I engaged ZSA because of their strong candidates and professional approach.  My experience with Mike was excellent.  He was always very responsive and easy to deal with.  He finds us excellent candidates and knows the calibre of people we are looking for.  His easy going nature; his appropriate follow ups; and, updates on where candidates are at in their process, were all valuable and helpful.  I have used other recruiters in the past but ZSA is always the most professional in their approach and brings us the best candidates.  I like that ZSA vets candidates thoroughly before presenting them.  I would use the services of ZSA again.
