Dan Prendergast

Computer consulting and training


Dan Prendergast built his first computer spreadsheet with VisiCalc in 1981, and with that embarked on the path of computer consulting and training. After degrees in Mechanical Engineering and Product Design from Stanford University, and a short career designing products for Hewlett Packard, Cobe Laboratories, and RB Robot Corporation, he began teaching one-day workshops designed to instruct professionals in computer use on the work site. Those were the days of MS-DOS, Lotus 1-2-3, and WordStar. As the computer world continued to evolve, Dan moved into teaching Windows and the full suite of Microsoft Office applications (Word, Excel, PowerPoint, Access, Outlook, Project), as well as WordPerfect, Quattro Pro, SuperCalc, Harvard Graphics, and other historically interesting programs.

As class participants began to hire Dan to come to their companies to customize, apply, or further develop various software programs, the consulting part of his work was born. By 1993, Dan was building databases and setting up small networks for businesses. Over the last two decades he has helped over one hundred different clients, primarily in the Denver metro area, with database design, spreadsheet customization and automation, and with a wide range of general computer support, including computer setup and troubleshooting, networking, clearing malware, and printer installation.


Dan Prendergast can provide the following services to computer users:

Database development

With the increasing demand to keep track of more and more data, the need for better databases grows. Dan works with Microsoft Access and SQL Server to create easy-to-use and meaningful queries, forms and reports for making sense of your data.

Dan has worked with a broad range of clients including assisted living centers, manufacturing organizations, dental practices, sales operations, and more, to build new databases or to upgrade and improve existing programs. He has also created solutions that enable offices to save substantial time and effort in analyzing and reporting their data.

Computer Support

Do you have problems with your computer working correctly? Is your network or your Wi-Fi misbehaving, or do you need to have it set up in the first place? Dan can come to you to resolve those problems and/or a multitude of others.


It has been said that the computer will always do exactly what you tell it to do, not what you want it to do.

With training, Dan can teach you how to set it up to do what you want it to do. He has extensive experience teaching word processing, spreadsheets, databases, presentations, desktop publishing, and general computer knowledge.
