Herb Greenberg is returning to TheStreet. At TheStreet, Greenberg will write a daily blog, contribute to Real Money’s “Columnist Conversation” and edit “Herb Greenberg’s Reality Check,” a subscription newsletter.

Greenberg was with TheStreet from 1998 to 2006, when he left to join Marketwatch. He then joined CNBC, and will remain a contributor there.

“We’re thrilled Herb Greenberg is returning to TheStreet,” said TheStreet’s CEO and chairman, Elisabeth DeMarse, in a statement. “No one is more passionate and does more work around companies and industries than Herb does. He sparks serious conversation to help investors separate speculation from reality by shining a spotlight on risks. Our goal is to educate investors, and help investors make money.  But avoiding losing money is just as important as making it — and nobody does it better than Herb.”

Greenberg will be based in San Diego.
