Pros

I don’t think there’s any pros honestly

Cons

Everything is horrible, overwhelming environment. They make you overwork, ridiculous expectations to make 30 patients a day with all the patient challenges, meet ridiculous numbers a month , they want us to charge patients something they don’t suppose to pay, they tell us to lie the patients about the payment to get their credit card, and when they get mad because we do they say it’s our fail patient s complaints. They fire the best employees and even if they have 10-20 years either the company they don’t care they still fire them . They don’t value the employees, lack of professionalism, from every body. Bad management in every location. You can’t trust supervisors they love gossiping with the employees about other employees, if something happen to you all the locations know what happen to you . HORRIBLE! You get sick there from this toxic environment . They just care about the numbers not about you .
