Website Privacy Policy
Martha E. Wittenberg, MD, Inc. dba Thrive Health MD
Effective date: October 8, 2026
Martha E. Wittenberg, MD, Inc. dba Thrive Health MD ("we," "us," or "our") operates www.marthawittenbergmd.com and our online scheduling page at marthawittenbergmd.as.me (together, the "Site"). This Website Privacy Policy explains what information we collect when you visit or use the Site, how we use and share it, and the choices you have.
This Policy and Our Notice of Privacy Practices
Once you become a patient, the health information we create or receive in providing your care — medical records, lab results, treatment details, and billing information — is protected under the Health Insurance Portability and Accountability Act (HIPAA) and the California Confidentiality of Medical Information Act (CMIA). How we use and disclose that information is described in our Notice of Privacy Practices. If the two conflict, the Notice of Privacy Practices takes precedence. This policy covers information collected through the Site.
Please do not send medical information through the Site's contact or newsletter forms or by regular email. For medical questions, use our secure patient messaging or call (949) 464-8575. If you are experiencing a medical emergency, call 911.
