My sister is a photographer who introduced me to Patrick's work on Flicker. When he moved to San Francisco she connected us. On a whim I asked him to photograph my 70th birthday party, a large affair at local club, never having met him. He showed up, and spent the night capturing indelible images like a ghost. He never intruded on a moment or a person and yet gave me hundreds of photos that perfectly capture the night. This guy is an ace! Honest, prompt, and with an eye that you can't pay for. I'd use him again in a heart-beat, and wish that I had more time to hang out with him.
