I am a pre-med freshman at a small college. This past summer I shadowed a physician and am continuing to shadow him this Christmas break. Unfortunately I won't be able to work for him this summer because of a prior engagement. For this reason I cannot say if I will ever work for him again. My question is: because I may not work with him again should I get him to write my LOR now? I have over 400+ hours of shadowing and know it will be a VERY strong recommendation.
