ST. LOUIS, Mo. – Armstrong Teasdale, a law firm with offices across the United States, proudly announces the addition of Robert J. Estep and Abby Zeller to its St. Louis office. Estep joins the firm as an associate in the Corporate Services practice group and Zeller joins as an associate in the Intellectual Property practice group.

Estep advises clients on general corporate law, primarily in the healthcare and life sciences industries. In his practice, he counsels clients in response to legal and business challenges and opportunities in the rapidly evolving U.S. health care system.

As a former assistant attorney general, Estep has significant experience prosecuting matters in Missouri Circuit Courts involving health care providers, including physicians, dentists, hospitals, nursing homes, pharmacists and personal care providers.

His deep understanding of investigations and prosecution enables Estep to provide a unique perspective on everything from compliance and regulatory standards to operational and management issues.

He is admitted to practice law in Missouri.

Zeller focuses on intellectual property prosecution and enforcement.

Zeller has also represented clients in opposition and cancellation proceedings before the Trademark Trial and Appeal Board (TTAB) at the USPTO.

Her background in the fashion and design industry lends well to her counsel of both Fortune 500 and startup brands navigating trademark law. Her experience also extends to advising nonprofits.
