I have done many a headshot since the day I left photo school. It is a demand and I am more than happy to do them. I think all photographers should work on the skill to direct someone in front of the camera properly.
I don't usually put them on my site, although some are. Here is a collection of the ones I have done over the years for various companies. Some corporate, some for entrepreneurs and some for creative companies. Hit me up to shoot some heads at your company.
