Journalist. Community builder. Debut novelist.
I’m a journalist and community builder working at the intersection of women’s health, longevity, and science. I believe good communication is a form of care, and I bring that mindset, along with a decade of evidence-based storytelling and community strategy, to every project I take on.
My writing appears in National Geographic and Business Insider. I lead community and membership at Livelong Media, where I’ve helped build a space for 70,000+ women navigating health and longevity on their own terms. And my debut sci-fi novel, Home Planet, is out now from Atmosphere Press.
I’m based in Denver, CO, where I spend my days herding cats, children, and words on the page. Not necessarily in that order.
✍️ Journalist & Writer
Reported features and content strategy at the intersection of women’s health, longevity, and science. Bylines include National Geographic, Business Insider, and Her Agenda, among others. I translate complex research into stories that actually land, and help health and wellness brands find their editorial voice.
🌍 Community Builder
VP of Community & Membership at Livelong Media, where I help build a space for 70,000+ women navigating health and longevity on their own terms. I’ve also led community at Yelp and The Mom Project, and I know that a healthy community isn’t an accident. It’s built with intention.
🪐 Debut Novelist
My first novel, Home Planet, follows astronaut Bryn on a solo mission to find humanity’s last hope, carrying a secret that could cost her everything. Propulsive, intimate, and full of wonder. Out now.
MA Creative Writing, University of Denver · BS Journalism, University of Colorado Boulder
For brands & editors
I help health and longevity brands turn complex science into content people actually read (and trust): reported articles, newsletters, search-smart long-form, and community strategy. I built Yelp’s community program as one of its first 100 employees, and I’ve since worked with teams like Livelong Media, The Mom Project, and Trusted Health.
Want the details? My services, process, and specialties are all in one place.
Why I focus on women’s health
It took me two years to figure out what was happening with my own body. Two years of symptoms, dead ends, and doctors who weren’t asking the right questions, until I realized the research they were drawing from often wasn’t designed with women’s physiology in mind at all.
So I started digging. Into perimenopause. Into how hormonal fluctuations change everything from how we fast to how we sweat to how we sleep. Into why so much longevity research defaults to male biology. Into the gap between what women are living and what the science actually says about us.
That’s what drives a lot of I write these days and my work with the Livelong Women’s community we’re building. I believe good communication is a form of care, and I bring that mindset, along with evidence-based rigor and emotional intelligence, to every story I shape and every community I build.
I believe that women deserve a health conversation built for them. One that takes our biology seriously and gives us somewhere to gather with people asking the same questions we are.
Out Now
