Macy Williams
WFHC Coordinator

My name is Macy, and I am from Livermore, California in the East Bay Area. I recently graduated from UCSB with a BS in Pharmacology with a special interest in developmental biology. Post graduation, I have been working as a medical scribe for an orthopedic surgeon while preparing to apply to medical school. I have loved having the opportunity to form long-term relationships with patients while learning from professionals in the healthcare industry.Volunteering in my community has always been a passion of mine, so I was very excited to find out about Doctors Without Walls (DWW) while in my gap year after graduation. I began volunteering in the Women’s clinic as a scribe before also crossing over into our Wednesday morning clinics at the NNC Rescue Mission.My involvement with DWW has allowed me to establish deep and meaningful connections with other volunteers, clinicians, and most importantly our patients who make up a small, but important part of our Santa Barbara community. It is always a great pleasure to encounter familiar faces at the clinic each week, but I am equally enthusiastic about getting to know and assisting new individuals and will especially always try to recruit new ladies to come hangout on Fridays at our Women’s clinic.

The Women’s Clinic mission, to provide holistic care, strongly aligns with my belief that access to basic amenities such as clean clothes, hygiene products, water, food, and resources for mental health is just as vital as medical care, and I look forward to continuing this mission as the Women’s Clinic Coordinator. I am passionate about women’s health and aspire to be an OB/GYN one day to continue serving the women in my community, and I hope to continue to work with underserved populations wherever I end up in my career.

In my free time, I enjoy experimenting with new recipes, spending time on the lake, visiting with my dog Jax, and drinking lots of coffee 🙂
