Our Mission

FLI MD is a longevity practice designed for women to live longer and healthier lives. We guide women to live intuitively supported by the most advanced scientific interventions and personalized data, by catching chronic disease before it begins, and establishing lasting, nourishing daily habits.  

I met Jessica Herrin in my early 30s and we became fast friends and confidants. As busy CEOs, overwhelmed mothers, and often exasperated wives, we faced a myriad of health challenges: neck surgery, energy depletion, chronic cortisol elevation, insomnia, and weight changes. For emotional support we thankfully had each other but for medical support we simply couldn’t find what we needed and didn’t even know what to ask for. 

Our  medical care was limited to brief consultations with prescriptions for Prozac and birth control pills. We and our peers felt lost and even angry at this alarming tolerance of women's suffering and a preference for masking symptoms rather than addressing underlying causes. It was as if the complexity and individuality of females led our doctors to concede: “your body’s a mystery, sorry”.

FLI MD is the medical practice we needed in our 30s, but never found.

Our passion to change women’s health intensified when we discovered the significant metabolic, cognitive, and physical declines that uniquely affect women as we enter perimenopause. The scale of neglect and the need for a more proactive approach became glaringly apparent. Just when we are coming into our highest form of wisdom, and deepest empathy, the medical system is letting us down. Yet, we discovered that advancing science can equip us with means to navigate our hormonal rhythms, unravel the enigmas of our bodies, and increase longevity and healthspan. 

The gap between this knowledge and integration into traditional medical practices is enormous and led us to join forces and seek out the highest skilled  women’s health experts globally, establishing the Female Longevity Institute (FLI MD). Our goal is to offer you access to personalized, longevity healthcare, empowering you to reclaim your vitality and transform the way you age.
