I am a life-long student of entrepreneurship, son of two entrepreneurs, a recovering engineer and VC, a 3x CEO, and a 2x Founder. I grew up on a hog farm in southern Indiana in a 100% wood-heated house: Hard, meaningful work has been part of my life since the beginning.

Since college, I've sought big challenges in the most exciting, volatile and difficult industries.

* Semiconductor capital equipment when there were still dozens of players.
* Consumer internet when anything was possible.
* Budget internet service, SMB enterprise software, outsourced Indian software, and even retail car sales when you could fire a canon in downtown SF without hitting a soul.
* Medical device VC investing while I got my grad degree.
* Wicked fast analog chips for digital media and lighting applications when the required performance via silicon CMOS was still science fiction.
* Solar thermal before (and briefly after) fracking and horizontal drilling cut legacy fuel prices by 70%.
* Impact entrepreneurship finance when everyone was trying to figure out the rules.
* Advising, mentoring and volunteering for dozens of Colorado businesses whenever I can find time.

I've raised money on Sand Hill Road, from friends and family, from venture debt providers, and from the government. I've successfully invested as a VC and unsuccessfully as an angel. I've thrown hundreds of pitches in the trash, and I have been told "no" by more VCs than I care to count on a couple of doomed deals.

All of the lessons of my 19-year career inform Valid Evaluation's mission and the value we are adding to entrepreneurs' businesses and to those whose organizations evaluate entrepreneurs.
