Highly recommend for Wills
Lessmann was not only extremely patient with me and the fact that my matter took a couple meetings, but he did a great job of explaining matters in a practical way, and did a great job of putting my objectives into defensible words.

Strong character and knowledge of the law
Colby was top notch to work with on our estate. Very knowledgeable on the law and helped us work through several issues with the estate and several beneficiaries. I would hire Colby again if I was in same need of an estate lawyer.
