I heard him speak candidly and at length at the Nasser booth, and it turns out that he was informative and generous with his time. He's got the hardcore New York, no-bullsh*t attitude and claimed that the speaker from a competing trading firm (who had a presentaion on the stage-floor and I can't remember the name of the company) was WRONG on several tax issues.
He claimed to correct the competitors' allegations on his website, within a few weeks. He was the last speaker at the marketwise school booth at the expo, and Nasser had to cut his talk short, since everyone was asked to leave the convention floor after 5PM. It was a bummer, because he had lots to say and wasn't even given a working microphone from which to speak. But he didn't care...he was screaming from the bottom of his diaphram so that everyone in the back would hear his message. It was interesting to watch him....he said that the other trading tax venues would have their traders audited with their suggestions of claiming income on Schedule C from their short-term traders (or something along those lines. Please don't quote me).
So, what happened is that instead of finishing and packing his stuff to go home after Nasser abruptly ended him...he resumed his talk for another 20 minutes on stage-right...until security kicked all of us out of the convention floor.
I would go with him. I think he did the accounting for the Datek folks, since he demonstrated something on his website that had their name on it. He mentioned that instead of Datek button being there, it would have the Nasser's name on it.
I'm confident that if David Nasser's company is working with him...he's gotta be the best out there.
The thing I liked best about his services, is that he will take your calls for FREE, if you have any questions. So, even though, he's not someone you can see tet-a-tet, I would take advantage of the free consultation phone call. It's better than having a local accountant, fail to mark-to-market your account for tax purposes. Don't know that M-t-M is, yet? Well, that's something I learned from Green.
I will use him, whenever I begin to trade.
