Who each one suits
Pick phlebotomy if you want a short, focused program and like mastering one skill. You may work in a hospital lab, a blood donation center or an outpatient lab with early morning hours. Pick medical assisting if you like variety: rooming patients, taking histories, giving injections where allowed and handling the front desk.
Stacking them
Some people start as a phlebotomist and add medical assisting later, or the reverse. Either credential on a resume helps with the other.
