Thompson Coburn is pleased to announce that Allen Capdeboscq Jr. has joined the 430-attorney Firm as Chief Operating Officer and Trish Lilley has joined as our new Chief Marketing and Business Development Officer. These key C-Suite additions position Thompson Coburn for strategic growth and an amplified national presence in the legal services market. 

Allen joined Thompson Coburn in November 2022 after serving for more than 20 years in senior leadership roles in corporations and professional services firms, including Peabody Energy, A.G. Edwards and Shell Oil. Most recently, Allen was the Chief Financial Officer of EmpowerMe Wellness, a growth-focused integrated health care services firm. Trish joined the Firm in January 2023 and is a veteran legal marketing executive with more than 20 years of industry experience, most recently with Stroock & Stroock & Lavan LLP and Fox Rothschild LLP. Allen will be based in St. Louis while Trish will work from Thompson Coburn’s New York office, which opened in 2021 with our combination with Hahn & Hessen LLP. 

“We’re incredibly excited to welcome these two dynamic executives to our firmwide leadership team,” said Thompson Coburn Chair Roman Wuller. “Allen has successfully led teams through numerous mergers and acquisitions with a people-first mindset and a focus on strong, strategic growth. Trish is known nationally for her innovative marketing and business development approaches and her dedication to efficiency and measurable outcomes. They’re fantastic additions to our already talented C-Suite and we look forward to an exciting new era of Thompson Coburn under their leadership.” 

As the ranking administrative officer, Allen works directly with the Firm Chair on internal and external business priorities. He is a member of Thompson Coburn’s Executive and Management Committees and ex-officio to all other Firm committees. Allen is a global financial and operational leader with deep experience in strategic planning and business development, and is skilled in leading large cross-functional teams. During his career in the investment banking, energy, and health care sectors, Allen led dozens of corporate transactions totaling over $8 billion.

“I’ve worked with talented attorneys throughout my corporate career, and I’m thrilled to transition to the legal industry with a strong national firm like Thompson Coburn,” said Allen. “In the few months I’ve been with the Firm, I’ve been impressed by the talent and dedication of our administrative team and the drive of our attorneys to provide exceptional service to our clients across the country and collaborate on new business strategies.”

Trish is an award-winning chief marketing officer who leads firmwide marketing and business development programs for Thompson Coburn practice areas and attorneys. She is known nationally for her creative, highly effective approach to client development, digital innovation, content-driven branding, market-entry strategies, and marketing operations. A past president of the 1,000-member Northeast Region chapter of the Legal Marketing Association, Trish’s industry leadership in the areas of digital marketing and legal marketing innovation have earned national recognition by the New York Law Journal and the Managing Partner Forum. 

“I’m passionate about the power of strategic marketing and business development to make a true impact,” Trish said. “Impact at the individual level, for attorneys looking to expand their business opportunities; impact at the practice group level in gaining national attention and reach; and impact at the firmwide level, strengthening the Firm’s already solid reputation in the market. Thompson Coburn has a fantastic story to tell and a remarkable value proposition for clients, and I’m thrilled to collaborate with my marketing team and C-Suite colleagues to tell that story.” 

In 2022, Thompson Coburn was ranked 143rd in the AmLaw 200. The Firm earned $254 million in revenue for 2022, an 8 percent increase from 2021. The Firm completed two successful combinations during the pandemic, opening a New York office in July 2021 and a Dallas office in March 2020. Both offices have experienced steady or increasing attorney headcounts and collaborate frequently with attorneys across Thompson Coburn’s five other offices.
