Has anyone had any luck in contacting Dale Pitcher

Hi all : Could use your help in contacting Dale Pitcher of Intuitive Design. I have tried the work numbers and personal cell number with no luck for the past six months. I have an Essence amp which he has been unable to supply parts for a repair needed two years ago and a pair of external crossovers he has not returned for Essence subs that have set idle for the past 5 years waiting for his expertise.
