I went to City College of San Francisco for two years, did just fine, and transferred to Berkeley to finish my degree. None of my interviewers found it problematic. If you do well at both schools, most adcoms will assume that you would have done fine in your first two years at a four year university. There are some schools were CCs might not be looked upon favorably (the Ivies), but I got into a kick ass school as a proud product of a community college (UCSF). Rhiana kicked booty as well and she is off to UCLA. I know many (well a few) people who are at great medical schools who started off at a CC.
As far as LORs go...why would you not keep in touch with CC professors. Even after transfering, I maintained contact with a couple of my CC professors, of whom two wrote me letters of rec. The classes are smaller and bright students have an excellent opportunity to get to know professors.
I wouldn't worry about CC at all. If you do well when you transfer and do well on the mcat, you'll do just fine. If you have your stuff together and get into a great four year university out of high school and are able to buckle down and achieve..more power to you. I took the 'road less traveled' (partying, dropping out, traveling, etc) and the only way I could begin to rise academically was to start off at a CC. Thank goodness it worked.
I wish you the best of luck. 😀
