I am a little confused on this one. I know I need to use action verbs, but can I mix past and present tense verbs? I still work for the company, so for the duties I currently handle do I use present tense verbs (like the first line below)? For items or accomplishments that I have completed already (like the 4th bullet), I need to use past tense verbs, right? Forgive me if this is an ignorant question, but I want to make sure my resume is consistent.  Also, is it OK to mix in "responsible for" statements with the action verb statements? Thanks!
