My company recently worked with Bailey to place a hard to fill role that had been open for years. We would highly recommend him based on our recent experience partnering with him. He was truly exceptional to work with from start to finish. Throughout the entire process, he was incredibly responsive, kind, and always open to conversation whenever we needed support or clarity.

Principal Civil Design engineer – MWH Treatment

Thanks a million, highly recommend, five stars! The team responded to my request for a new contract role quickly and efficiently despite the less than ideal timing in terms of industry activity. They sifted through the market on my behalf to avoid wasting my time and reducing my effort to a minimum, keeping me very well informed throughout the search before securing a perfect role for me in record time.

Alexander Associates and I have been in regular contact and communication over the years with regards working together. This year we were finally able to do that and it has been a pleasure to be working with the team. Very efficient in putting together the contract and listening to my concerns and needs.
