    Jonathan and I have worked together developing a submission to the Internal Revenue Service on behalf of our client, a whistleblower. He is a very fine attorney who regularly achieves outstanding results for his clients. Jonathan is very clever in terms of being able to think outside the box--always a major plus in litigation. He is a good writer and has excellent attention to detail. Sound judgment and very effective communication skills.
