Sam has been shooting my promotional portraits for awhile now, and there's no one else I would go to. I'm unaware of any other photographers in the area that have honed their portrait skills so intentionally.
He won't just sit you in front of a backdrop, give you a pose, snap your photo, and send you on your way.
Sam will set your expectations ahead of time, make you feel comfortable in front of a camera, meticulously tweak his lighting to make sure your photo is Time Magazine worthy, and then spend more time in post-processing than is required to make it pop and make you look like $1mil.
All that being said, you'll get the best portrait for your dollar that you can imagine.
