Dr Mammen is one of the best in the country to see for my extremely rare neuromuscular disease. He is my last hope for a diagnosis as he truly understands rare atypical disease related to myositis. My presentation is more atypical than anyone has encountered including Dr Mammen.

Dr Mammen has been my Doctor since 2007 when the Myositis center opened at JH. He returned quality of life back to me I was very ill with Dermatomyositis at the onset of the disease and was not effectively treated for it until I arrived at JH myositis center. Dr Mammen is the best doctor in the Universe. Its not only his knowledge and skill but his amazing personality.
