The best way to contact me for the first time is by filling in the contact form below. I can reply back by email. I do not publish my email address because spammers get it, too. However, if you want to send file attachments or have a long message, then you can contact me is at this email address: 
(use dashes, not underscores) but make sure that you have a subject line which will clearly differentiate your message from spam. (I will usually reply using a different address from permanent.com but the same subject, but the email address I use will depend on the topic. www.PERMANENT.com is my #1 website, but I also direct several businesses and other avocations, in addition to www.mark-prado.com.)
If you need to contact me by phone, first try me on my mobile phone. Otherwise, please call my office and if I'm not there, you can leave a message with my secretary. I run odd hours, and I normally turn off my phone when I sleep. I live in Bangkok, Thailand, which is +7 GMT, or exactly 12 hours opposite US Eastern Standard Time (except daylight savings time).
