Stellar Product Support

We have the tools you need are in our Advanced ESL & Pronunciation materials

Product Support  is  so important to us!  It’s an integral component of our relationship with trainers and instructors who use our materials  Whether in brainstorming with buyers before purchases to decide what will work best in a particular training situation or after purchase to handle problems, we move swiftly to interact personally. 

Trainers confidently choose our products, knowing that a ‘Help Line’ is available to brainstorm what clients need, to engage in Q&A on testing or training materials, and to ‘bounce’ the finer points of content and methodology. Since our inception, we have received a steady stream of accolades for how we support trainer confidence — and, ultimately, trainer success – by standing by our products.

LDS always provides fantastic customer service. The quality materials and programs available are an asset to any trainer. Thank you!


This is the order I talked with you about earlier. Kudos to you for your customer service! I’ve already been a fan of your products, but your quick response time today made a huge impression on me!
