Had my screening and checked out fine, Went in for the study and for a study needing 10 people they scheduled 45 people to come in and be available. The next thing I see is nurses coming in and telling one person after another that they wouldnt be able to take part in the study. In short, They had me thinking I was all set to make the money for my wifes car, then yanked the rug out from under me for no good reason!!! Also, they then tell me I cant re-apply for a study for 4 weeks. This place is crooked, Go to Vince & Associates!!!
