"It was Tammy's great idea." (Blair Cohen)

Fifteen years ago, [Tammy and Blair Cohen] left secure, well-paid jobs for the insecurity of their own business.

"The first client we got over the telephone and didn't know what we were doing was Toys R Us. I came home and [Blair] said, 'I think we landed Toys R Us. We've got to figure out what we're going to do here.'" (Tammy Cohen)

Figure it out they did. With a large new building and now nearly 10,000 clients.

"Screening is weeding out the bad appliants before they get into a workplace." (Tammy Cohen)

The Cohens recruit their own employees through both ads and referrals.

"They care about the employees — that's the biggest thing. I've had ups and downs, and they stood by me when I had a few downs." (Mike Haffey, InfoMart employee)

"There are so many different people that work here. Black, white, hispanic — just a very diverse group of people." (Althea Holmes, InfoMart employee)

75 employees now, and look at this — all these empty cubicles. They are ready for even more growth!

"Our passion is to have the biggest and the best pre-employment screening company in this industry." (Blair Cohen)

"You know, our five-year plan is to keep growing and to have everybody happy." (Tammy Cohen)

The Cohens say the need for increased security these days is one of the reasons InfoMart is experiencing such rapid growth.
