Dr. Mastrin is awesome. She is a no bulls*** lady. If you have all your ducks in a row she's there to help. I have read reviews on other sites about her and I was so scared. Just going to a pain center is scary. Her staff made me feel so welcome. She took the time to explain to me what my other doctors didn't about my condition with degenerative disc disease and herniated discs and why I have my pain. She has me on the right track to getting better. All the haters that posted bad reviews were people expecting drugs when they couldn't prove their pain. If you want someone on your side she's your doctor.
