has called my  employer several times. possible employment verification? other calls from:
408-680-2571
408-680-2569

This is a phone number for Triple Crown Consulting. I've worked for them as an IT contractor several times. If they called you most likely you have a resume posted on a job board which matches one of their current openings.

This is Triple Crow Consulting. They are very aggressive to the point of harassment. Have asked them to take us off their list and to quit calling.
