About Nest

Our Story

Nest Acupuncture was founded in 2006 by Sara Stieg, with the vision of creating a nurturing space where women feel deeply supported throughout every stage of their reproductive journey. With advanced training in reproductive medicine, functional nutrition, and Chinese medicine, Sara built Nest to be a sanctuary for personalized, compassionate care.

While we are well known for our expertise in fertility and pregnancy care, we support women through all phases of lifeβ€”from the first menstrual cycle through menopause and beyond. Whether you’re navigating hormone shifts as a teen, preparing for pregnancy, recovering postpartum, or seeking balance during perimenopause, we’re here to walk with you every step of the way.

Our talented team of practitioners shares a deep commitment to attentive, holistic care. We take the time to truly get to know our patients, tune into their unique needs, and treat them with a gentle hand and a kind heart. It’s our joy to help you heal, thrive, and feel at home in your body.

Sara Stieg

Founder | Acupuncturist

  • Sara Stieg, M.S., L.Ac., FABORM, is a licensed acupuncturist who specializes in women’s health, fertility, and pregnancy support. From the start of her practice, her focus has been on reproductive medicine. She is guided by the principles of integrative medicine, often collaborating with doctors and other health care practitioners to maintain continuity of care.

    Passionate about helping couples achieve their goal of becoming parents, it brings her great joy to be part of this personal and meaningful journey. The foundation of her nurturing and supportive approach is a commitment to keeping her patients informed so they can be active participants in achieving optimal health.

    Sara was first introduced to acupuncture as a student at the UC Santa Cruz where she earned a Bachelors degree in psychology. After experiencing great success using Chinese medicine to treat her own health issues, she continued her graduate studies in Traditional Chinese Medicine so that she could share its benefits with others.

    Sara completed a Masters of Science degree from the American College of Traditional Chinese Medicine in San Francisco. She has also received advanced postgraduate training in the fields of gynecology, reproductive medicine, pregnancy and pediatric acupuncture.

    While she is no longer associated with PFC, in 2007 Sara co-founded the Acupuncture Program at Pacific Fertility Center (PFC), a leading Assisted Reproductive Therapy Clinic in San Francisco. The focus of the Acupuncture program was to provide onsite treatments to women on the day of their embryo transfer and support them before and after their cycle. Sara continues to provide fertility acupuncture to patients that are undergoing assisted reproductive therapies at clinics in the San Francisco Bay area.

    Sara has been a Fellow of the American Board of Oriental Reproductive Medicine (FABORM) since 2009. ABORM certification demonstrates the highest competency and advanced knowledge in the field of both Western and Oriental Reproductive Medicine.
