What Our Clients Are Saying

Mr. Axenfeld went beyond the call of duty for us against a large corporation trying to bully us out of the marketplace by filing multiple lawsuits at one time. Axenfeld stayed by us the entire time, fought hard, and eventually forced a settlement. We now have peace in the marketplace allowing us to compete on a level-playing field. Can’t recommend him enough.

– Mike M. (CEO of a Medical device company)
