I could get 3 glowing rec letters from pharmacists but none from a professor. Can I still apply?

It really depends on the school. Like University of Houston, for example, requires a letter from a professor. If you don't have one, they won't even consider your application. Your best bet would be to contact the schools you are interested in applying to and asking the admissions adviser if it is absolutely necessary or not. Many times they will let you know how stringent they are with these requirements.

 

If you haven't already done so, offer the professors some sort of resume/CV. Something like "I can provide you with a CV to assist you in writing the letter". Good luck.

 

This is pretty much a good standard to do with professors since most of the time they won't know you too well as say a co-worker who works many hours beside you.

It depends on the school if they need one or just "recommend one". Having 3 recs from Pharmacists is really good and shows your pharmacy experience but it would be tough in your case if they required some from professors. I would apply to good schools that didn't require one, you'll probably have a high chance of getting in from gauging at your stats.

 

If the school doesn't require a professor the you could still apply. However, know that the lack of a professor will stand out to many interviewers. As we require "professional recommendations" but don't specify work or school related, we get a mix of both. It is pretty common to get all professors from students with only recent or no work experience. I can't think of the last application I saw without a professor at all though.

 

Rules about coursework and letters of recommendations have a tendency to be more like guidelines which fit the needs of 99% of applicants but schools are willing to overlook for the 1%. For example, many schools have a time limit on coursework, but they tend not to hold fast to that for someone who still works in the sciences. In the same way, you can ask schools for an exception due to the fact that you are too far removed from your courses. It is a reasonable request and one I could see most pharmacy schools accepting.

That being said, since your grades at a four year school are all over the map, I would highly advise securing a faculty recommendation because a glowing one might help the committee overlook some of those C's if they are led to believe that those C's are not representative of your typical work product.
