"I have been with DDPS for about a year and a 
half, coming from a sales position at another manufacturing company. At my previous job I felt I did not have any balance while also feeling underappreciated and undervalued. That completely changed once I started here, and I wake up each day excited to go to work. I am constantly learning new things and 
I have amazing support from my manager."

- John Delserro, Aftermarket Sales Representative
