Typically, you hire a photographer to document someone, something, or an event at a point in time.  You may want that document as a memory aid – for yourself or your family – or you may want it for promotional purposes.  Whatever your reason, if it’s important enough to you, it’s important to do it right.
There are many styles of documentary photography from formal portraits to photojournalism.  My style tends towards the more natural and spontaneous, but if you communicate what you want and why, I’ll shoot to the job.  I want you to be happy with your investment in money, time, and effort.
