Kalvin is fantastic. Both him and Concentric have helped me out with everything, from going through the process to getting me a contract to finding somewhere to stay. I would definitely recommend to anyone interested!

I can't say enough good things about Kalvin and Concentric. Kalvin expertly and efficiently helped me navigate through the hiring process. He was readily available to answer my questions. Even now he periodically keeps in touch with me to make sure things are going well. Awesome good experience in every respect!!

In 30 years of medical imaging, I've been recruited a heap. Kalvin is my recruiter. Yet, he's never pitched me. He's never got me to sign onto an assignment, and then shorted me somewhere after I'm all in. (happens a lot) He's typically way ahead of the process and kindly about a heads up when I need it. Something is due shortly; an annual renewal, paperwork, a time sheet. (some times we ARE just crazy busy) Little or big, Kalvin is on it. Even keeled. A fantastic go between when you're busy doing your part. Kalvin has been spot on from the day I met him. I've been with Concentric since early 2000. My only Agency in 10 years. It's been good. And it is good. Thank you Kalvin. Thank you Concentric.

Kalvin is the best agent! Kalvin assisted me on my very first out of state assignment. I was very nervous and unsure of things because of my unfamiliarity. He made my transition very smooth and uncomplicated. He also helped me with having a place to stay upon arrival, he did very well in communicating with all the involved parties. Kalvin is very good at getting you the pay want, and negotiating contracts. Kalvin is the #1 agent, and I would definitely recommend him as an agent and his agency for any contract assignments.

Kalvin is by far the best recruiter I have ever worked with. He’s very professional and very knowledgeable in his field. I also like that he keeps up with checking in on his recruited team and always gets back with any questions or follow up information. He’s a very nice guy and easy to speak with. I would definitely recommend Kalvin as recruiter.
