I highly recommend JR Casillas of Orr McDonnell Law in Missoula. JR has represented me in a very complicated dispute involving both my general contractor and roofing company, and I couldn't be happier with his work. He has been extremely knowledgeable, responsive, and strategic throughout the process. Construction disputes can become complicated and frustrating very quickly, but JR has done an excellent job of explaining our options, protecting my interests, and keeping the process moving forward. Most importantly, I feel like JR genuinely cares about getting the best possible outcome for his clients. He has been a tremendous advocate for me throughout this process, and I would not hesitate to recommend him to anyone dealing with a construction dispute or other complex legal matter. If you're looking for an attorney who is knowledgeable, strategic, responsive, and truly committed to his clients, I would strongly recommend JR Casillas and Orr McDonnell Law.

Working with the Orr McDonnell Law firm was the best decision I made after suffering a fall. They are very professional, taking time to understand my individual situation and working with the utmost diligence to procure the result that was beneficial to me. They were timely with responding to any questions I had and explained the process of my claim, making sure I understood the entire timeline necessary to achieve the final result. I would highly recommend this firm.
Very highly recommend Orr McDonnell Law for any real estate legal issues you might have. J.R. Casillas, one of their partners, is absolutely the best. He got me a great settlement in a dispute I was involved with, and was responsive and accessible throughout the process. Probably the best attorney with whom I have ever worked. Cannot recommend him enough!
Greg, is hands down one of the most honest, loyal and downright hard working lawyers and all around person and this shows in how he cares for his clients. There was at no point during our year and half long case involving an assisted living home at which my mom sustained an injury, Greg or his para-legal Katie were not available to us as a family. They are really here for us the clients and that right there was instrumental. It allowed us the ability to not lye awake at night worrying what is going to happen next, that peace of mind was everything! Thank you Greg and Katie
I can’t recommend Greg highly enough. I’ve worked with him multiple times over the years on a range of legal matters—some of which were particularly complex—and he has consistently delivered outstanding results. His efficiency, deep knowledge of the law, and ability to navigate even the most challenging cases set him apart. He communicates clearly, stays focused on the end goal, and always makes you feel confident in the process. Every time I’ve needed strong legal representation, Greg has come through with excellent outcomes. He’s my go-to attorney and someone I fully trust.
