Katy (she/her) is a licensed acupuncturist who believes in empowering others to find their healthiest self through a holistic approach to healthcare. She is passionate about providing a safe empathetic space that allows for people of all different backgrounds and health histories to feel heard.
Katy specializes in working with complex chronic illness and autoimmune disease, digestive disorders, gender inclusive sexual and reproductive health care, women’s health, pain and injury, substance use disorder, supporting emotional well-being and mental health through trauma-informed care. Katy knows that trauma is often expressed somatically in the body and believes in the power of acupuncture, along with therapy, to help ease that expression. She has experience working with diverse populations and ages including BIPOC, LGBTQIA+, and persons with disabilities. Her approach uses gentle needling, palpation, herbal therapy and patient education along with her knowledge of Western medicine to provide collaborative care. She strongly supports the right to quality, inclusive healthcare.
Katy graduated with a Doctorate of Acupuncture and Chinese Medicine (DACM) from the American College of Traditional Chinese Medicine (ACTCM) of CIIS in San Francisco. She started her private practice in San Francisco at Ume Acupuncture learning Kiiko Matsumoto style acupuncture, a style that focuses on the root cause of disease. Katy started Root and Stem Integrative Chinese Medicine’s Sliding Scale acupuncture practice in Oakland, California doing private and community treatments. She has worked in private internships, at DeHaro auricular clinic, and Glide community acupuncture clinic. She studied Western herbalism with herbalist Matthew Woods, Erica Fargione and Cynthia Thomas. She is also a certified yoga instructor and loves to incorporate her knowledge of these systems into her practice.
Katy’s own discoveries of healing and learning through holistic modalities led her to the study of Chinese medicine. Katy loves yoga, biking, traveling with friends and family, learning French and exploring everything city life has to offer.
