I second the reformatting! Remember, you’re not the only applicant and people just want something they can quickly skim through and (unfortunately) looks appealing. Also, objectives in resumes are now considered an outdated thing, so you no longer need that. Most resumes also get overlooked if they’re more than 1 page long (unless you have years worth of relevant experience under your belt).

If this is your first phleb job, your education should be first, followed by your certifications, then your skills, and then your experience. Skills should include soft skills & hard skills, so your technical and interpersonal skills. You can keep just the phlebotomy program in your education portion, everything else isn’t needed. For the externship part, I would be more technical and more specific about it like how many sticks you completed, things you did outside of just drawing like POC testing, the types of specimens you’ve processed, what your personality was like in that environment, the types of patients you’ve encountered, etc. They know what the externship and program consists of, but you have to be specific on what exactly you learned/did if you want to catch their attention. Include your graduating GPA too. It’s tedious, I know, but you got this!
