I've been doing this awhile.  Well over 30 years.  I think the quality of the images speak for themselves but what you don't see is the story behind them.  As an artist, I'm never satisfied.  I always find something I would change in an image.  But when I go back through my work, sometimes years later, I find a warm satisfaction and meaning in the work I produce.  Today I may be photographing a child who's mother I photographed when they were the same age.  So many times, when speaking with clients and looking at the portraits I produced for them, they share with me the stories of the family members in the images.  Some no longer with us.  Quality portraiture is something you purchase not just for yourself, but for your children and generations to come.
