    Wade, perhaps he doesn’t fit a precise definition or category but I think it would be remiss to not include Paul Sonnier … Catalyst, social entrepreneur, voice of #digitalhealth and certainly “sought” or followed by almost all of this list in some form or fashion

    • http://www.xconomy.com/san-francisco Wade Roush

      Hi Kim. Thanks for your comment. The “Top 50″ list wasn’t generated by me or Xconomy — it’s from Rock Health, Goldman Sachs, Silicon Valley Bank, and Fenwick & West. As Micahael Esquivel from Fenwick told me, there are obviously more than 50 people who made an impact the field in 2013. But as for why Paul Sonnier specifically didn’t make the list, you’ll have to ask them.

      • Kim E Whittemore

        Thanks Wade, yes of course you are the author!!! It was early and I was pre-cafffeinated. Thanks for all you do! I’m a big fan and you are a “must read” for me!!

  • Matthew Holt

    Which is why lists like this are crap!
