One Tree Integrative Medicine
We are all the leaves of one tree.
One Tree is a root-cause-focused integrative medicine practice in
Evergreen, Colorado, founded by Jamie Lewallen, PA-C, PhD. We find the
root cause behind chronic and complex conditions when conventional
tests come back "normal." New patient appointments start at 60
minutes. In-person in Evergreen, CO and via telehealth across
Colorado. Cash-pay / out-of-network; appointments start from $90; free
initial consultation.
Every test came back normal. You still feel terrible. That's not in
your head.
You've seen the specialists. You've done the tests. And you keep
hearing the same thing: "Everything looks fine." But you know your
body. Something is wrong. At One Tree, we believe you — and we have
the tools to find the answer.
