The Seibert Group is a sales consulting and writing services agency specializing in sales proposals. We show salespeople and business people how to be as persuasive on paper as they are in person. We sell our writing and training services under the Persuasion Selling™ brand name.  

Persuasion has been the subject of intensive study over the years, and this has resulted in a large body of published knowledge.  Persuasion Selling seeks to teach salespeople and sales organizations how to leverage this body of knowledge to sell more. 

To accomplish this mission, we provide our clients with consulting, writing, and educational services that show them how to produce better, more persuasive sales proposals, RFP responses, sales letters, and other sales and marketing collateral.

Voltaire said, "The surest way to become boring is to say everything." He was right, and he would have made a great sales trainer, too. To be effective in sales, you don't have to say everything, but you do have to say the right things. At The Seibert Group, we show you how.
