Sara Koenig, PNP

Pediatric Nurse Practitioner she/her
Larkspur Office: Mon, ThuNovato Office: Wed

Sara is a life-long Bay Area resident. She was born in San Francisco and raised in Mill Valley, spending her childhood in the shadow of Mount Tam. College was also close by, down the coast to UC Santa Cruz, to earn a degree in Sociology.

Sara’s nursing path started years ago when a close friend passed away from cancer. She realized through that experience that she wanted to work in healthcare. She got a job working at UCSF as a clinical trials coordinator in Pediatric Oncology. It was there that Sara met two wonderful nurse practitioners, who, in her eyes, had mastered the art of blending medical knowledge with a compassionate human touch. They soon became her mentors, and she started going to night school to complete the prerequisites for nursing school. During her years at UCSF, Sara also spent time volunteering in the Child Life Department helping chronically and acutely ill children manage their illnesses through play therapy.

Sara earned her RN and MSN from Yale School of Nursing. After graduating in 2008, the strong pull of friends and family enticed her back to the Bay Area. She has worked as a pediatric nurse practitioner in the East Bay, Sonoma, and Marin since joining Tamalpais Pediatrics in 2012. Sara lives in San Rafael with her husband and two teenage sons. When not working, Sara enjoys hiking with her husky, doing yoga, traveling, and spending time with friends and family.
