Chris Humphres | Co-Founder & CTO

Chris Humphres | Windsor Circle
Chris is the evil mastermind behind the technical operations here at Windsor Circle, except for one minor difference - he's not evil. It's a big technical challenge that he's leading our team to solve, but it's not his first rodeo, as the saying goes. 13 years ago, he joined a start-up called LSSi Data as one of the first employees, and rose to become VP of Research & Development before the venture-backed company was sold for more than $70M in 2007. Pair that with some PhD work at Duke, plus BS and MS degrees from the University of Alabama, and it's needless to say that Chris is the man for the job.

When not at Windsor Circle, Chris's hobbies are Alabama football, Alabama football (not a typo) and Alabama football (still not a typo).

There are a number of parking decks around the area. Valet at 21C or the Corcoran Parking Deck are a quick walk to the office.

Street parking is decently easy to find, and most of it is one hour parking.  You can generally find two hour street parking if you park on "the loop."  Consider yourself forewarned that Durham's Finest is pretty proficient with the parking tickets ($20).
