"Diane Koers is my computer angel. She has helped me set up and maintain our company computer software for the past 19 years. She is a joy to work with and never makes me feel inadequate for my lack of technical savvy."

Hammans Mechanical, Inc.

"When Hammans Mechanical, Inc. was established in the early 1990s, the best advice we received was to use Peachtree as our accounting program and Diane Koers as our Peachtree support.  Diane has helped us navigate through many DOS versions of Peachtree, conversions through Windows based versions of Peachtree and now the Sage versions.  Diane is a great instructor and support person.  Diane is always willing to help with the littlest issues to the more complicated and she always can resolve.  Diane is well respected in the Construction industry for her support with Peachtree/Sage.  Thank you Diane!"

"Diane was referred to us by our CPA and we have worked with Diane as a consultant regarding Peachtree and Sage software for years. Her expertise in the above programs has been a tremendous benefit to our firm. Diane has always responded quickly and has always been able to guide us through whatever issue we may encounter. I don’t know what we would do without her being a part of our team."
