"I have known Dorota since the late 1990's, as she worked for Testing, a distributor for the company I worked for then. We have met a number of times since at conferences in Poland, at the Silesian University of Technology in Katowice, and at courses she has organized through her company, DCOSBIM. My wife and I have even met socially with Dorota and her husband and daughter. They are wonderful people. Dorota does a superb job organizing training programs. She is an absolute delight to work with. I highly recommend her if your company has training needs. George Vander Voort"

"I have known Dorota more than 10 years and worked with her on training programs when I was employed at Buehler Ltd. Dorota is a wonderful person, always has her work organized professionally. The courses we conducted were received very well by engineers and technicians in Poland. She also interfaced with the faulty at the Silesian University of Technology for some of our programs and for conferences. It was always a delight working with Dorota. George Vander Voort"
