How can I get experience in areas such as Case Management, Utilization Review, Health Educator Dialysis and/or Home Health?

Look for careers with insurance companies but be sure to do some research on the environment you'll be entering. Stay away from CVS Health, ie Aetna. They are not employee friendly and work life balance virtually non existent.

If you work in a hospital… you can request a transfer into case management as long as there are positions open. If not, as long as you have some floor experience and the hospital/company is willing to train they will take you on :)
