Your Health Deserves a Familiar Team

At Discover Health Marin, a conversation about your health has room for the details. Our internal medicine physicians learn about your medical history and the goals that matter to you, then work with you on a plan.
We care for adults and seniors through preventive visits and ongoing health concerns. When treatment involves other doctors, our team helps coordinate care so you have support as decisions develop.

Time to Understand What Comes Next

Your appointment should leave room to talk through recommendations, including the questions that come up along the way.

Our concierge model gives you longer visits and an ongoing relationship with your physician. Together, you can address a new concern while keeping prevention in view. Direct contact between appointments lets you follow up when something needs another conversation.

Stay Connected to Your Care

Our concierge practices provide the benefits of extended visits, 24/7 communication, and other benefits like text messaging with your physician—all supported by a predictable monthly fee or annual retainer.

Contact Your Physician

Health questions do not follow office hours. Members have 24/7 access to physician support, with same- or next-day appointments available when you need a visit.

Make a Plan for Prevention

Bring your long-term health into the conversation. Your physician helps you build sustainable habits around nutrition and activity, with preventive planning that reflects your medical history and personal goals.

Build on Each Visit

Care becomes more personal as your doctor gets to know you. That familiarity helps guide ongoing conversations, keeping your changing needs and priorities part of the plan.

Navigate Care With Support

Managing a chronic condition can involve several physicians. Our team helps coordinate with your specialists and, with your permission, include loved ones in conversations about your care.

It’s care that feels worth it. My previous doctor barely remembered my name. At Discover Health, I’m not just a number. I’m a person with a story—and a plan.

I’d heard people talk about concierge medicine before, but I didn’t realize how different it could feel. My doctor knows my name, my history, and helps me stay ahead of issues before they become problems.

Dr. Castelli is very patient, reassuring and meticulous. We really enjoyed interacting with him. He answered all our questions in detail and put us at ease regarding the well-being of our son. The support staff is excellent too. Highly recommended.

Vinima Aggarwal

Satisfied Member

We’ve been with Discover Health for 10+ years and can’t recommend it highly enough. The support staff are great, as are the doctors: responsive, knowledgeable, and good listeners. To name just the ones we’ve been with recently: Dr. Jon-Michael Castelli, Dr. Oded Herbsman, and Dr. Desmond Wilson — all awesome!

Stephen Fraga

Satisfied Member

Always a great experience with Dr. Herbsman! He always makes my kids (and me) feel comfortable. He’s very informative, takes time to answer all questions, and is always around in case of emergencies. Very lucky to have found Discover Health.
