Lauren Pallis, MD


Lauren Pallis joined Temescal Creek in 2023 after working as a hospitalist and then as a primary care physician. Through her prior professional experiences in various healthcare systems, Lauren learned that she wanted a smaller and more personalized setting to practice medicine, in order to be able to provide thoughtful and thorough care. After meeting Drs. Franchett and Zimmerman and learning about the ethos of their practice, she made the easy decision to join Temescal Creek Medicine.


Lauren Pallis was born and raised in the Bay Area. She attended the University of California, Berkeley for college and left the Bay Area to attend medical school at Jefferson Medical College in Philadelphia, PA. She returned home to complete her family medicine residency at Contra Costa Family Medicine Residency. After residency, she spent a year in Seattle, WA at Swedish First Hill completing a fellowship in hospital medicine.


As a provider, Lauren aims to meet people where they are and help them set realistic and achievable health care goals. She believes that one’s physical health is strongly tied to their mental and emotional health, and strives to understand all three aspects of patients’ lives when developing a treatment plan. Within family medicine, Lauren is particularly interested in women’s health, mental health, exercise and nutrition, as well as managing chronic conditions. 


Outside of medicine, Lauren enjoys cooking, being in nature, seeing live music, and spending time with friends and family.
