My name is Dr. Timothy Dugas, D.C. and I have been extremely blessed and fortunate in life that I can proudly say that I am following my life’s dream.  My personal mission is to change as many lives as possible and to help elevate the consciousness of humanity.  I’ve helped many people that have lost hope, that are searching for answers to their health questions and concerns, and that feel bounced around the healthcare system.  I “Serve All and Love All” similar to the spiritual wisdom of Mata Amritanandamayi, also known as Amma the “Hugging Saint”.  After experiencing an embrace from her firsthand, it’s impossible for me not to appreciate her selfless love and compassion towards all beings.  My goal is to inspire, uplift, and transform peoples lives through connection of human touch and the power of the Chiropractic adjustment.

In the words of Krishnamurti, I know that just “as a pebble thrown into a calm lake creates an ever-widening circle, so the action of energy in the direction of what is true creates the waves of a new culture.”

With open arms and a loving heart, welcome to Atlas Specific!

Hello, I’m Dr. Danielle Donarski, D.C., a Minnesota native who is thrilled to have become a member of the Durango community. 

After earning a Bachelor’s Degree in Psychology from the University of Minnesota, I knew I wanted to pursue a more tangible way to help people heal their bodies and minds naturally. In my search for the best way to help people, a couple of incredible Chiropractors introduced me to Chiropractic Philosophy. When I learned that Chiropractic is based on removing interference in the nervous system to allow the body the best opportunity to heal itself from the inside out, I knew I had discovered a discipline worthy of lifelong study. Soon after, I enrolled at Life Chiropractic College West in Hayward California where I also trained in nutrition and functional neurology.

My passion is using gentle, effective Chiropractic techniques to address and correct interference in the nervous system so you can experience life at 100%.
