I am planning on submitting my application this May/June and will have letters of rec from a science professor I am close with, a non-science professor, my research lab, and possibly my supervisor from a job I held all throughout college. I am wondering if I should wait and apply so that I can secure a letter of rec from a physician. I have 300 hrs of clinical volunteering but was unable to build a relationship with any physician because I was constantly shifting on different departments. I just interviewed for a paid clinical spot at a major hospital and am hoping I will be able to secure more clinical hours as well as relationships with the staff. Any input would be greatly appreciated!!
