One of the privileges I have had in my life is the opportunity to travel extensively. I have worked in over 50 countries, visited several more and lived in the USA, China and now in France. In the covid era, clearly travel is restricted, however I use Zoom, Team and other video connections to maintain close relationships with my clients.
The most reliable and fastest way to reach me is via email at firstname.lastname@example.org. I check this many times a day regardless of location. If I am/will be off the internet, you will receive an out of office reply message, otherwise a same day or next day response should be forthcoming.
My cell phone number is via the United States +1 281 797 61 83. I will answer if possible but this service is not nearly as globally reliable as email.
If you have to mail me something, please scan and email for a prompt response. I do not use postal mail.
