Prior to joining KDLM, Katherine worked for a law firm in Connecticut representing clients in complex personal injury cases. She co-tried several medical malpractice cases to verdict, all of which resulted in substantial awards to her clients. Katherine’s notable trials include an award of $25 million to a client who underwent a below-the-knee amputation due to medical negligence, and an award of $12 million to the estate of a man who died by suicide after receiving improper psychiatric care. As a result of these verdicts and others, Katherine was inducted into the Connecticut Personal Injury Hall of Fame in 2015 and named a Distinguished Leader in the Law by the Connecticut Law Tribune in 2017.
