Curtis Barry has been working in Call Center Consulting for over 20 years, and specializes in direct-to-customer sales. They understand what you need to do to make sure that your phones are manned when you really need them to be.
They not only work for you, but with you, finding out what's important to you, then collaborating with you to come up with a plan of action. I thought they were a leader in order management systems, but it turns out that F. Curtis Barry & Company offer a range of services for a wide range of companies. I think you'll be surprised by what they can do for you and your company. I know I was.
