I wanted to post about Dr. Jonathan Bayuk who is part of Hampden County Physician Associates. He has a fair number of Mastcytosis/MCAD patients. He lectures in our area about these diseases and he has a good relationship w/ the MDs in Boston. He does his own bone marrow biopsies and from my 1st visit w/ him he seems to have a compassionate heart.  He didn't bat an eye at my symptoms or at my coming it to discuss MCAD issues.

He works out of 3 offices in the area: Westfield, Northampton, Springfield.  The Northampton number for him is: 413-584-4010.
