HI
I'd recommend Dr. Katzin or Dr. Vu at the Tampa ALS clinic. They are through South Fl. University Hospital. Both are neuromuscular and motor neuron disease specialists. Takes about a month to get in to see them.
DR Katzin, I know, prefers to do her own testing as far as EMG/NCV goes--so don't waste your time or energy having it done elsewhere. They are close for you--two hour drive for me to see Dr, Katzin. I thought she was very good. I know nothing personally of Dr. Vu, though he's the co-director of the ALS clinic. Both are recommended by the ALSA and I was personally recommended to her by the ALS counselor in my town.
