Mission: Co-marketing
is too sterile a term. SpaceFarers Corporation produces live-action technology
theater about a self-sufficient colony somewhere in space. We generate ambiance
as magical and fun as that of a great Renaissance fair, except that our action catapults
visitors and vendors into a prosperous future.
·
Vision:
World domination through immersive entertainment, creating consensus for pioneering
the high frontier as the organizing principle of mankind.
·
Tasked
with team-building, fund-raising, and B2B partnering.

Arizona municipal utility
Civil Engineer, New Area Development:
Activities range from plan reviews and hydraulic analysis using Water CAD and
InfoWater to special projects and project management.
· Managed
an interagency construction project with Pima County to bring water and sewer
service to Tucson’s new Aerospace Corridor.
· Led a
team to replace sewer and water mains in a historically sensitive area of
downtown Tucson at the site of a politically significant new hotel in what is
