  • I have worked with Andrew since he was a lead member of the team implementing our MAS 90 software nearly 20 years ago. Since then, and through our transition to SAGE 100, I have called on him whenever we have an issue with the software, in particular when we need help solving an inventory transaction gone wrong. He is knowledgeable, experienced and thorough. He takes care to understand all the factors in a given problem before proposing the cleanest solution. His calm, kind manner also makes him an absolute pleasure to work with. I highly recommend Andrew.

  • Andrew has been a consultant for MAS 200 for our company for several years now. He has very detailed knowledge of MAS functions and MAS processes. He has helped resolve MAS issues due to the fact that he has a great understanding of how the MAS program operates. Andrew has also help us successfully upgrade several different times from older versions of MAS to newer versions which has kept us on the cutting edge of MAS technology. Andrew is very helpful and understanding with end users and takes time to listen to their questions and explain processes in terms that they can easily understand. Andrew is one of the best consultants I have ever worked with and I highly recommend him.
