This is an awesome Facebook group lead by a talented friend of mine that I recommend checking out if you are an administrative professional in Austin, TX. It's a group that is growing fast that is expanding from a once a year event to more networking options. Their Facebook page also posts links to informative articles.
The Association for Healthcare Administrative Professionals is a membership site, but there’s a great list of resources and other information geared towards admins in the healthcare arena that can be accessed without a membership.
A wonderful new blog with great tips for assistants. It's in Spanish so if that's not a language you are fluent in, simply open the site in Chrome you can use the Google Translate feature to switch it to English.
This is a wonderful blog by one of my friends that is a fantastic EA. Her articles are under the Musings & Discoveries tab and she also lists great resources under the Recommended Sites & Resources tab.
There are not only great articles but wonderful resources to help assistants stay up to date with tech, travel tips and much more. I also love the “Real Careers” section, which details interviews with administrative professionals from around the world.
This website is mainly geared towards continuing education and conferences, but they have a great blog (navigate under the "learn" tab). They also list job openings as well as local chapters you can join in the US and Canada.
The founder is a powerful champion of the PA profession and the blog on her website has insightful articles and tips geared towards assistants. She also is a guru in the arenas of social media and personal branding.
