Hi guys! I'm brand new, 2 days away from completing my dialysis technician course in DesPlaines, IL. I am preparing to take the CCHT but it is not necessary to have it before you apply for a job. I was contacted by 2 companies I applied at just because I was a CNA to train with them but chose to take this course. I was also told to wait to apply until after my certification but I didn't listen. I applied at a smaller company 2 weeks ago, got hired, & start Monday (wish me luck). I'm very excited to begin this new career, welcome all!
