Lisa Hendrickson-Jack

Lisa Hendrickson-Jack is a certified Fertility Awareness Educator and Holistic Reproductive Health Practitioner who trains women’s health practitioners to use their menstrual cycle as a vital sign in their practices. She is the founder of the Fertility Awareness Mastery MentorshipTM program.

She is the author of three bestselling books: Real Food For Fertility (co-authored with Lily Nichols), The Fifth Vital Sign, and the Fertility Awareness Mastery Charting Workbook. Lisa works tirelessly to debunk the myth that regular ovulation is only important when you want children by recognizing the menstrual cycle as a vital sign.

Drawing heavily from the current scientific literature, Lisa presents an evidence-based approach to help women connect to their fifth vital sign by uncovering the connection between the menstrual cycle, fertility, and overall health — something our education systems have consistently failed to do.

With well over 4 million downloads, her podcast, Fertility Friday, is the #1 source for information about fertility awareness and menstrual cycle health. When she’s not researching, writing, and mentoring women's health professionals, you’ll find her spending time with her husband, her two sons, and her baby girl.
