Amy Collignon Gunn

Gunn | Slater Founding Partner. Trial Attorney.

Amy has dedicated her legal career to advocating for clients and their families after their lives have been devastated by the careless and/or reckless conduct of a doctor, hospital or corporation. Whether you have been injured due to a doctor’s or hospital’s medical negligence or a corporation’s decision to sell a defective product, Amy has the expertise and insight to help. She takes her job as “counselor” very seriously, taking time to listen to each of her client’s cases. Amy guides individuals through complex litigation and legal proceedings, leading them to a resolution of the case and enabling them to return to their lives, ready to move forward.

Amy is a member of numerous state and national professional associations and organizations and has served as an adjunct professor of law at the Washington University School of Law since 2001 and is regularly asked to give presentations to her fellow attorneys on legal and ethical topics. She has received the highest ethical and professional rating of AV Preeminent® from Martindale-Hubbell® and is on the executive committee of the Missouri Association of Trial Attorneys where she works hard to ensure that our civil justice system provides equal access to injured individuals.
