Excellent full service A/V work and advice. Alex came to help move outlets, hide cabling, and mount an awkwardly shaped WiFi access point. He did a great job. I would highly recommend Poseidon System's service and planning hiring again for additional work in the future.

The team at Poseidon Systems are great! My new home builder left a bunch of unfinished wires for AV equipment and they were able to hook up everything and look very professional. They were on time, respectful, and cleaned up afterwards. Pricing was very good too. Highly recommend!
