The second best way to contact me is through email, with the best being face-to-face

  1. The following bold addresses are my main mailboxes, and those crossed out are deprecated ones that I cannot guarantee to check weekly.
  2. If you have an urgent need, please either contact me via phone below, or add [Urgent-SP] or [911-SP] to the subject line for my program to mark it as a priority.
  3. Emails I send might contain tracking pixels to serve as read receipt. If you don’t want to trigger that, please disable remote content loading.
  4. If you send me an email with tracking pixels or other sorts of trackers, my program might mark that as not important or even marketing spam.
  5. Please don’t send spam emails. Otherwise I’ll use a script to forward all the previous spam emails back to you.
