I engaged Warren Bongard of ZSA as colleagues spoke highly of him from previous engagements. Working with Warren was excellent.  He is professional, flexible, and has been effective for us. What I found to be of value in the hiring process was the high quality candidates, greater volume of candidates, and it was all well coordinated. Warren’s experience and his appreciation for our high-bar needs was key. I would use ZSA again in the future.
