Dr. Oh and his staff are wonderful and his associate Angela Young diagnosed me with MG after everything had been normal. This came from a single fiber emg. Dr Oh mainly oversees the emg clinic but his associates are wonderful. What a relief to get a diagnosis and learn to deal with it and know it is not in my head. I also went thru the cardiologist and pulmonology thing too. Good Luck!! You may email me if you like for more info.
