Hepatitis C Treatment
We provide comprehensive hepatitis C treatment for patients regardless of transmission history. Our clinic offers free confidential testing, medical consultations, and tailored treatment plans. With expertise in managing complex cases including co-infections and cirrhosis, our medical team delivers care that addresses both viral hepatitis and associated psychosocial needs.
Addiction Medicine
Our specialized addiction medicine services address substance abuse histories alongside hepatitis C treatment. We offer buprenorphine therapy, methadone maintenance support, and harm reduction strategies. Our approach integrates behavioral health services with medical treatment to improve outcomes for patients with long-term substance use disorders and co-occurring infections.
Peer Education Programs
We deliver peer-led education through outreach programs and weekly support groups. Our peer educators provide hepatitis C awareness training, testing linkage, and treatment navigation. With lived experience in addiction recovery and healthcare advocacy, our educators help patients understand their diagnosis and access appropriate care resources.
Medical Research Studies
We conduct innovative research on hepatitis C treatment efficacy and neuropsychiatric effects of interferon therapy. Our studies focus on underserved populations including transplant-ineligible patients and those undergoing medication-assisted treatment. Participation provides access to cutting-edge therapies while advancing medical understanding of viral hepatitis management.
Preceptorship Training
Our preceptorship program trains future healthcare providers through hands-on experience with marginalized populations. Medical students from UCSF and UC Berkeley learn patient-centered care approaches for underserved communities. This training helps reshape medical education by emphasizing compassionate care for patients traditionally excluded from healthcare systems.

Apr 11, 2022 Report
I got treated for my Hep C through Kaiser, but my education and support came from OASIS Clinic. Such an incredible place with incredible people. Dr. Sylvestry knows her stuff, Harvard educated, and certainly isn't just in it for the money.
