Client feedback

There is no ego; just a singular focus on getting the right result.”

I’m a Senior VP with an accounting and finance background. I’ve worked with lawyers and large law firms. It is very rare to encounter lawyers who combine expertise, dedication, and a businesslike approach to litigation.

Counter’s representation on our behalf was well-informed, professional and efficient, which ultimately resulted in a highly satisfactory decision in all aspects.
