“John brings to bear knowledge, creativity and personal attention when he joins a process. His cornucopia of mechanical, electrical and assimilation abilities enable him to separate fact from fancy--attributes we all look for in a trusted representative.  Intrinsically scientific in his approach, he works with surgical precision and finds the clear path to every task taken. Truly a renaissance man, John has never failed to give good advice and develop multiple alternatives to reaching goals.  Quiz this gentleman on a myriad of subjects; and prepare to learn!”
