The Trillium Model

A medical home, not a
revolving door.

At Trillium, we intentionally keep our panels small. That means more time with each patient, careful consideration of all contributing factors, and real continuity of care — getting to know patients and their families over time.

The result is comprehensive, personalized primary care that the traditional insurance model simply doesn't allow. No rushed visits. No insurance company deciding what care you receive. Just two experienced physicians who are fully invested in your health.

Unhurried appointments built around what you actually need


A physician who knows your history — no repeating yourself


Urgent care handled in-clinic, by your own doctor


Transparent, predictable pricing — no surprise bills


Two physicians who cover for each other seamlessly

Why Concierge Medicine

Medicine the way it was always meant to be.

Concierge medicine at Trillium isn't about exclusivity — it's about restoring a more personal, relationship-centered approach to care. By keeping our panels intentionally small, we can offer something the traditional model has made nearly impossible: a physician who truly knows you.

"Profit-driven insurance pressures have made it difficult to provide the kind of care I would want for myself and my family. The Trillium model allows me the freedom to practice medicine the way I think it should be done — with time, thoughtfulness, and care."

For patients who value continuity, access, and a physician who is genuinely invested in their long-term health, concierge medicine offers something rare: confidence in your care, and peace of mind over time.

You still need health insurance

We strongly recommend maintaining health insurance for services outside our practice — specialist care, hospital stays, imaging, and emergency services. Your Trillium membership covers your primary care relationship; insurance covers everything else.


We don't bill your insurance

Trillium operates outside the insurance billing system. This is what allows us to give you the time and access you deserve. You may be able to submit visit-related fees to your HSA or FSA — we're happy to provide documentation.


We can refer you to specialists

We coordinate referrals to specialists in your insurance network, and they bill your insurance directly. After decades of practicing in this community, our physicians have personal relationships with many of the area's top specialists.


Concierge care is not DPC

Direct Primary Care (DPC) and concierge medicine share some similarities but differ in scope, pricing, and model. We're happy to walk you through the differences at your meet and greet.

Find the right fit
for your care.

Choosing a primary care physician is personal. We invite you to schedule a complimentary meet and greet with Dr. Casey or Dr. Nelson — a free, no-pressure conversation to see if Trillium is the right home for you and your family.
