The Practice
A medical home built on relationships, not transactions.
At Trillium, we deliberately see fewer patients so we can do more for each one. That means longer appointments, next-day access, and a physician who knows your history, your family, and your goals — not just your chart.
Drs. Casey and Nelson have spent decades caring for families in this community. They didn't walk away from that — they built something better.

WHY CONCIERGE CARE
You've felt the difference.
Here's why it exists.
Most physicians want to practice medicine this way. The traditional insurance model doesn't let them. Concierge medicine removes that barrier — for everyone.
Sound familiar? Here's what changes.
Waiting hours for an appointment
Same or next business day appointments.
When you're sick, injured, or worried, you shouldn't have to wait. Trillium members get in when they need to — not when the schedule allows.
Rushed 10-minute appointments
Longer visits. No clock-watching.
Appointments are built around what you actually need — not what an insurance schedule allows. Dr. Casey and Dr. Nelson take the time to listen, think, and explain.
Seeing a different doctor every visit
One doctor. One relationship. Over years.
Your doctor knows your history, your family, your goals — without you having to repeat yourself every time. That continuity changes everything about the care you receive.
Waiting hours for an appointment
Your care. Not your insurance company's.
At Trillium, clinical decisions are made by your physician — not by what an insurer will approve. You get the care that's actually right for you.
Fragmented care between urgent care and specialists
Coordinated, continuous, connected care.
Dr. Casey and Dr. Nelson handle urgent issues in-clinic, coordinate with specialists they know personally, and stay involved every step of the way.
What membership actually means
Direct access to your doctor.
Reach Dr. Casey or Dr. Nelson via secure message, phone, or video — no call centers, no triage nurses, no runaround. When something's urgent, you hear back from your actual physician.
Urgent care at your own practice.
IV fluids, antibiotic injections, imaging coordination, in-office lab draws — handled by the doctor who knows you, in a familiar setting. Not an expensive waiting room full of strangers.
Physicians who cover for each other.
If Dr. Casey isn't available, Dr. Nelson steps in — and vice versa. You always have a physician who knows your chart, not a stranger starting from scratch.
Transparent, predictable pricing.
One annual membership fee. No surprise bills, no insurance claim denials, no co-pays at every visit. You know exactly what your care costs — and what you get for it.
Care for the whole family.
From newborns to grandparents, both physicians see all ages and all genders. One practice, one relationship, for your entire family, across every stage of life.
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.
