Hims & Hers, led business operations at Twitter as revenue scaled from $100M to $2B, and worked on more than $10B of IPOs at Barclays. She is an HBS MBA, a Sequoia Scout, and co-author of the startup business-development book 'Pitching & Closing.'
