Patient Comments (1)
|
NOT TRUSTWORTHY. He is a marketing agent for Medstar/Georgetown's Lombardi Cancer center & the chemo producing pharmaceuticals. He sweet talks you in during the 1st visit & later he uses the patients to train his fellows & residents. He gets you started with the fellows & residents, then he will spend 90 seconds with the patient. He will not guide the patient towards the cure if procedure is not available at Georgetown & money cannot be made off a patient. He thinks of himself as a CELEBRITY.
