Umass has a good clinical program from what I heard and also has transplants. The only downside is location- Worcester. It is also close enough to Boston that there may be competition for patients.
Another NE program in Boston is Boston University. I went to BU for an interview and think it is a great program. They rotate at the Boston Medical Center, and the Boston VA hospitals. Despite being in the same city as the Harvard programs and Tufts, they do not have to compete for the same type of patients as BMC serve mostly the underserved population. There is good clinical exposure and opportunity for clinical and basic science research. They also have an interesting Geri Onc track (one of the first geri onc programs in the country. I think it is 3 years to be double boarded in geri and oncology and 4 years to be boarded in heme as well). BMC is also an international referral center for Amyloidosis (one of 2 in the country, the other being Mayo) and the hem onc program does a lot of bone marrow transplantation and chemotherapy to treat this condition (which I did not know you could before). The faculty seem supportive and fellows happy to be there.
