“I have been a dealer for Diamond C since 2016. After carrying many other competing brands in the past 5 years, Diamond C was a true godsend. From the innovations in their products, more competitive pricing, and most of all the level of character that they conduct themselves as a company have been second to none! It’s been fun growing with them and I look forward to the future as people continue to see the value of owning a Diamond C!”
