Local, hands-on, and still answering the phone.
CelluLan, Inc. has been providing IT services to clients in the greater Chicago area since the early '90s. From our base in Algonquin we manage and maintain network infrastructure and security for businesses that would rather not think about either.
You won't get a ticket queue or a different technician every time. You get people who know your network, can be on site when it matters, and tell you plainly what you need — and what you don't.
How we're different
- You talk to the people doing the work. No call center, no handoffs between strangers.
- You own your network. Equipment, passwords and documentation stay with you.
- We're close by. Based in Algonquin, we can be on site across the northwest suburbs and greater Chicago.
- Straight answers. We recommend what you need, not the most expensive thing on the shelf.
