June 8, 2020 Press Releases

Armstrong Teasdale announces the election of three partners to the firm’s Executive Committee, which functions as the governing board of the firm, as well as three partners to the Compensation Committee, which is responsible for the allocation of compensation to firm partners.

Partners Christopher M. Goff and Mark L. Stoneman have each been re-elected to the firm's Executive Committee for a three-year term. In addition, Partner E. Calvin Matthews, IV has been elected to the Compensation Committee for a two-year term. Partner Michael S. Jefferies was re-elected for a three-year term.

A member of the firm’s Intellectual Property practice group, Goff helps large companies secure, protect and enforce intellectual property rights. With an emphasis in medical device, chemical and biochemical patent preparation and prosecution, he counsels clients on freedom-to-operate issues, patent infringement issues, patentability and other due diligence issues. Goff recently won a multimillion-dollar, multiyear contract to represent the National Institutes of Health. In addition, he has been recognized among Chambers USA’s Leading Lawyers for Business for Intellectual Property in Missouri for nearly a decade and is currently ranked in Band 1. This will be Goff’s fourth term serving on the Executive Committee.

As leader of the firm’s Corporate Services practice group, Stoneman is responsible for coordinating with the firm’s managing partner to strengthen the group’s planning, execution and operational practices. In his law practice, he facilitates the structuring, financing and completion of acquisitions, mergers, divestitures, joint ventures and partnerships. Stoneman’s background in accounting and finance helps him to ensure that the agreements related to these transactions are consistent with his client’s goals and expectations with respect to financial matters, which can be of critical importance in transactions of this nature.

A member of the Corporate Services practice group, Matthews serves as outside counsel to a number of businesses ranging from closely held businesses to publicly traded companies. In these positions, he handles a wide range of corporate issues including those related to financial transactions, real estate, employment and labor, mergers and acquisitions, corporate governance, and various types of litigation. Matthews offers clients a unique combination of skills due to an unusual background that includes in-depth experience as a corporate services attorney, litigator and multiple years in the financial industry.

Jefferies works with clients across multiple industries on matters related to business operations and growth. His practice is primarily focused on mergers and acquisitions and other corporate development transactions. In connection with his M&A practice, Jefferies has experience with the use and structuring of representations and warranties insurance, and has worked with various insurance brokers to place and negotiate these policies. He also has experience representing clients involved in post-closing transaction disputes, including those relating to working capital, purchase price adjustments and indemnification claims. Jefferies is chair of the firm’s Technology Committee and is also a member of the firm’s Opinion Letter Committee.
