William did a great job discovering what are sleep needs were by asking specific questions and listening to our responses. He is extremely knowledgeable about his industry. I am a Territory Manager and have been in sales for 27 years. William is an asset to your company and he should be recognized for his efforts to make me and my wife happy.
