ABOUT YOUR NURSE PRACTITIONER

Jennifer Nathanson, NP

Meet Jennifer, a board-certified nurse practitioner, functional nutritionist, and practitioner of functional and integrative medicine. With over 23 years in healthcare, Jennifer blends modern science with natural approaches to empower women in transforming their health from within.

Her journey, coupled with professional experience, revealed a gap in conventional healthcare—a lack of care and healing. Passionate about providing a better client experience, Jennifer adopts a gentle, collaborative, and client-centered approach, focusing on sustainable solutions. She specializes in functional and integrative health while embracing the therapeutic potential of plants and herbs.

Jennifer holds a Master of Science in Nursing from the University of California, San Francisco (UCSF). She has completed training in Women’s Functional & Integrative Medicine with Dr. Aviva Romm and is an Applied Functional Medicine Certified practitioner. She is also
certified as a Functional Nutrition & Lifestyle Practitioner (FNLP) through the Functional Nutrition Alliance.

Dr. Hillary’s heart-felt approach to holistic health care has forever changed how I think about health and healing for my family. Her education and hands-on experience in women’s health, which spans treatment in fertility issues to managing menopause and beyond, has made her the perfect primary doctor for our family. The fact that she is an absolutely amazing human being on top of it has made us truly thankful that she came into our lives!


We are forever grateful to Hillary for her guidance during some very difficult times in our family’s health journey. She has helped us navigate and find solutions to every challenge that has come our way- from raising toddlers, managing puberty, and the sensitive issues our twin daughters are currently facing as teens. Because of her wonderful qualities, Dr. Hillary has become a completely trusted and much loved member of our family.

Working with Dr. Hillary has been the smartest investment I've made in my health, ever. And, I've tried a lot of doctors and a lot of approaches! Hillary is kind, intelligent and offers a practical and collaborative approach to health care - all in the name of getting to the root cause of things. I'm super excited to do the Fall Detox, too - her knowledge of food as medicine is impeccable! I've spent my 40's quite miserable and it doesn't have to be this way - do yourself a favor, and make an appointment to see her. You will be so glad you did!

Working with Dr. Hillary dramatically changed my perspective on health-fullness. She is both a skilled physician and a wise counselor, combining many medical modalities with deep compassion to build trust, treat, and educate. Dr. Hillary treats my whole person, looking beyond single medical tests to instead, combinations of factors that explain what's happening in my body. She has been especially supportive, as a doctor and teacher, through multiple stages of womanhood -- from fertility, to childbearing and postpartum, to perimenopause, and planning for longevity. The combination of her treatment protocols and many creative and informative programs have taught me so much about how to create and sustain health for myself and my entire family -- everything from the food we eat, to our approach to medicines, to the lifestyle choices we make. Dr. Hillary is not just my doctor, but my partner in health.
