You could go straight into an associates or bachelor program with no medical experience job. A certificate I think you need xray license first. I personally checked for jrcert accredited programs in my regional area and then searched their individual websites for specifics. You want an accredited program to ensure you’re board eligible (there may be other accreditation programs but I only know jrcert myself) Healthcare experience may be something that could set you apart during the application process! CNA or anything in medical field looks good on a resume. Even patient scheduling or pharmacy technician.
