  • My company has had issues with a collaboration room installed by others. Drew inspected the system, determined the issues and implemented a fix for a competitive price. I am very happy with his knowledge, trouble shooting and abilities. The system works perfectly now. I highly recommend him. Most importantly he’s a good honest person. Thanks!!

  • Tier One installed a sound system in our remodel project. Drew fished wire into drywalled spaces and installed 8 speakers in 4 zones. He saved us money by recommending the right products for our situation. It sounds great and we couldn't be happier. He was professional, worked hard and was a pleasure to have in our home. I would have no hesitation about referring him to friends and family.

  • Drew is reliable, timely, and kind. He heard our goals and can up with the most efficient plan. He assisted my law office in setting up a back up of our files, creating a more secure storage system, and remote access. 10/10 experience. We are so happy with the outcome.

  • As a regional property manager, I’ve had the pleasure of partnering with Tier One Technologies on several projects across multiple properties. Drew has been an exceptional partner throughout – consistently creative, insightful, and a true professional. Tier One offers a comprehensive suite of tech services, and Drew has worked closely with us to implement solutions that not only reduce utility and operational costs but also enhance the overall resident experience. From improving accommodation access to integrating advanced surveillance systems and license plate readers, Drew has delivered smart, effective solutions that have helped deter crime and improve property security. In addition to our commercial projects, Drew has also assisted with several personal home projects. He is a fantastic resource for anyone undergoing a remodel or new build. His vision and ability to blend design with technology can truly bring your space to life and help make your design everything you hoped for. His reliability, innovative approach, and commitment to quality make him an invaluable asset. I highly recommend Tier One Technologies and Drew for both commercial and residential tech needs.
