DEERFIELD BEACH, Fla - A controversial stem cell doctor has lost his license for good. At a hearing in Deerfield Beach, the Florida Board of Medicine voted unanimously to revoke Zannos Grekos' medical license.

The Bonita Springs cardiologist was accused of malpractice for not informing a patient of the risks involved in a stem cell procedure back in 2010.

That patient, Domenica Fitzgerald, later died. Her family is thankful that they can finally move on.

"When I heard the news I was very relieved. It's been a long time coming. Now my son and my daughter and my family can grieve my wife's memory and move on now," says John Fitzgerald, Domenica's husband.

Domenica had breast cancer and was having trouble walking and talking, side affects from the chemotherapy. She went to Dr. Grekos, a family friend, for a stem cell treatment. Hours after the procedure she had a bad reaction and died 11 days later.

Her family has been looking for justice ever since. "What he did was wrong and justice came about today. It was very good," says Fitzgerald.

Grekos violated an order by the State Department of Health in 2012 when another one of his patients died from a stem cell procedure.

For Domenica's family this ruling was everything they were asking for.

"That was our main goal. This has to stop, he can't hurt anyone else like he did my poor wife," says Fitzgerald.

Another hearing is schedule for June in the death of Dr. Grekos' second patient.
