Welcome to Mobility, Messaging and More! I’m happy you’ve dropped by to visit and review my content. You’ll find virtually all of my blog posts as well as links to Podcasts that I’ve done. I’ll try to have all of my public content referenced here, or exclusively here.
If there is specific content that you are in search of, please don’t hesitate to reach out to me.
While I’ve been in the mobile messaging space for almost 25 years now, I’ve only been posting blogs articles since 2007. Many of these posts appeared on Sybase 365, SAP, and Sinch blogs. More recently, they primarily only appear here or as a LinkedIn post.

I’ve created this site to provide a single location for all of my published pieces — including some of the older pieces (prior to 2011) that are no longer online. When possible, I’ll also include links to the original or current locations, but the entire postings will also be here. I should note that, in many cases, some of the older posts may have outdated or broken links or links to other blog postings in their original locations.
Feel free to explore and please subscribe for notifications as to when new content is published.
