Kathleen Flynn Peterson began her career as a registered nurse, speaking for her patients’ needs and speaking up against institutional problems that interfered with giving her patients the best possible care. Drawn to the law after serving as a juror, she continued advocating against health care injustices by focusing her law practice on representing individuals and families who experienced severe negative outcomes as a result of medical negligence.

“It is a great privilege to  have a fellow human being come to you and ask you to help them overcome what is likely the greatest obstacle they will ever face and trust you to work for them to overcome their loss, pain, grief, and despair.”   Kathleen Flynn Peterson

Her medical and legal background, along with her courtroom excellence and a deep dedication to her clients and their families, allows Kathleen to make an important difference in the lives of those she represents. She is a member in many prestigious, invitation-only trial lawyer organizations and serves as a fellow of the American College of Trial Lawyers, the American Board of Trial Attorneys, the International Society of Barristers, the International Academy of Trial Lawyers, and the American Bar Foundation.

Kathleen takes great pride in her family and considers her roles as a mother, wife, and daughter among her greatest achievements.
