Hi, I'm Lisa Hendrickson-Jack
It's time to uplevel your women's health practice!
If you’re a woman's health professional and your clients aren't tracking their cycles — now is the perfect time to start!
Your menstrual cycle is not just about having babies! It's your fifth vital sign, and as such, it provides valuable insights when you pay attention.
You may have found me through one of my bestselling books, The Fifth Vital Sign, Real Food for Fertility (co-authored with Lily Nichols RDN), the Fertility Awareness Mastery Charting Workbook, or through my podcast, Fertility Friday.
If you've read any of my books or tuned into any of my podcast episodes, you already know that I'm obsessed with supporting women to establish a deeper connection to their menstrual cycles.
My work is known for being evidence-based, and with thousands of citations to dig into, my books (and podcasts) share an enormous amount of research in a conversational and approachable way.
I founded the Fertility Awareness Mastery Mentorship™ to empower women's health professionals to elevate their practices and support their clients through menstrual cycle and fertility awareness.
Since It's up to us to make the changes we want to see in the world, I invite you to join me in changing the face of women's healthcare.
