    Posted by Shaun Maloney

    Mark recently was my lawyer in a Workman's Comp hearing. I have been working with Mark for several months in preparation. At the hearing last Tuesday, June 21, 2016, Mark represented me honestly, efficiently and honorably. I would have no problem recommending Mark as I respect him as a human being and lawyer. He was always promptly at our disposal over the past few months and prepared me for the hearing. Mark is truly a gentleman and a darned good lawyer!

    Mr. Sullivan is my company's attorney and has litigated cases as they arise very successfully. He is always available to review issues as they arise. His work has helped us win suits from customers and saved us from unjustified refunds.

    Mark is an excellent attorney: professional, intelligent, thorough and perceptive. He managed our case with a clear game plan, his writing was, without exception, prompt and impeccable, with close attention to detail. Mark was always knowledgable and prepared, clearly outlining issues and options at every turn. His calm demeanor inspired great confidence throughout the legal process. Mark is so easy to work with that I plan to contact him for any legal matters that arise in the future. A smart, straight shooter and a good man.... I can recommend Mark without any hesitation whatsoever.

    Mark Sullivan is a first class lawyer. I highly recommend him! Mark successfully represented me in a Workers Compensation action, displaying dogged determination, keen anaylitic skills, a thoroughly researched knowledge of the law and confident courtroom demeaner.

    Mark did a very good job of educating me in the process. He was instrumental in getting what I needed from Wyoming Worker's Compensation. He was very knowledgeable and provided fantastic arguments.
    He contacted me when said he would and conducted himself as nothing but professional. I think his patience with me was more than exceptional. I questioned everything and he knew the answer or would find it for me. I would and have recommended his services to others.

    Our organization hired Mark Sullivan four years ago. We needed legal advice on some longstanding and ongoing issues. We were impressed with how quickly he grasped the facts and provided options. Mark did not try to rush us to litigate but rather encouraged a non court solution. Once it was clear that was not to happen, he advised us on other paths. Mark was clear about the issues, estimated the costs, length of time the effort might take and guided us with dignity and expertise through the processes. We prevailed in each case. Having Mark as our attorney gives us great peace of mind.

    Mark has served as my company’s legal counsel for the past five years. During that time he’s helped us successfully navigate a wide range of vexing legal issues including implementing our stock option plan. I find Mark exceptionally easy to work with- he’s sharp, responsive and, when necessary, hard-nosed. Perhaps even more importantly, he knows how to rein-in my sometime irrational urge for legal confrontation when it’s not in the company’s best interest. I recommend Mark without reservation.

    I can't be specific, but I hired Mark Sullivan at least three times in 5 years to help in an ongoing intellectual property dispute, which thanks to Mark is no longer "ongoing." Its over! With carefully calculated negotiations and round table toughness, Mark successfully took on a team of opposing lawyers and won for me a favorable settlement. Later he showed thorough knowledge of the law and keen resourcefulness, not only quelling opposition attacks, but also winning for me a greater reward than either of us expected. If you are looking for an attorney who knows the law, knows how to use it, and can work effectively and efficiently on your behalf, I would highly recommend Mark Sullivan.
