My best friends father has known me for about 25 years. He is a retired doctor and was professor emeritus at a medical school. He really knows a lot about me and my character. Considerably more than any professor would know. If I had him write a LOR for me would that be looked at objectively by an admissions committee? I'm going to use the pre-health advisory board at my school, but I think they include copies of all the letters they receive. I don't want to come across that it's not a deserving LOR just cause he has known me for so long. Thanks
