“All parties appreciated Mediator Maguire’s patience, insight and hard work.”

“Mike Maguire is the epitome of professionalism and civility. I’ve used him as a mediator to settle personal injury disputes over the past year. His experience working for a major insurance carrier is a definite strong suit. Mike is a real straight shooter. Of course, there are always problems with a plaintiff’s case one way or another, and I think he’s upfront about those, and he’s able to discuss that with you as a peer, having been in the trenches. But he gets to the bottom line really quick and gives you his impressions and gives you an honest read of the other side.”

“I’ve known Mike for years, and I’ve used him recently to successfully mediate a personal injury matter. He developed a reputation for fairness and honesty during his time representing clients, two character attributes he’s making good use of in his mediation practice. Because of that reputation he developed, I think his opinions are respected by both sides. And he has a warmth and sincerity to him that I think makes your clients feel comfortable, and really helps him to gain their trust, which leads to them respecting his opinions.”

“I used Mike recently to successfully settle an auto accident case. He was a formidable opponent as a trial attorney. I had some initial concerns about him having a bias toward the defense in mediation, but I quickly found while using him as a mediator that he was able to give me insight and tools and strategies to overcome the defense’s efforts to poke holes in my case that only a former defense lawyer could share with me. Thanks to that background, he really helped me overcome some of the challenges in my case, and he just knew what the defense was going to think. Because he’d worked so long with them, he understood the defense attorney and the adjuster’s language and what they needed to hear to get the case resolved.”
