About me

I am a graduate of the UMKC School of Law (working as a law clerk while in school), and I graduated in the top 10% of my class in 1982.

I am the father of three grown daughters and five grandchildren. I coached my daughters softball teams when they were teenagers and they had many successes. I am an avid fan of running, and other forms of fitness which I usually do some activity every day.

    I have known Bill since opening my practice in 2006. Bill mentored me when I started off, and always proved to be very knowledgeable and helpful. Bill is an excellent lawyer with an excellent reputation among his peers.
