Euripides wrote "Every man is like the company he is wont to keep." At Opus One, we are proud of our client list because we feel that it demonstrates the quality of the work we do. We work with a wide variety of organizations on an equally wide variety of tasks, from 2-person brokerage firms to the largest of the huge. Here are some of our most interesting and recognizable clients, along with a rough description of our involvement with them. Opus One also does security consulting; our clients in that area normally ask us to keep our relationship a confidential one, so most of their names do not appear here.

If you would like an idea of what exactly it is we do, you can also look at our consulting projects list, which gives a little more detail on the kind of things we have done and are prepared to do.
