After more than 30 years in a complex civil litigation practice, Glenn E. Tremper, Esq. now serves exclusively as a neutral mediator, arbitrator, facilitator and special master. Glenn has particular experience and skill in the areas of complex commercial litigation, construction defects and disputes, estate and probate disputes, business tort disputes, professional malpractice claims, closely-held business disputes, insurance coverage and claims handling, family farm and ranch disputes, corporate and partnership separations, family business succession planning, personal Injury and other complex litigated matters. He has represented clients in commercial real estate development matters, leasing and other business management issues.
Glenn has served as a mediator over 30 litigated cases since 2015, and has represented one or more parties in over 70 separate mediations over the past 12 years. Since November of 2019, he is no longer taking on litigated matters in order that he may offer neutral and impartial dispute resolution services.
Glenn views conflict as a necessary and valuable part of human legal, business and family interactions, and maintains a firm belief that the parties and their counsel usually possess the necessary skills and experience to discuss and resolve their differences, provided the obstacles to resolution can be overcome by a skilled mediator. Each conflict is different, and a mediator employs a number of different approaches based on the parties, counsel and circumstances encountered. A good mediator is Intelligent, Knowledgeable, Persistent, Hard-working, Tenacious, Committed, Neutral, an Advocate for Realistic Thinking, Innovative and Flexible, Respectful, Patient, Understanding, Trustworthy, Empathetic, and Optimistic.
