If clinics are short-staffed,,,where to recruit from?

I work at an out patient clinic in Mesa, AZ and we are constantly short-staffed on PCT's. When I was fortunate enough to be hired as a new grad nurse I worked the floor for 8 months as a PCT because we were so short staffed. At the time I loathed it but the techs I worked with all have about 10 years of experience each and they all had exceptional team work skills so I learned a whole lot in a very short time. I learned so much working on the floor about the machines and getting to know the patients that when I transitioned over to the nursing side it really wasn't that much of an issue.

So my question is to the charge nurses, clinical managers, and HR reps is where are you getting your new hires from? Do you use jobbing websites, staffing agencies, do you advirtise?

I've never seen an advirtisement for any dialysis clinic in any nursing magazine or had a rep come to my college where I was graduating from to let me know of dialysis opportunities. I have this perception that dialysis as a whole is missing out some great new grad nurses and techs coming out of reputable nursing and CNA programs. If outpatient clinics as a whole are short staffed in techs or nurses, where is the recruiting effort?
