A woman who used to work at the Endoscopy Center of Southern Nevada is talking about what happened behind the scenes.

Last month officials shut down the Shadow Lane office after learning staff members reused syringes on patients, putting thousands at risk for viruses.

That employee told Action News about what she considered dangerous practices at the center.

Action News reporter Kimberly Tere spoke to the former employee exclusively.

The former employee who worked at Endoscopy Center between 2003 and 2006 did not want to be identified on television.

She gave Action News an inside look at the office that is now under public scrutiny for unsanitary and unsafe medical practices.

"We all knew something was going to happen. We just did not know when," explained the former employee.

When news broke of an investigation into unsafe practices at the Endoscopy Center of Southern Nevada, a former administrative assistant says she was not surprised.

"We did not know when it was going to happen. It was just as matter of time," explained the former employee.

The outpatient surgery center potentially exposed tens of thousands of patients to Hepatitis B, C and HIV.

The center's staff is accused of reusing syringes and vials and not properly disinfecting surgical tools.

The former employee, who Action News decided to call ' Nicole" for this story, says she did not have any contact with the syringes and viles.

She says she does not think some of the doctors at that office were even aware of what was going on.

"I do not really know if they knew that the syringes were being reused. I do not know that they knew because the anesthesiologist and the surgical techs were the ones that were putting the patients, and getting them ready and prepping them," explained the former employee.

But she says this is just one example of the center not caring about its patients.

"Surgery scheduling we were told at times to schedule up to 85 patients, 85 patients at times and you walk in that office sometimes and there would be no where to walk and patients just sitting there," said "Nicole" the former employee.

Nicole says during her time there, patients complained about doctors' poor bedside manner.

"Just very short visits with the patients, especially with Dr. Desai. That was the doctor we had the most complaints about with the patients," said the former employee.

Patients told Nicole they were tired of the crowded waiting room and over scheduling.

"Why do you think they did that? Money. Their money. It is all about money. It is what everyone felt like," said "Nicole" the former employee

Nicole says the office was not only stressful for patients, but for staff who battled the undercurrent of hostility daily.

"We were basically told you can deal with it or there's the door," said the former employee.
