-Angela R., Star Accounting

"Back in 2021, we upgraded to fiber throughout the fairgrounds. At the time, we had a alternate company doing our IT maintenance and upkeep. A company named EnFocus helped us get everything set up and partnered us with QuantaSi to manage the health and maintenance of the devices. I was very impressed with their professionalism, knowledge and sense of urgency when we had a problem. Over the next two years they helped us troubleshoot problems and worked out all of the kinks of our new network. In May of 2022, our contract with the other company was up. I spoke to Nick Hahaj from QuantaSi about taking over all of our IT needs. They have done an amazing job helping us upgrade obsolete equipment to make our network more efficient. I would recommend QuantaSi to anyone in need of their services. "
