Dr. Tresser is a superstar! I underwent a two staged procedure for spinal fusion with interbody cages at 4 levels then 2 days later rod placement for spine curvature.  The surgery was very successful and I was taking Tylenol for pain after 2 weeks.   I was basically unable to walk any distance without having to sit before surgery…that pain is gone!  Thank you Dr. Tresser for your excellent care.
