EfficientC Outsourcing, LLC Clients

The Heart of What We Do

Clinical and Laboratory Standards Institute (CLSI)

I enthusiastically recommend the outsourcing services of EfficientC Outsourcing, LLC. During the past five years, our team has worked directly with the CEO of EfficientC Outsourcing, LLC., on numerous projects and am confident in her ability to execute plans and provide first rate customer service.  


The company offers top-notch quality, services, and rates. Across the board, we are always pleased with their work. Every project has illustrated their attention to detail and concern for quality. Rebecca and her team manage our customer service and membership call center, live chat support, and emails. They complete monthly and weekly mailings to targeted membership groups and customers. They are also integral to our membership retention program and preform our monthly outbound calling campaigns to renewing and lapsed member. They go above and beyond to ensure they reach every member possible even if it means making extra calls to find the right person.  They always provide excellent customer service and the surveys we send to our customers show it, our customer service satisfaction rating is always in the mid 90’s.

We value EfficientC Outsourcing's creativity and knowledge and appreciate working with an organization that focuses on nonprofit organizations like ours. We see them as vital partners in our mission and I look forward to our continued partnership.
