Nov. 10, 1930 - July 7, 2018

It is with great joy over the life that he lived and all that he gave us, and profound sadness in our hearts in mourning our loss, that we said goodbye to our Dad after he passed into Heaven for a glorious reunion with our Mom.

At his request, we will continue to keep his website alive, and continue sharing his wealth of knowledge.
