These qualities are not only evidenced by his advancement to Latham (and his many clients who have followed him), but Gary is able to navigate consensus where conflict would be naturally assumed. Further, his leadership, or perhaps just in the merging of styles, I have found that his partners in environmental matters across the firm have had a consistently reliable affability, giving clients the confidence to trust Latham, and even sometimes just themselves, with a curated path to resolution.’

‘The team has taken the time to learn our industry, which I consider Ground Zero of environmental litigation in California. That knowledge extends beyond the law to the technical processes that are increasingly controlled by regulation. Jeffrey Dintzer is known in the environmental community as a force to be reckoned with. He’s the attorney that you want on your side in bet-the-farm litigation. I’ve witnessed his compelling oral argument, with quick and insightful pivots in response to judges’ questions.’

‘Matt Wickersham never says no when I call with an urgent request. I’ve seem him easily absorb complex financial data from one interviewee and dense technical data from another interviewee in the next hour. Finally, he’s always willing to consider my outlandish ideas and help me think them through.’

‘The people at Alston and Bird are their greatest asset. They are capable and inventive in all of the legal issues that we have faced. The partners are all incredible litigators. The associates are all extremely sharp and organized. Alston and Bird is great with putting specialty people in positions for us to succeed. They are capable of recommending experts. They also work great with our contractors and bridging the gaps between our work and legal issues.’

His ability during litigation to improvise and adapt to some of the absurdities that we’ve faced in court have been truly impressive. Nowell Berreth is another partner that I’ve worked with for almost 9 years. He is always poised in any situation that we may request last minute. Phil Sandick is an associate that helps manage our contractors and organizes and track every aspect of our cases.’

‘The Alston & Bird Team has a thorough understanding of the law. You can tell when you discuss an issue with them. They will do the necessary research to confirm, but on land use issues, no one else that we have used compares (and I have had experience with many). Clay Massey and Meaghan Boyd are the two that I have the most contact with in the firm now. These folks are fun to work with and they think well on their feet. I have found their work to be very thorough and they bring the most up to date perspectives on the law.’

‘The team is very responsive with a focus on meeting the client’s needs no matter the inconvenience or hardship. The team is very skilled from a substantive standpoint and proficient at explaining the cases, risks, legal analysis in terms that can be easily understood both by in-house counsel and non-lawyer participants. The team is honest – they will tell the facts no matter if they are good or bad – there is never and issue with gilding the lily and telling the client what they might prefer to hear. In these respects I would say the team is above similar firms that provide services to the company. The team is receptive to suggestions from the client on how the staff and structure the team that does work for the client.’

‘The Alston & Bird team is special because its lawyers are very experienced trial lawyers, and also possess a great deal of legal expertise in the environmental law arena. Jeffrey Dintzer is one of the best environmental litigators I’ve worked with at any firm across the country. He’s smart, practical and tenacious. He pays attention to detail, is an very effective writer. He’s really persuasive in court and is a very strong communicator. His team supports him in all necessary ways.’

‘The team includes experts who can advice on the front end of environmental compliance and real in-court litigators on the back end to defend as well. The complete team is the best in the state. The team advised on the largest CEQA EIR in California’s history and has the best track record against baseless activist lawsuits. Jeffrey Dintzer is super knowledgeable, aggressive and he runs a lean, cost efficient team.’
