As a college trumpet player, Jonathan never had trouble picking which band he would play in, he simply joined them all. He could be found among the marching band, wind ensemble, chamber orchestra, and jazz band, usually as the leader or principal trumpet in each. He has put the same philosophy into practice as a lawyer.

Jonathan spends most of his time representing a diverse set of clients, including manufacturers and distributors of machinery, appliances, consumer electronics, and medical devices, as well as retailers, mortgage servicers, telecommunications providers, and energy companies.  In the financial services industry, Jonathan has also represented clients in a variety of rarely-seen proceedings initiated by the judiciary, attorneys general, or other government bodies.
