Definately get something to that effect put in your CV
people who read CVs just skim them because they get 100s per day
When i skim read yours i read it as you having had that job since you left uni.
I'd make the actual dates you did stuff stand out more, id up them a size and maybe bold them too.
Then in your bit about your job, explain it was taken as a part time job to help fund you through college / uni. Because it said 2005 - present i immedately assumed it was full time and you did it after education. Definately mention it was only part time in there somehow
People wont tell you when they mis read your CV. they will just skim it, mis read it, make an assumption then bin it and move onto the next
The key thing with a CV is to make the key details stand out (like your dates etc..) so that it can be easily skim read without them making wrong assessments.
trfidis grammar advice looks usefull too, but i'm hopless at that so my CV was checked by somebody else too lol
Trust me your e-mail address if you want and i'll send you copy of mine so you've got something to reference with.
