TeraPractice is a new approach to primary care that provides personalized care wherever you are. Get in touch with your health team through on-the-go messaging, video visits and same-day appointments. Whether you want to stay healthy, manage a chronic condition or improve your mood, Tera provides easy access to primary care services. We see health as a journey, and we offer support along the way.

Primary care, in your pocket

A small team that knows you — and your life

The Tera team includes a primary care doctor, nurse and health coach who get to know you beyond your medical chart. Whether you prefer light touch or in-depth support, your team will consider your needs and create a health plan to match.

Mobile messaging and video visits

With our app you can send messages, video chat with your care team and schedule in-person appointments when needed. Our virtual-first model means healthcare fits into your life – not the other way around.

More access to care, less cost for you

Tera provides convenient care at no extra cost. Video visits have a standard copay, while calls and email messages are free of charge. Plus, Tera is a part of the Sutter Health network, which means you have access to a wide range of specialists, when you need it.

Frequently Asked Questions

Tera is a medical practice led by Yumi DiAngi Taylor, M.D., which provides a flexible alternative to primary care. The care team includes Dr. Yumi, plus a health coach and a nurse. You can expect the same services you receive from your PAMF primary care provider, plus additional benefits like flexible scheduling, personalized coaching, video visits and on-the-go messaging. This access can reduce the need for in-person appointments because you have a care team to answer questions and treat symptoms as they arise.

Plus, the Tera care team acts as a single point of contact to address your questions, resolve health problems, review lab results and help you manage medications. This team helps you schedule appointments with specialists and works closely with those doctors to make sure your needs are met. We also communicate with the people involved in your healthcare, including family members, caregivers or other providers you give us permission to share with. With Tera, you have flexible access to your care team through Sutter’s My Health Online (MHO) app. MHO can be used to send private messages, access digital tools and conduct video visits.

Additionally, our virtual-first model means that we can provide longer appointments when you need it, and quick ones when you don't. Many patient needs can be met through phone, email, or video visits, and in-person appointments can be easily scheduled when needed.
If you have an issue that requires in-person care, the team will connect you with Dr. Yumi or an appropriate PAMF provider. We’ll set up the appointment for you to ensure seamless coordination and follow-up.
Please fill out the Contact Us form. If you are eligible for Tera, the team will follow up via phone or email. Once you enroll in Tera, we will send you an intake survey, followed by a Doctor Meet & Greet video call. This is a chance for us to get to know you and understand your health needs.
We believe that good healthcare should be accessible to everyone, and we built a model to match. This expanded access is provided at no additional cost. Your Doctor Meet and Greet video visit does not have a co-pay. Any visits that can be resolved via email or phone call have no co-pay. Depending on your health plan, there may be a co-pay for video visits, just as there are with office visits.

For additional questions about copay and insurance reimbursement, your insurance company is usually the most knowledgeable. Their con-tact information is printed on your insurance card.
Please send questions or appointment inquiries to Dr. Yumi via My Health Online messaging. A member of your care team will follow up shortly with a My Health Online message or a phone call.
A cell phone or laptop is all you need to access video appointments and My Health Online. Through the My Health Online app, you can email your care team, see lab results, request prescription refills and make appointments. Much of our communication happens via the My Health Online app, so we ask that patients consider their comfort with mobile applications when considering becoming a patient.
As much as they can, our care team will troubleshoot initial technical issues with telemedicine, My Health Online and other digital tools. For specific questions about My Health Online, you may also contact our support team any time.

Thanks for letting us be a part of your health journey.
