What people say
Aside from being probably the most supportive colleague I have ever worked with, Sam is a knowledgeable and skilled language trainer. His lessons are always designed with a clear focus and a well-thought plan, keeping students’ needs and interests always at the forefront. As a result, students have not only a better understanding of the language being taught, but also a better idea of how to move forward with their own language development.
