Not to Beth Israel, but if you can come to NYC and you are concerned about ALS - you should see Dr. Lewis Rowland. He is the authority not only here in NYC, but hugely reknowned in the world - he founded the Eleanor and Lou Gehrig ALS Center at Columbia Pres. - and has been seeing and doing nothing but ALS and mimics for over 30 years. AND he is the nicest, sweetest most lovely man - his office is great. Prett easy to get an appt. actually.
