Looking for a certified trainer with long experience, in the classroom and online, to offer you custom training?

We at CallahanTech feel everyone deserves to understand their technology.  After all, they bought it.  Yet most training is expensive, inconvenient, and easily forgotten. 

At CallahanTech we believe that training starts with an assessment of your needs, followed by a training plan that fits your company, and finishes with appropriate follow up processes to make certain that the lessons "stuck" and are being used in a real world environment.

Your time is important, and you should get the most out of it.  Let us help you get the most out of your time, your money, and your technology.  We are in the business of generating mastery, confidence, and increased productivity.  We ensure that you finally get the valuable training experience you, and your staff, deserve by building a custom course that fits your company's business environment; implementing that course onsite, online, or a combination of both; then following up with on-target, after-training assessment, refresher tutorials, and technical reference documents.

Prefer to hire a consultant to do the work, rather than train your staff to do it?

Then CallahanTech is also the right place to start. Our qualified experts will listen to your requirements and expectations, assess your environment, and come up with a plan that will give you what you need without breaking your budget. Specializing in SharePoint, O365 and M365 administration, Power Platform (Power Apps, Power Automate Flows, Business Flows) and other Cloud collaborative environments, we will help you with your planning, implementation, and maintenance. No business too small, no configuration too complicated.

Struggling to figure out affordable Microsoft licensing that does what you need without breaking the bank? Not sure how to organize and surface your company's data in an effective, affordable way? Do you have backups, governance, disaster recovery, or security question that the Microsoft docs don't quite address? No problem, we have a specialist on staff for those under-documented issues that will help you get the most out of your cloud implementation.

Looking for courseware or technical documentation?

One of the more frustrating aspects of technology is the lack of accurate technical information. Often, available courseware misses the mark in terms of what you truly need to learn, or white papers, docs, and articles are missing key details your company needs to have on hand for your staff. CallahanTech can write that material for you, offering you a range of options when it comes to technical material, be it white papers, technical books, or course material. From building labs, to doing the training, to writing the content, CallahanTech has you covered. Callahan is an experienced technical author and former MVP.
