Justin Biddle, MSN, JD, NP

Before joining Marin Cancer Care, Justin Biddle, NP, worked as a registered nurse in palliative care, where he supported patients and families facing serious illness. That experience shaped his approach to oncology, emphasizing compassionate communication, symptom management, and patient-centered care.

Justin completed his nurse practitioner training at UCSF, followed by the UCSF Cancer Services Advanced Practice Provider Fellowship, where he gained experience across outpatient oncology, hematology, infusion care, inpatient hematology, and cancer survivorship.

At MCC, Justin partners with patients and families throughout diagnosis and treatment, focusing on evidence-based care that reflects each person’s goals, values, and needs. He believes the best cancer care treats both the disease and the individual living with it. A native of Marin County who still calls Marin home, Justin feels grateful to practice in the community where he grew up. Outside of work, he enjoys trail running, mountain biking, skiing, cooking, and spending time outdoors.
