I'm already getting letters from 2 science profs, 1 non-science, and 1 scientist that I did summer research with. I work at a nonprofit dental center and am planning to ask one of the dentists also, but can't decide which! dentist 1- has known me since august, and we get along great. we both are pretty social justice minded so I'm sure she could speak of my character and ambitions well. numero 2- has worked at our clinic since january, and I'm not sure she could write as strong of a rec, BUT I've gotten to assist her on multiple occasions. And she keeps offering to write me a letter, and say what a great job I did assisting, etc etc. it would definitely be a positive rec but I'm afraid not as strong. any advice appreciated, thanks!!!
