The work you are doing is very important. As an interventional pain management physician I am always looking for non invasive ways for patients to improve their health and pain.

I first learned of you from Peter Attila's Podcast. I was so intrigued by your work. Thank you!

Thank you so much for all of this incredible information you put on. From the first time that I erased myself in an ice bath I went in to total shock and had no idea about the physiological effects that were occuring. After reading your first book and listening to many of your podcasts I now use this information to help men tackle mental health issues in my Men's group events.

Love your story, heard you on many different podcasts and you got me talking cold showers and talking about it to many of my patients. Keep up the great work!
