Bio
Craig S.
Jeff is an exceptional technician, having a deep base of experience to rely upon and a keen sense of where to apply it. The number of times that he's impressed me with his deep knowledge of cPanel/Linux Web Server administration is just as high as the number of times he's helped me during our time as teammates. He was always willing to lend a helping hand where he could to members of our team. One of the most noticeable things about Jeff when I began working with him was his troubleshooting and reasoning competence. It's clear that he adds tremendous value to his organization, and I doubt that will ever change. Any team that values its commitments to customers or clients will find a dedicated partner and advocate in Mr. Zimmer.

Jeff has an incredible work ethic, and was always at the top of our daily team metrics. He enjoys keeping himself busy, and it definitely shows! When I had questions about Linux, cPanel, or anything process related, Jeff was always one of the first people I turned to. I happily recommend him for any Linux or Support role!
