Thank you for the excellent work you did in presenting a hydraulics course to our Third Year mechanical engineers.

Your company is extremely fortunate to have such a naturally talented lecturer as yourself who understands his subject so clearly. I was very impressed by the professional manner in which you presented your material.

This is just a short note to say how much I enjoyed the course held recently at the Woodstock holiday Inn.

The fact that I entered the class not even able to read a hydraulic circuit and four days later made an attempt at designing a press circuit is a reflection on the clear concise, and professional manner that you have managed to put across what is quite a difficult subject.

Thanks for the course you presented to us earlier this year at Columbus Stainless Steel. We got positive feedback from all persons involved and already benefited from the training.

We would like to run the same in-house 4 day advanced course in August 2011. (letter shortened)

Glad to see the guys did well. After talking to both of them - they enjoyed the course and felt they learned a lot and looking forward to the next course in May.

I attended the (Name withheld) hydraulic course and was not entirely happy with the course. I’ve done some research and the feedback I get from colleagues that attended your hydraulic and advanced courses was exceptional.

Unfortunately we were unable to attend your course as you are not a registered vendor with (Name withheld) but after the feedback we have given on the (Name withheld)  course I think I will be able to persuade my company to send me on your advanced course.

Could you please send me your course dates and fees for 2011. (Letter shortened)

W. D., Engineer

Thanks Walter

The guys were very impressed with the course

Hi Walter

Thank you very much for a well presented course and the manner in which you guided and informed us!!

Your professional manner in which you tuitored us, enabled me to listen, concentrate, absorb and learn in such a way, that this resulted in me obtaining the 95%.

A colleague of mine has this book and I am finding it so useful and was hoping I could purchase a copy of “ Introduction To Hydraulics “ by Walter Zimmerman. If you would be so kind to help me out that would be fantastic!
