Robert S. Koss, Ph.D.

Senior Trainer, Mentor and Consultant


Robert Koss is a Senior Trainer, Mentor and Consultant with Object Mentor. He spends half his time teaching courses, half his time writing and revising course materials, half his time consulting on client projects and half his time keeping up with the industry.


Robert is fluent in C++, C# and Java. He is also a self-professed Agile/XP zealot. He has seen too many clients spend "way too much time drawing UML pictures or writing use cases and never verifying any model with an executable program". His current mission in life is to get clients into code just as soon as possible and to learn to use code as a probe into analysis and design, while still managing to deliver value to their business.


Lately, he has taken an interest in dynamically-typed languages and is learning Smalltalk and Python.
