Dental: While this is relatively new, there are dental offices now looking for Medical Assistants instead of, or in addition to, dental assistants.
American Red Cross: You can work as a Phlebotomist, or in Disaster Relief. If you wanted to become a CPR instructor that is another possibility as a Medical Assistant.
Phlebotomist: If you love to draw blood, working at your local blood bank, hospital, or lab would be a great opportunity. Phlebotomists generally only draw blood, and prepare samples for testing.
Dialysis Patient Care Technician: This position gives Medical Assistants the chance to work with patients on a regular schedule. They document treatment, deliver treatment, and monitor and assess patients during treatment. For someone who wants a job that gives a chance to build a lasting relationship with patients, then this is a great opportunity.
