Prominent Assignments

Primarily responsible for litigating a commercial breach of contract matter where the plaintiff asserted more than $10 million in damages against our client. As part of that matter, engaged in extensive discovery and motion practice, including successfully arguing two motions to compel in the Eastern District of Michigan, resulting in favorable settlement on the client’s behalf.

Worked on a multi-million dollar trust litigation matter brought against our client, researching and identifying the pertinent legal argument, which resulted in all claims against the client being dismissed with prejudice.

Participated in several trial teams that resulted in favorable outcomes for the client, including employment discrimination claims against the University of Michigan.

Worked on a number of financial services matters on behalf of lenders relating to commercial properties in various states. These cases have included day-to-day case management, responding to discovery, and drafting dispositive motions.
