I have been a patient of Pain Institute of Southern Arizona for several years now. I am so happy that I found this facility for help with my chronic back pain. Gemma has never let me down, she is always looking for different treatments that might help me. Gemma Lopez MPAS, PA-C has never doubted me, and I cannot give enough praise to Gemma for her unwavering support and compassion. I would highly recommend this facility to anyone who is struggling with pain issues. Gemma has always been there for me, as well as Dr Yelavarthi and Dr Henry. You cannot find another pain management specialist who can even come close to the support, the compassion and the never ending options to help with pain as the Pain Institute of Southern Arizona.
