I like making stuff.

As a kid, my tinkering with electronics morphed into writing software in the early days of the home computer. After grad school I was an engineer making satellites including one that eventually crashed into the sun... on purpose! I worked on early mobile GPS systems but left aerospace to make bits and bytes do cool things.

For 20+ years I was in the consumer software business… mostly making games. I was president of Sierra On-Line and ran development for a bunch of other companies including Accolade, Palladium Interactive, Mindscape (later The Software Toolworks) and Spectre Technologies. I've been a board member or advisor for Irrational Games, Autoremind, Capital Entertainment Group, and public broadcaster KRCB.

Since un-retiring for the third time, I've been spending my time in the health/medical sector as the CEO of Expresso Fitness, President/CEO/Board Member of AlterG, and currently as consultant to stealth-mode startup Pulson and an advisor to Autoremind.

Just to stay nimble, I'm also writing iOs and Apple Watch software, SCUBA diving, traveling the world and building/flying drones,
