What our clients are saying about us

“We opened our architectural firm in 1981 and started working with Jack Moore the same year. Jack is gracious, thoughtful, and extremely knowledgeable. He has always been an active champion for our success as a business enterprise. His insight into a single section of the tax code enabled W+P to harvest almost a half million dollars in tax credits over the last several years. The quality of our experience with Jack, and everyone else at LMCW, is why we’ve never even considered changing accounting firms.”
