You are unique.

Your healthcare should be too.

Personalized medicine
for long term wellness

Health and well-being are complex. We know we deserve more than a one-size-fits-all approach to medicine but, too often, the routinized, assembly-line care provided in standard offices gives us just that.

At Tendwell, we take a different approach. Before we even get started on treatment, we take time to develop a deep understanding of each patient’s unique risk factors, genetics, environment, outlooks and histories. Equally important: we listen carefully and work collaboratively with patients - after all, many patients with chronic conditions come to us after many frustrating attempts to get real attention from standard practitioners.

Armed with the right information, we develop individualized health plans tailored to the precise factors at the root of dysfunction.


We address root causes,
not just lists of symptoms

We start with a comprehensive assessment of your health—and we mean comprehensive—going far beyond the approach taken by standard practices. We probe deeply into your medical history and concerns and, in most cases, we use specialized lab tests (hormonal, genetic, microbiome, etc…) for deeper insights into the root causes of dysfunction.

We then collaborate with you to create customized health plans to address chronic illness, to optimize long term health, and to get you to a place of wellness. And we don’t leave it all up to you to get better: we continue to support you with coaching and regular support visits to make sure your plan is working and to address any issues as they arise.
