She has extensive experience representing domestic and international companies from numerous industries, including manufacturing, retail, biotechnology and life sciences, technology, health care, hospitality, animal health and agtech, aerospace, finance and professional services. As outside corporate counsel to businesses, Jennifer provides counsel on day-to-day transactions as well as high-stakes disputes and transformative relationships. In that role, she is adept at efficiently coordinating experience from other segments of the firm, such as intellectual property, lending, real estate, employment and litigation.

She also serves as Missouri local counsel to out-of-state entities engaged in significant transactions involving Missouri companies.

Securities and Corporate Finance
Jennifer has broad experience advising publicly traded companies about securities offerings, Securities Exchange Act reporting issues, national securities exchange listing issues and various compliance and disclosure issues. She also counsels privately held companies raising funds through private placements of securities, compensating employees through equity-based compensation and financing their growth and operations through debt financing.

General Corporate
Jennifer draws on her accounting and business background to assist clients in successfully achieving their financial and business goals through investments, joint ventures, strategic alliances, licensing and distribution arrangements, technology agreements, supply agreements, employment agreements and commercial contracts. She also advises clients about noncompete agreements and the protection of trade secrets and other intellectual property. In addition, she counsels businesses on succession planning initiatives.

Emerging Companies
