About Me

I'm a passionate consumer lawyer, designated as the “most active consumer attorney” by the debt collection industry for five years in a row. In 2001, I graduated from the University of Pennsylvania Law School. After graduation I worked for several major firms in New York and Connecticut.  

In 2006, I started Lemberg Law. The firm has grown to 18 fult-time employees. I've helped more than 11,000 consumers recover more than $30 million for debt collector harassment, cell phone robocalls, and defective lemon vehicles.

Among others, ABC News, FOX News, MSN, Channel 7 in Boston, the Los Angeles Times, Consumer Reports, and the Boston Herald have interviewed me regarding consumer issues. 

At Lemberg Law, we are committed to fighting consumer law cases and obtaining the justice our clients deserve. If you have an issue with debt collection harassment or telephone harassment, or if you have a personal injury, lemon law, bankruptcy, auto fraud, or other consumer law issue, it’s our pledge to help you.
