Patrick was recently ranked Band 1 for business intelligence and investigations professionals in the U.S. by Chambers and Partners in their 2021 Litigation Support Guide.  Chambers wrote:
Kelkar is vastly experienced in misconduct, fraud and corruption investigations, as well as being highly competent in bespoke intelligence gathering for the purposes of litigation. "When I work with Patrick I know I can trust the process will be done in a credible way, with no stone unturned, and the results will be reliable," notes a market insider. "He's gone to Quinlan to do high-level work specifically in disputes and investigations," adds another interviewee. One client is particularly effusive in their praise, saying: "Patrick Kelkar is my go-to person. He has decades of experience, has seen every difficult situation play out and is a steady hand in times of crisis. His sophistication and accessibility make him a partner rather than a service provider."
