I think I speak for everyone when I say that we could not have settled this case without the tremendous efforts of Judge Brown. He was so kind to my clients and he really helped them through this difficult process.  His thoughtful approach and his incredible tenacity really made the difference in this case. We were very lucky to have him as our mediator and we look forward to working with Judge Brown again very soon.
