The winner of 48 Emmy awards for my consumer investigative reporting, my reports regularly expose wrongdoing and incompetence by private industry and government agencies, and often lead to actions by law enforcement officials, as well as the enactment of legislation.

My reports, which now have a new home at PIX11, have been cited by numerous prosecutors as being instrumental in obtaining jail time for several scam artists. 

I worked as a consumer reporter for Fox 5 WNYW from 2006 to 2014, where I added more than a dozen Emmy awards to my collection, and the national newsmagazine ABC News “20/20,” from 1995 to 2003.

There, I won the National Press Club Consumer Journalism Award and the Consumer Federation of America Media Service Award. Prior to joining “20/20,” I was an investigative reporter at WCBS-TV in New York, from 1973 to 1995, where I began my highly praised Shame On You reports.

I was the senior correspondent for five one-hour Shame On You primetime specials broadcast on the CBS Television Network. I was also a regular contributor to CBS This Morning and was inducted into the National Academy of Arts and Sciences Silver Circle in 1995.

Among my notable reports are a series of exposes on toxic chemical waste dumping by Mafia-owned carting companies (my first Emmy!); the fraudulent mislabeling of high-calorie, high-fat food, which led to statewide action by the New York agricultural department; an investigation into school custodians padding their payroll with relatives, and failing to do their required work; uncovering a taxi-cab ring ripping off tourists at Grand Central Terminal; proving how Medicare and Medicaid were wasting millions of taxpayer dollars by overpaying for bandages; catching electronic stores selling used merchandise as new and confronting a Postal Service letter-carrier illegally charging welfare recipients to deliver their government checks. 

I’ve also caught jewelers on camera selling under-karrated gold; confronted auto dealers advertising specials that didn’t exist, cornered chimney sweeps who carry loose bricks and dead birds as price-gouging scams and showed how home health care attendants with violent criminal pasts were being hired and sent into the homes of vulnerable elderly citizens. 



While at ABC, I uncovered a major auto accident ring bilking insurers for millions, exposed a high-tech scam which billed added charges on consumers’ telephone bills for services they never received, and reported an undercover investigation which examined why black shoppers are often unfairly targeted by department store security personnel and salespeople as potential thieves. 

My other reports include an investigation into the forced commitment of elderly people by for-profit psychiatric hospitals that led to corrective legislation and changes in Medicare policy. My investigation into the epidemic problem of e-coli contaminated ground beef has been praised by both the Food and Drug Administration and the meat industry. 

I was born in Brooklyn, and am a Phi Beta Kappa graduate of Florida State University (go Noles!).

I received my master’s degree in journalism from the Medill School of Journalism at Northwestern University in Chicago and am happily married to my lovely wife, Shawn.
