How likely are you to recommend Dr. Masem?

(Select your rating)
I had a traction injury that I went to many doctors for help with. Pretty much none of them were able to even identify the problem until I went to Dr. Masem. He immediately knew what the ailment was and how to treat it, while other doctors knew nothing about my condition. Overall, I am impressed at his medical knowledge, even by doctor standards and highly recommend him for any hand related issues.
