You Do Not Have to Figure This Out Alone.

I am Kelly McMahon O’Brien, an attorney, tax professional, and educator who understands what it means to carry a lot on her plate. I have spent more than 20 years helping clients organize, protect, and align their wealth and legacy with their values. My approach blends expertise with empathy.

If you are the one keeping everything running, you do not have to do this part alone. I have seen what happens when plans are unclear or incomplete, and I have seen the calm that comes when everything is organized and understood.

Estate planning is not just about documents, it is about clarity, confidence, and protecting your family from unnecessary stress.  My goal is to make the process approachable, so you can focus on what matters most: living your life knowing everything is in order.

Planning with Kelly is where the education lives. If you are a Montana resident and ready for direct legal guidance, my law practice at Measure Law, P.C. is where that work happens. The two are designed to work together, so whenever you are ready, there is a natural next step.

As a fourth-generation Montanan and managing partner at Measure Law, P.C. in northwest Montana, I focus my practice on estate and tax planning, probate, business and real estate transactions. I am especially drawn to working with people navigating life’s transitions. I help people plan for the future for their loved ones, grow a family business, and manage property and legacy with intention.

If you have found your way here, you are probably already thinking about what you want to protect and who you want to protect it for. That is exactly the right place to start.
