    Always quick and easy to work with! I don’t require a lot of IT work for my business but when I do they are always quick to get me back in business without taking advantage of a small business like myself!

    I’ve experienced OTOIT both working with them and having them serve family in the area and both are positive experiences. My family felt cared for and understood.

    Best I.T. company hands down. You will not be disappointed if you go with On Top of I.T. We switched to them about a year ago and boy is the difference in service night and day. True to their name, they are always on top of all your issues that may arise. We’ve had hard drive fail on the weekends in our server and Alex called me right away and worked the weekend to bring us back up online. I’ve always gotten a response within 5 min of putting in a support ticket and they always answer their phones. They make you feel like you are very important to them and they are eager and willing to help. We’re very glad we switched to them! I’ve spoken to or worked with everyone there, all great, super friendly and just overall awesome people! If you are in need of I.T. support, you need them in your life, they make everything easier! I wouldn’t go with anyone else now that I know what superb I.T. service feels like!
