ZEK's clients range from some of the largest, most prominent corporations and financial institutions in the world, to small privately held companies, to individuals.

We are proud of the diversity of clients which, we believe, reflects the diversity of our practice. We are equally proud of the fact that many of the Firm's client relationships stretch back to the Firm's inception. We encourage prospective clients to contact existing clients, such as the ones listed here, to discuss ZEK's strengths and capabilities.
