CallahanTech was started in 2000 as a sole proprietorship to make it
easier to do custom training for large corporations, training brokers,
and companies that require sub-contract. Since then, the company has
branched out; offering training, technical writing, professional
speaking, and consulting services.
The principal expert on staff is CA Callahan, former SharePoint MVP, and certified Microsoft Technical Trainer. She has nearly 20 years of experience using, administering, teaching, and writing about Microsoft products. Although her original niche was enterprise deployment and security, over time her clients began to call on her more and more for her skills with Windows SharePoint Services, SharePoint Foundation, Search Express (which actually is SharePoint), and SharePoint Server. As the industry matured, she found that most of the emphasis from Microsoft was on Enterprise SharePoint implementations and customers, despite the vast number of non-enterprise customers depending on their products. This left an immense hole in the technical support landscape for those organizations that use the smaller of the two SharePoint products- SharePoint Services (now called SharePoint Foundation).
To pick up the slack in the information for that enormous market, CallahanTech offers support for companies who need training, documentation, or consulting on what SharePoint Foundation truly can do (see the books in the "Publication" column of this page to see that it can do enough to fill a 1000+ page book , with content to spare).

Although Microsoft has decided focus on their SharePoint Server and Cloud products by not offering a 2016 version of SharePoint Foundation, CallahanTech has not stopped supporting SPF 2013, and will do so for years to come. In the meantime, CallahanTech is working actively in the SharePoint 2016 realm, focusing on the strengths of on-premises and hybrid deployments, as well as increasingly supporting clients moving to Office 365 to pursue the improved features.
