TURN RECOVERY INTO A LIFESTYLE
SubZero Cryotherapy was started with a vision for an alternative to medicine and to help others live a longer, healthier life.
Founded and owned by Natasha Miller, SubZero Cryotherapy first opened its doors in Greeneville in November 2022. Just two years later, driven by rapid growth and strong community demand, a second location proudly launched in Johnson City in November 2024.
​
What began as a cryotherapy studio has evolved into a comprehensive recovery, wellness, and longevity destination. At the request of our guests, we expanded our offerings to include Far Infrared Sauna Therapy and advanced Red Light Therapy with Near Infrared (NIR), seamlessly complementing our Lifestyle services. Continued demand led to the addition of highly sought-after Specialty treatments such as Body Sculpting, Fat Freezing, and Cryo Facials.
​
SubZero Cryotherapy is a locally owned small business, built for the community and constructed from the ground up by the SubZero Cryo team. We are committed to continual growth and innovation—bringing our guests the most advanced, non-invasive technologies available to support performance, recovery, health, and long-term longevity.
Natasha's story
I am a proud mother of two amazing children, a Registered Nurse, and a Cryotherapy Specialist. My nursing career began in high-acuity settings, including ICU and PCU, Peri-Operative care, and Traumatic Brain Injury units. Most recently, I served as Director of Nursing and Executive Director of an assisted living community during the first two years of COVID—one of the most challenging and defining periods in healthcare.
​
Throughout my career, I was fortunate to be trained and mentored by exceptional healthcare professionals. I developed a deep passion for working with individuals affected by traumatic brain injuries, dementia, and Alzheimer’s disease. Caring for patients who had limited ability to verbally express their needs taught me to recognize how pain, anxiety, depression, and emotional distress often present through behavior rather than words.
​
Helping others navigate difficult seasons of life has always been at the core of who I am. SubZero Cryotherapy has given me the opportunity to continue that mission—providing relief, recovery, and support in a non-invasive way, without reliance on pain, anxiety, sleep and so many other medications. Through this work, I am able to blend clinical knowledge with innovative wellness technology to help clients feel better, move better, and live more fully.
