About CallahanTech

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 over 20 years of experience using, administering, teaching, and writing about Microsoft products. Although her original niche was enterprise deployment and security, then SharePoint Server, Windows SharePoint Services, and SharePoint Foundation, times changed, and now, in response to requests of her clients, she spends most of her time in the cloud, and a fair amount of time in VR.

The subscription model that the industry has moved to, can be very expensive for small to medium businesses and non-profits. CallahanTech specializes, as always, in trying to help customers do business in the most economical way possible. An example of which is getting the very most out of their subscriptions and licenses, particularly in terms of F1 and F3 subscriptions for frontline workers.

New Directions 

Thanks to the pandemic, decentralized, remote work has become ubiquitous, and CallahanTech has been focusing on training, writing, and consulting that supports clients in the Cloud. With a range of offerings for the savvy customer that includes M365 and Google Workplace, Zoho, Airtable, Power Platform, and more, CallahanTech strives to give those customers the most bang for the buck. In addition, as on-camera meetings, and isolation fatigue grows for connection starved workers, CallahanTech is offering training for business users to explore virtual workspaces, classrooms, meetings, and more in VR.

Further, as Microsoft downgrades their on-premises server offerings, Linux servers are becoming more and more a reality on the ground, as well as managing lighter user devices, such as chromebooks and tablets in a work from home world.
