Susan Zeller Dunn Attorney in Cincinnati

A professional journey


Sarah is a student at the University of Cincinnati where she is pursuing a certificate in Paralegal Studies and a Bachelor of Science in Mathematics. Her plan is to attend law school upon completion of her undergraduate studies. Sarah is Susan's "right hand."




"I became a lawyer to serve...to protect individuals, families and their family businesses. I have always wanted to make the law accessible...to serve as both a translator for complex provisions and a creative interpreter finding new ways that traditional legal principles can be applied to my clients’ current circumstances. To be a good lawyer, you have to be an avid reader, part detective, teacher, story teller and coach. I work every day developing these skills.”


- SZDunn
