Entry level healthcare jobs

Hi. My son is 23 works full time at a grocery store and goes to Brightpoint for health systems sciences with an aim to become a nutritionist/dietician in a hospital or doctors office. He is looking to switch his job to gain a foot in the door at VCU or other health companies in the area. The only thing I do not believe he is interested in is elderly care. He is a dedicated worker and just needs a starting point.
