‘After 25 years in private equity, I have worked with countless senior partners at top-tier law firms, but I have only developed one strategic, go-to, legal relationship. That relationship is with Lawrence Elbaum, Co-Head of Vinson & Elkins’ (V&E) shareholder activism practice. In the last four years, Lawrence has been involved with 6 of my portfolio companies, including for over 30 complex governance/management situations, 7 proxy fights/activism campaigns, 3 divestitures, 6 financings, and 1 NASDAQ uplisting.’

With Lawrence, there is no start or stop time, he is constantly accessible. There is no ego or drama working with other lawyers, either at his firm or competitive law firms. He humbly refers less familiar issues. Uniquely, Lawrence doesn’t take advantage of client challenges but rather keeps in mind his clients’ long-term objectives and establishes and maintains fair billing and fee structures. As such, Lawrence has built V&E’s industry-leading activist practice. True to form, the practice has only thrived under Lawrence’s leadership.’

‘I enthusiastically endorse Lawrence Elbaum for his pristine track record of success, ethical leadership, and tireless efforts to solve client problems.’

‘Everyone on the team is extremely intelligent, gifted writers and excellent communicators who provide creative solutions to our litigation matters.’

‘During the course of a mediation, our mediator, a former judge, went out of his way during the course of our discussion to describe how our lead lawyer was the best that he had seen during his tenure on the bench. We happen to agree. (Michael Holmes, VE partner from Dallas).’

‘Jim Mathias is a masterful litigator and trial counsel. He has all the legal skills and more. Jim is an effective leader of the legal team and the client relationship.’

‘Ben Schuman is a master in his own right. He is pleasant and unassuming, yet possesses a powerful intellect that commands respect. He has a winning way with clients.’

‘Over the two years of this litigation Meagan Pace grew from role supporting Jim and Ben to a fully participating trial lawyer who prepared and examined an important witness. She will no doubt be placed in a senior role in the near future. Most importantly, this team developed a devastatingly effective trial strategy in a matter that required creativity to succeed.’

‘My extended family and I engaged DLA Piper to represent us in major litigation involving protection of our rights as minority shareholders. It was destined from the beginning to be a major battle. I appreciated the fact that DLA initially investigated our claims fully and obtained expert advice as they evaluated the case. They were realistic about how they assessed the case and worked with many different personality types within our group of 14 plaintiffs to arrive at a course of action.’

‘They managed our expectations very well. Their management of the litigation process thoroughly outclassed the attorneys in opposition, even though opposing counsel too was from a notable big firm practice. As trial neared, they did and outstanding of preparing 14 people in the plaintiff group for depositions and for trial. I thought the way they organized their trial presentation was masterful, involving witnesses of different ages and backgrounds, and 3 lawyers of different experience who could together articulate a narrative of our equitable claims.’

‘I was particularly impressed by our the attorney team collaborated with one another, and that presented a united front at trial. It also meant that they were at all times far better prepared than our opponents. I think that thoroughness reflected very well to the judge and is why I would recommend DLA without hesitation in the context of large cases that are of a “bet the farm” nature.’

‘They developed a financing strategy for the case that meant we were able to see it through to the end without feeling undue pressure about fees, which denied the defendants the ability to pressure us into a subpar settlement. My family is very very happy with the result ultimately obtained, and we credit DLA with having made it happen.’

‘Jim Mathias – is an exceptional litigator and team leader. With careful assessment early on, he was able to develop a strategy that really matched the need in terms of creating pressure on defendants whose game plan was always to stall and be noncooperative. I like the fact that Jim was able to collaborate fully with his juniors and provide opportunities for them to contribute fully. Building that infrastructure in his team made a huge difference.’
