I am a platelet/plasma donor at this site. I go once a month, and I have almost completely positive things to say about everyone here. I left off one star because of a phlebotomist who just doesn't seem to give a damn doing the job correctly. She has the personality of a slug and she moves a tad faster than that.
In the nine years I have been going to this center, there has been a large turnover. I think people get trained, get some experience, and then move on to better paying jobs.
Still, the act of donating blood or its components is one of the most satisfying things you can do. It takes an investment of time but the rewards are great. In addition, free cookies and gifts after the donation aren't bad, either. And, you accumulate points. I have enough points now for 15 free movie tickets. Not bad.
Go and join the blood crew who do this regularly.
