Armstrong Teasdale Expands Corporate Practice with Counsel Colleen Graham

April 28, 2025 Press Releases

Armstrong Teasdale announces the addition of Counsel Colleen E. Graham to its Corporate Services practice group in Kansas City. Graham brings a wealth of experience guiding clients through every phase of the business life cycle—from launch to exit. She advises both startups and established companies on entity formation, structuring, and regulatory compliance, laying a solid legal foundation for growth and risk management.

“Our Corporate practice is a strategic priority for the firm, and Colleen’s arrival represents a significant step forward,” said Karl Riehl, Chief Talent and Practice Management Officer. “She brings a rare combination of legal acumen and business insight that will immediately benefit our clients.”

Graham’s background in financial services enhances her ability to provide sophisticated corporate counsel. She regularly drafts and negotiates commercial agreements, supports clients through mergers and acquisitions, and ensures compliance with the Hart-Scott-Rodino Antitrust Improvements Act (HSR Act) in connection with antitrust filings.

“Colleen’s experience in finance gives her a distinct edge in understanding and solving our clients’ business challenges,” said Jennifer Byrne, leader of the firm’s Corporate Services practice group. “She provides additional depth to our national corporate practice and is a tremendous addition to our team in Kansas City.  We’re thrilled to welcome her.”

Before joining Armstrong Teasdale, Graham practiced business transactions law at a well-regarded Kansas City firm. She also held finance roles at Deutsche Bank and J.P. Morgan, equipping her with a deep understanding of the financial drivers that shape corporate strategy.
