				It’s not often that I will sit down and take the time to offer a critical review, but in this case, I wanted to offer my highest endorsement of Lee Kaster and his team.



My brother passed away without a will, and I had no idea where to start the process for managing his estate. Lee was recommended by a respected colleague who had heard of Lee’s work through word-of-mouth.



I met with Lee and he explained the process for probate.  He laid out a clear and sensible timeline of what to expect throughout the myriad of actions that were required.



I can say that Lee was instrumental in settling the estate quickly and without issue.  He and his team were timely in their communications.  They filed our requests with the Court promptly; and we reached final approval even quicker than I had hoped.



It is without hesitation that I offer Lee and his team my support and endorsement for his professionalism and commitment to the estate process.

				Lee is knowledgeable, efficient, and knows what he's doing. He also kept us on track with a complicated will and trust when we (two lawyers ourselves) were a bit lost with the process. He was also extremely responsive (more so than we were with our own answers). I have recommended Lee without reservation to everyone who asks me for an estate lawyer.
