Dr. Arielle (Sommer) Bilek is a general internist who practices in Torrance. She is board certified in internal medicine and sees both men and women of all ages above 18. As a primary care physician, she believes in the power of proactive preventative medicine, and enjoys counseling her patients on the science of how lifestyle factors (i.e., the foods we eat, our daily activities, and mental health) impact physical health. She aims to educate her patients in a way that is understandable and relevant, and that allows them to then make informed choices for their health that also fits into their lifestyle.

She then completed her internal medicine residency at McGaw Medical Center of Northwestern University, where she completed certificate trainings in women’s health and quality and safety improvement.
