Bracewell Partner Becomes Shareholder in Greenberg Traurig’s Houston, New York Offices

June 5, 2025 Alexa Shrake

Kelly Robreno Koster has joined global law firm Greenberg Traurig as a shareholder in the firm’s Houston and New York Offices. She practiced for the last two years as a partner with Bracewell in both its Houston and New York offices where she focused on labor and employment law. 

Prior to joining Bracewell, Koster was a shareholder at Munsch Hardt Kopf & Harr in Houston for two years and was a partner with Eckert Seamans in New York City. 

“Greenberg Traurig’s global platform played a pivotal role in my decision to join the firm,” Koster said in a press release. “I have long respected Greenberg Traurig and its talented attorneys, and I am excited to collaborate across offices and practice groups to serve clients on both a national and international scale. The firm’s collaborative culture and extensive resources offer the ideal environment to advise clients facing complex, multijurisdictional employment challenges globally.”

Koster’s addition makes five total members of the labor and employment practice in the Houston office and 11 in New York. 

“At Greenberg Traurig, strategic growth is fundamental in our commitment to delivering exceptional service and value to clients in Texas and worldwide. We are dedicated to continually strengthening our presence in key markets to better serve our clients’ evolving needs. All clients need employment counsel and Kelly’s experience, industry insight, and client-centric approach will be invaluable assets as we further enhance our capabilities,” Richard A. Rosenbaum, Greenberg Traurig’s executive chairman, said in a press release.

Koster’s first day with the firm was June 2. 

At Greenberg Taurig, Koster will advise on compliance with federal and state employment laws, workplace accommodations, and return-to-work issues. She will also guide employers through evolving legal requirements related to non-compete agreements, religious accommodations, and workplace policies. 

Koster’s clientele will include companies in the energy, finance, health care, and infrastructure sectors.

“We are thrilled to welcome Kelly to Greenberg Traurig,” Greenberg Traurig’s Senior Vice President Shari L. Heyen and Frank Bradley, co-managing shareholders of the Houston office, said in a press release. “Kelly’s exceptional legal acumen and extensive experience advising clients across a wide range of industries set her apart in the field. Her proven ability to navigate complex employment matters will be invaluable to clients across the firm. We are confident that her addition will further strengthen our team and the comprehensive counsel we provide to employers worldwide.”

Koster is admitted to practice in Texas and New York. She earned her J.D. from American University, Washington College of Law and her B.S. from Cornell University.
