Agreed I should stay overnight for endoscopy, he spoke with Dresnick - I saw him speak to him and even confirmed with a phone call at the end of his shift that Dresnick would do the scope. I was instructed to not eat or drink in the ER all night, all morning. Dresnik sent his PA, Michelle, the next morning who was cold and rude to tell me he was not doing the scope, it wasn't an emergency. His PA said he didn't even know who I was. Complete lie!!!! Then she stepped out to speak to with a nurse about Botox and a new boyfriend. I chose my health over my job when I decided to stay overnight in the ER (cancel important meetings at work) just to have my time wasted by Dresnik and his schedule.

I found a gastro with Mather, and I will never use this place again. They also REFUSE to implement a patient portal, citing its a HIPAA violation. It's NOT a HIPAA violation, because these sites are encryption protected, and a lot of medical practices use them. The portals are specifically created for the medical field. Even hospitals have patient portals.

(suite D. You know who you are.) I was waiting in line behind others trying to check in to my procedure on my phone, when I heard "MAAM" loudly and aggressively, one of the ladies at the front desk shouted pretty angrily at me to get my attention, and then demanded equally as nastily that I sign in. I don't know what would possess a person to be so weirdly rude to a total stranger just waiting in line behind others while filling out check-in as instructed. I assume they're underpaid and overworked, but that's a huge no thank you for me.

Never greets patients when they walk in, eye rolling, hangs up without saying a "thank you, or apologies". It is almost like we are interrupting her day, by coming for care.

It's an experience that took me five years to talk about because of how traumatic it was. The treatment I received by the ER staff could be compared to a horror movie. I would rather die than be treated by St. Charles again...that's the level of bad I'm talking about. I can't believe such sadistic people work in Healthcare. That's a thought that keeps me up at night. I would never say that every doctor and nurse at St. Charles is bad. I'm sure a lot of caring people work there but not the people who treated me. I know a lot of people in Healthcare and I respect them and admire the work they do but that was not my experience at St. Charles. I don't know who is responsible for hiring but they need to re think their choices! Hands down the worst experience of my 57 years on this earth. Go to St. Charles ER at your own risk. Don't say you weren't warned!
