What works best for me is to email directly at: firstname.lastname@example.org.
Share as much or as little as you would like and ask any questions that you need. I usually answer all emails within 24 hours. Replies do sometimes end up in your junk or spam folder so do keep an eye out for me there!
If you prefer to chat on the phone I'm always happy to set that up, I just like to make sure I am in a position to give you plenty of time and attention, so just email me and we can arrange a time with you.
