The doctor that diagnosed the AN initially was from Springfield, Dr. Jacobs. He then referred me to Dr. Poe in Boston. He and Dr. Barker were the two that did my surgery. Dr Loeffler was the doctor for the radiation. I have Health New England for insurance and everything had to go thru my primary Dr. Health New England then assigned me a case manager, she was terrific. Had no problem getting as many opinions as I wanted. I would do the research, ask my primary for a referrral, his office would fax it directly to the case manager and she would walk the referral thru whatever channels it had to go thru. She was a gift during a very difficult time.
