A doctor from New York flew to Houston to help take care of those at the evacuation center and was frustrated at the level of bureaucracy. He had a copy of his medical license and his qualifications could be verified online at the New York government website for licensed medical professionals. It was taking some time to get approved to volunteer. The doctor (a family practitioner) is also a retired New York Fire Department lieutenant who survived the 9-11 terrorist attack. He said he experienced the help that poured into his city after the attack and this is his way of returning the service. He flew to Houston at his own expense and wished to remain anonymous.
