Sure!  Start by putting together a list of your achievements since your last review - goals met, objectives accomplished, additional duties assumed, initiatives taken, monies collected - anything that will clearly show that you' re doing more than just what the job requires, that you' re exceeding, in other words, the expectations for this particular job.  Take two copies of your list, one for you and one for the office manager - so you' ll both be looking at the same information.  If your proposed increase is 3%, offer you list of accomplishments  to the office manager and politely ask if the amount of the increase is negotiable and see what sort of response you get.  If the increase isn' t negotiable, you may want to dust off your resume and quietly start a job search - keeping in mind that it' s always easier to find a job when you have one.  On the other hand, if the increase IS negotiable and you' re asked what sort of raise you have in mind, I' d counter with a range and say something like, "Based on what I' ve been able to accomplish, I was anticipating an increase in the 5% to 10% range," or maybe 5% to 7% range, and see what happens.  All this amounts to is basing your request on you own accomplishments, not on what you believe others have received.  Make sense?
