Our Heritage

The Pillars History

Since founding Round Table Group in Russ Rosenzweig’s Northwestern University dorm room in 1993, he and his partners have dedicated their professional lives to helping litigators to more quickly, efficiently, and cost-effectively engage the finest expert witnesses. Over the years, they honed and refined their search techniques to such a high level of mastery and excellence that they were profiled in the Wall Street Journal, honored by the Inc. 500/5000, engaged by 100% of the Am Law 200, and acquired by Thomson Reuters.
