Some sort of data gathering place called enclarity.  They collect healthcare provider information and then use their database to sell information services.  They've called our office repeatedly, and gotten nothing from us; we do not ever give out information without a signed authorization from the individual employee.  Then they started sending dozens of faxes, one for each person's name they could get from any source, all of which we have shredded.  Pains in the butt, and having a hard time taking no for an answer.  We've been given the go-ahead to hang up on them in the future.  Will continue to post as other numbers are used by these pests.
