You know Gavin Buckner as the clever man with a big heart.

Right now his heart needs attention as he's having surgery. Please give what you can.

Here's what he wrote on his facebook page yesterday:

Well after finishing my 1st phase of recovery I'm told my new heartvalve has an abcess and needs to be removed and replaced

Back to UCSF for hard-core open heart surgery

I'm Robert Dobrin and here's video he and I made from Gavin's footage.
