Calvin Matthews, a member of the Corporate Services practice group, serves as outside counsel to a number of businesses ranging from closely held businesses to publicly traded companies. In these positions, Calvin 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.

He 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. Because of this, Calvin has a diverse practice representing clients ranging from high net worth individuals to a variety of companies from industries as different as apparel, banking, real estate developers, and property owners and managers. Given Calvin’s level of involvement with a vast majority of his clients, he spends a large part of his practice working directly with the owners, boards of directors and senior management.

In the corporate services area, many of Calvin’s clients are mid- and large-sized closely held businesses. He takes a holistic view of a company’s operations and thus provides a wide range of needed services, including the review of corporate structure, various commercial and employment contracts and internal policies. He develops strategies aimed at improving operations and minimizing risks. With many clients, Calvin is involved with and ultimately responsible for all of the entities’ legal needs.

When clients face litigation issues, Calvin employs his experience handling various commercial litigation matters for more than a decade. His experience includes commercial contract, insurance, banking and financial matters, member and shareholder litigations, as well as complex multiparty national class action cases. His widely publicized cases include the representation of Jos A. Bank Clothiers Inc. and The Men's Wearhouse, Inc. against various national class actions; the representation of multiple board members of an international military defense company; and the representation of the CEO and president of a company in one of the largest fraud schemes ever prosecuted in the Missouri.

Calvin’s knowledge and work extends to the representation of financial institutions and other lenders, including banks in the negotiation, documentation and closing of loan transactions. He has significant experience representing financial institutions in tax credit assisted development transactions, with a focus on Low Income Housing Tax Credits (LIHTC) and renewable energy.

Calvin also spends a significant amount of time representing entities associated with the development and management of affordable housing developments and solar energy projects.
