| Hired Attorney
Affirming and knowledgeable
John was knowledgeable, informative, and easy to work with while setting up my wife and I's living will and attorney of power forms. He was affirming and comfortable to work with as a same-sex couple setting up these documents to protect our family even prior to the SCOTUS ruling. He took the time needed to answer our questions and was prompt in putting the documents together once we had provided the necessary information. He was open to make the edits required and thorough in going through the final documents. We would work with him again if we had future legal needs.

He got us a judgement of $500.000
Our case involve a home builder we hired to build our "dream house." He turned out to be a thief and completely incompetent. After more than a year of fighting with the "builder" to fix the problems, we decided to try the legal route. We had never had any experience with lawyers and were not even sure how to start the process. A friend recommended John and we got an appointment the same week. He was WONDERFUL. John walked us through the process, told us what to expect (including the frustrations to come) he was very meticulous, organized, and kept us informed every step of the way. In the end he proved fraud, deceptive trade practices, and incompetence on the part of the builder. Our home was declared a complete loss and because of the fraud and deceptive trade practices,, we were awarded the full price of the house plus triple damages. The total amount of the judgement was 500,000 dollars. I hope we will never need another attorney but if we do, John is the first guy we will call. I recommend John to anyone in need of an attorney.

John Gilliam: precise, objective and very professional
I've known John Gilliam for many years. He has advised me on Montana employment law, torts--- specifically on issues of libel and slander. He has also advised me on contract re-negotiation; John helped me draft a couple of letters that re-positioned me in a dispute. His skill helped me box in a contentious party and I was able to prevail. He is able to quickly separate the emotional aspects of litigation and quickly come up with a clean, objective game plan. I would highly recomend him.

John was recommended to us by our son to help us set up our wills and other final legal documents. He was very helpful and had many suggestions that made these matters much easier to deal with. We especially appreciated his promptness also and do highly recommend him.

John is well- versed in a variety of areas and is as comfortable with motion practice and proceedings at the trial level as he is with civil appellate matters. John possesses a sharp legal intellect and a work ethic second to none. I would recommend John, without hesitation, to anyone in need of a civil attorney."

Relationship: Fellow lawyer in community
"John is an extremely talented and highly competent attorney. His attention to detail and writing ability allow him to handle the most complex civil litigation and probate cases. John goes above and beyond with his clients not just drafting wills, but ensuring that they understand the estate ramifications of the decisions they make. John excels in the area of probate and skillfully maneuvers his cases through such a daunting process with ease. From contract disputes to estate planning and everything in between, I highly recommend John."
Litigation Attorney | Jul 15
Relationship: Fellow lawyer in community
"John and I worked together and I had the opportunity to listen to him strategize and work numerous cases. When trouble found me in my own business dealings I knew from this experience to immediately turn to John. He quickly and efficiently corralled a person who was defaming me and my business. What I feared would become a multi-year battle John dispensed with in a matter of weeks. I heartily endorse this lawyer."
