It is clear that Josh is here to learn all he can from you so he can offer the best option for you and your pain. Ive been a patient of Josh's for a few years now. He understands CRPS better than many do and he has helped me tremendously with both the mental and physical affects of my condition.

I was having more issues thanks to a shift in my spine causing a change in my mobility. He took the time to explain how things work. He is careful asking where do you think I should go. Overall a positive experience. Thanks to Liam as well for making sure I stayed safe getting on and off the table!
