Deep Roots

One aspen tree is actually only a small part of a larger organism. A stand or group of aspen trees is considered a singular organism with the main life force underground in the extensive root system. Aspen trees have deep roots. If a forest fire brings down the trees it would appear that all was lost. But the root system in aspen trees are so strong and deep that in the right conditions even after a massive forest fire, aspen trees can quickly grow and repair into a lush forest. Similar to our health, we have the roots to thrive and optimize our lives. Like the roots of the aspen, our bodies know how to replenish and heal when given the opportunity.

Male & Female

Aspens are dioecious plants, which mean that male and female flowers develop on separate trees. At Aspen Grey we believe that men and women therapies need to be customized to their unique needs. From longevity to weight loss, each approach solves your unique needs.

Long, Strong Lives

Older than the massive sequoias or the biblical bristlecone pines, the oldest known aspen has lived more than 80,000 years on Utah’s Fishlake National Forest. Not only is the tree the oldest living organism, weighing in at an estimated 6,600 tons, it is also the heaviest. Even if the trees of a strand are wiped out, it is very difficult to permanently extinguish aspens. 

Growing up my family vacationed every summer in Colorado. As I have expanded my practice, I have come to realize how much the aspen trees from my childhood are symbolic of my own health. There was a time in my life that I wasn’t as healthy, but like the roots of the aspen tree, my body knew not only how to be well, but how to thrive when given the right opportunity.
