About Jeffrey R.
Jeffrey R. Groendal builds his practice on steady legal training and steady courtroom experience. He earned a B.A. from the University of Southern California in 2002 and a J.D. from Pepperdine University School of Law in 2007. Those years set a foundation in both liberal arts and law that he has used throughout his career.
After law school, Groendal entered private practice and steadily advanced to partnership. He is a partner at Jeffer Mangels Butler & Mitchell LLP, where he has taken on matters that require careful legal analysis and practical problem solving. His role at the firm involves supervising cases, counseling clients, and collaborating with colleagues on strategy and trial preparation.
Groendal is licensed to practice in both California and Oregon. That dual licensure has allowed him to handle cross-jurisdictional issues and represent clients before tribunals in two states. He applies courtroom experience and negotiation skills to the matters he accepts. Colleagues describe him as methodical in preparation and direct in courtroom presentation.
Throughout his career he has balanced litigation and client advisory work. He prepares pleadings, argues motions, and participates in settlement discussions when appropriate. He also advises clients on risk management and compliance where factual and legal details intersect. He takes a practical approach to each matter, identifying discrete goals and the steps needed to reach them.
At the firm level, Groendal contributes to case planning and mentoring junior attorneys. He works on team-based matters and often coordinates between litigators and outside specialists. His experience at a mid-size firm has involved both individual case responsibility and shared firm obligations.
Outside the office he has maintained professional memberships since early in his career. Those affiliations have kept him connected to developments in the law and to peers in both California and Oregon. He combines courtroom experience, transactional insight, and a regional perspective in his work.
He is currently practicing as a partner at Jeffer Mangels Butler & Mitchell LLP and focuses on advising and representing clients in matters arising in California and Oregon.
