Ben Cotter

Paralegal

About Ben

Ben Cotter is a paralegal with a background in litigation support, legal research, and conflict resolution. He holds a Master’s in the Study of Law from Hamline University, where he concentrated in conflict resolution, along with an ABA approved paralegal certificate and a BA in political science from the University of Minnesota.

Before joining River Valley Law, Ben worked in the rental car industry in a high-pressure airport setting. He learned to solve problems on the fly, juggle competing demands, and stay calm under stress. These skills now serve him in managing court deadlines, coordinating filings, and communicating with clients and agencies in real time.

At River Valley Law, Ben supports attorneys on civil matters involving employment disputes, probate, and property conflicts. His colleagues rely on his clear communication, responsiveness, and ability to adapt across diverse legal issues.

Outside of work, Ben has a deep interest in technology, aviation, and automotive design, especially the systems and interfaces that make complex machines intuitive to use. He has spent almost eighteen years immersed in World of Warcraft, where he explores the intersection of storytelling, mechanics, and player experience. He also analyzes film on his Letterboxd account with an eye toward structure, rhythm, and intent, approaching it the same way he approaches legal work, with curiosity, precision, and respect for how the pieces fit together.
