What Clients Say About Us
Sebastian was able to determine the issues and make recommendations for solving those problems. We would most definitely recommend Sebastian to other colleges or businesses because of their well-rounded yet technical knowledge base, outstanding customer service, and continuing evolution of technology awareness.
Sebastian is one of the best companies I have worked with from a customer standpoint.
Sebastian is a well-recognized and highly recommended local company and a leader in the technology industry. Sebastian employees were all very gracious, friendly and technically competent. They were very quick to address our concerns.
Sebastian did a great job and I would use them again to run or fix fiber optic cables. Their team was very professional and did very clean work.
Karlene was a pleasure to work with and kept me updated during the entire process until the job was complete. I’ve worked with others in this industry and none compare to her experience or her professionalism!!
We are extremely appreciative and impressed not only with the work Sebastian has completed at Fresno State so far this year, but also the flexibility and commitment. We continually hear great things about Sebastian and are very excited to work with us on a new campus wide Access Point project.
