Yes, but you should be aware that having one or two letters of recommendation from science faculty or medical professionals will hold more weight and add more credibility to your application. Especially as a nontraditional applicant, it would be meaningful to have a professional in the field vouch for your ability, potential, and skills.
Additionally, some medical schools require that letters of recommendation come from specific sources, such as science faculty, school counselors, or employers. Be sure to check with the school’s application requirements to submit the requested letters as instructed.
