We had an opportunity to have JDC come in to do some training with our guys that we found very informative. While we have a fairly consistent fleet of Combination Units and a HXX they all have a mind of their own. The training was very helpful when it come to getting a grip on the similarities and differences in each truck so all of our operators’ could jump in to any truck and be able to run effectively. The guys at JDC have always been great with training on new trucks, being able to help diagnose problems over the phone, or provide additional training for new employees on site.

I can’t say enough of your company’s training and the people that make it happen. It can be operation of the Vactor, maintenance and of course Ed’s wonderful nozzle training classes… We have positive feedback from our employees…

Ed is wonderful at what he does. During the year the employees pick up bad habits. The classes provide a line in the sand to get rid of bad habits. The classes give our employees time to talk to one of your employees. Your guys, if they don’t have an answer, they will get it.

The trainings now assist our organization with contact (continuing education credits) hours. The classes have proven to be well worth the money. Please keep up the good work. Thank you.

I really enjoy doing business with JDC because of the friendly staff. I deal a lot with Rob S. and Brandon M. I’ve never had a salesman that I can TRUST or depend on as much as Rob. Whenever I call either one of these guys with questions about our equipment, they always have an answer. Those guys are top notch in my opinion! I will always do as much business as possible with JDC because of the staff you have working there!!!!!!!!!! I can’t say enough good things about JDC.
