Founder & General Manager

Jess Graham

As a member of LGBTQ+ community, the youngest of four daughters, and the graduate of a women's college, Jess has always been conscious of bias — in health, education, research, the workplace and in everyday life. So, after a successful 15+ year career in Financial Services, Jess pivoted to work she felt could have a more meaningful positive impact on society, which led her to senior leadership roles in human genomics (at Helix), data and privacy (at Facebook) and culture and technology (at Instagram). Needless to say, she's extremely proud to be the General Manager of Phenology, (which is backed by DSM Human Nutrition), a company that is committed to women's health and wellbeing. Jess lives in Brooklyn with her wife, Kelly, and their goofy great dane, Philo, and is an active mentor in the LGBTQ+ and BIPOC communities.
