     Dr. Tredway performed a minimally invasive procedure on my low back, L4/5, and 2 months later I was nearly pain free.  This was a big decision for me since I live in Idaho and there was extra expense and effort to travel to Seattle for the procedure. 

     I am supremely satisfied and am at ease knowing any future spine care that I may need will be handled by Dr. Tredway.  I am an RN by profession and would enthusiastically refer anyone to Trent
