April Couture

Operations Manager, New Futures

I worked closely with Olivia and Glen during the final days of construction on our 36-room boutique hotel. There are a lot of moving parts in the last 120 or so days of building a hotel. Within their scope, Olivia and Glen made the job seamless. Every time we decided to change something last minute, for whatever reason, they were all over it. Daystar handles everything professionally while staying calm, cool, and collected.
I look forward to working with them again on our next boutique venture.

As a provider of comprehensive IT services for our firm since 2016, Daystar continues to be an important partner for us. Aside from having strong technical expertise, their team has been professional, responsive, and easy to work with. Daystar has played a key role in keeping our small business running smoothly and securely. This relationship allows us to stay focused on our own business and our clients' needs.

Cassandra Gray

We have had a great working relationship with the Daystar team for the past several years. They are all very knowledgeable in their specific disciplines and extremely helpful when an issue arises. They break down our IT security needs for budgetary purposes in a way that everyone can understand, which makes budget approval easier. I believe Daystar will give the same personal attention to your IT needs for small businesses, municipalities, or larger corporations. They do an excellent job, and if not for them, I would have been phished many times.

Michael Bilodeau

Daystar has been an amazing IT provider for my company. I work directly with Mike and Cynthia, who are thorough, kind, and always follow through. All of their service technicians are extremely kind and care about doing a good job. I cannot recommend Daystar enough as an IT services provider.

Ashley LeBlanc

If you are looking for an IT company that is professional, courteous, responsive, and a great group of people, look no further than Daystar. We have worked with them for years and remain impressed with the service and friendliness of their employees. It feels like a partnership, not a company that only claims to partner with you. It is a company that actually partners with you. I rarely review businesses, yet I highly recommend Daystar to anyone looking for IT services in the Northeast region.
