They should have a VP of Sales in place instead of letting marketing teach tenured sales reps how to sell.
Every training we were required to go to was pretty much a waste of time. No company wants to know how long you've been in business, how many awards you've won nor do they want to hear about tons of stats you've made up. They want to tell you their problems and hear how your product can solve them.
Marketing wants you to talk the clients' ear off. Stop. Your style does not work.
