Organizing areas of law into targeted industry teams enables us to concentrate on specific business issues and marketplace trends. Serving as trusted advisers and advocates to a full spectrum of clients, our lawyers deliver the legal insight and innovative solutions needed to create a competitive edge for businesses locally and worldwide.

Industry teams at Armstrong Teasdale work together to serve current and future clients in the following ways:

  • Create and distribute notices to alert clients on how new regulations will impact business operations.
  • Foster opportunities for open dialogue and conversation among business leaders, rule-makers and other lawyers in the industry.

While our industry teams are designed to facilitate shared industry knowledge across practice groups to serve a broad base of current and future clients, our client teams include lawyers from each practice group who serve the same client.

“I wanted to find a place where I could grow my practice and work with good people. It was clear from the beginning that management lived the firm’s values, many of which happen to be my personal values, so I knew it was a good fit.”
