Input Needed - Rehab Centers in MA?

Good afternoon, I thought that perhaps you guys in MA could help me.  Does anyone have any personal experience with any of the rehab facilities that specialize in the needs of the morbidly obese?  Whether you were a patient, knew a patient or are familiar with the environment, all input is appreciated.  The specific facilities that I am inquiring about are:

Berkshire Health Systems - Pittsfields, MA Hillcrest Commons Rehab Center - Pittsfield, MA

Thanks in advance
