Pain Institute of Southern Arizona- PISA, is my provider. I have been with PISA for several years and I have never had a problem with America Ramirez or Dr Cornidez. They are both excellent at the leval of care I receive from them, each and every appointment I have had with them. You can relax and put your care in their hands, trusting that your care will be the best from them. I have always given them a 5 star rating. Everyone at PISA works to give you the best care possible. Thank you.
