I have run a small non profit for the past 20 years and Mel has been my accountant for the last 13 of those years. Mel is very insightful. I don't know all of the accounting lingo and tax jargon. As problems arise, as they do in any business, I can call Mel and before I can get two or three words out of my mouth, he already knows what I'm referring to and is answering my question.
About 10 years back, I started getting delinquent notices on my federal tax payments. I went to Mel about the problem. He immediately theorized that the IRS had open up a duplicate account and was applying payments to a second account (under business acronym vs. business name). He called the IRS and sure enough Mel was correct!
Bottom line ... Mel always knows the answer. There isn't any of this ... "let me take a look at it and I'll get back to you" stuff. Mel figures out your problems, right then and right there, and most of the time in a matter of moments.
