Joseph A. MacLellan M.S., M.A., PA-C, Founder

​

It hit me in my early 50s—
Not a diagnosis. Not a scare. My own mortality.
The quiet realization that I was running out of time.

I’d spent 15 years in emergency medicine watching people lose everything—mobility, memory, identity—because they waited too long.
So I built a system to take control. This isn't your primary care office. This is preventive care, total health optimization.  Fitness and Nutrition Focus. 

Genetics. Epigenetics. VO₂ max. DEXA. Biomarkers. MRI. Glucose. Cancer detection, BHRT, peptides, supplements.  A bespoke health longevity plan.  


I mapped out exactly what I needed to do to maximize my years and I went all in. 

The results changed my life.


I feel stronger, sharper, and clearer than I ever have. I now understand the path to better health, more energy, and gaining more functional years. 

I realize there are no guarantees but I believe in putting the probabilities in my favor.

  
Then people started asking me to do the same for them.

That’s how Eternaal Health began.

This isn’t about living forever (although you will live longer).
It’s about staying fully alive while you’re here.

If you’re not ready to drift toward decline…
If you want to live longer, fight for every extra year, hike with your grandkids, be a high-functioning 90-year-old, get every ounce of strength, every bit of clarity…
Then this is the work.
