I'm Lindsay "Loo." A founder, a chef and a wellness futurist.

Hi, I'm Lindsay O'Keefe (formerly O'Neill). For over 20 years I worked as an AI and machine-learning technologist. My career began in AdTech and Big Data, where I built platforms that automated billions of decisions in milliseconds.

Then I was hit by a car while pregnant with my third child. That moment launched years of chronic illness, medical gaslighting and tens of thousands of dollars spent on treatments that didn't work. My baby suffered while conventional medicine made things worse, not better.

"Root-cause functional medicine saved our lives. But finding what actually worked in this industry was brutal."

So I turned that same data-driven mindset inward, seeking diagnostics, biohacking tools and integrative solutions to restore my health. I trained in culinary medicine with Harvard T.H. Chan School of Public Health and the Culinary Institute of America, completed ACE Fitness' Wellness Coaching program, and launched Small Hinges Health in 2020.

That journey took me to the TEDx stage with The Data-Driven Journey to Optimal Health, and to Gaia, where I shared my story of resilience, science and health optimization.

In 2024 I launched Wellness Eternal to bring efficacy, trust and clarity to the crowded biohacking and longevity space. A year later we introduced The Wellness Index Report, the first platform of verified ratings and reviews for wellness solutions and providers. Every month, our Index Reports reach over 350 media outlets, including Business Insider, WSJ, MarketWatch and Yahoo! Finance.

At the heart of everything I do, whether through Small Hinges, Wellness Eternal or the Wellness Index Report Podcast, is one belief: you don't have to change everything to change everything. With the right data and connections, even the smallest action can unlock massive breakthroughs in health, longevity and human potential.
