I don't believe he has an email address. There is not one listed on my receipt and in the few years of working with him and a few referrals, neither I nor any of my friends have contacted him by email.
I would suggest you call, 9 times out of 10 I have reached him by phone, and he is always willing to answer my stupid questions that don't bring him any additional business. Good guy to deal with, especially since it's nearing the end of the season it should be easy to get ahold of and get in with him. Regards.
