LANWAN is an amazing company to work with! Staff at every level is not only extremely knowledgeable but also customer service oriented. I worked with LANWAN for four years and in those four years I have only known their staff to go above and beyond for their customers, and always with a warm smile on their face. LANWAN is composed of wonderful people who care deeply about helping you succeed. With their support, I was able to successfully complete various projects that ultimately resulted in increased efficiency for my organization.

I had the pleasure of working with LAN WAN during my seven years in the City of Bell Gardens. During my time working with LAN WAN I was impressed by their ability to provide clear and concise diagnosis of IT related issues; problem solve; meet all required deadlines; and provide excellent customer service. I always felt secure knowing that LAN WAN was there to assist my staff with any number of day to day issues, and that their cyber security protocols were in place to protect us from ransom ware and all other cyber attacks. I would recommend... LAN WAN's services to any other city/business, without reservation.read more

My company uses Lan Wan (Nezar Oweiss) to manage Networking, Servers, Workstations, etc. and the performance has improve a great deal. The responds on fixing any issue is short and he shows a great knowledge on the subject and work well with the staffs. He is very detail and take his time to explain and resolve the issue. I would recommend anyone with any level of IT knowledge can utilize his service.

I’ve been working with LAN WAN Enterprise for over 10 years. Before that time my network was a mess and Active Directory was badly corrupt. Today my company’s network is solid and secure.The response that I get from LAN WAN is nearly instant. 99% of the time they answer my call without having to leave a message. In the rare case when I need to leave a message, the call is returned very quickly. I can say that anyone who works with LAN WAN Enterprise is guaranteed an unbelievably quick response. Sometime problems are fixed before I... have a chance to contact an engineer. They make this possible with the use of their proactive protection tools.As far as the proficiency of the team goes, LAN WAN stands alone in the field of IT. We started out with them over a nightmare in software compatibility issues. They made sure all software protocols were being satisfied, as well as rebuilt our entire domain. The very first night they came, they stayed the whole night working until the morning. We were so happy with the job they did after working overnight; we took the team out to IHOP afterwards for breakfast. Honestly, that is the same effort we get from them every time we call them. They are not just a vendor to us; they are an extension of our team. To me personally, they feel like family.read more

Whenever I let them know that something does not require immediate attention and to go ahead and schedule their assistance, their response time is immediate, no matter how small or large the issue they resolve the problem in the most expedient manner as not to interrupt our workflow. Frankly, if we do give them a time frame, they beat it!

We have a great sense of peace knowing that we don’t have to worry about our network’s operation and security: And that is beyond value. They have allowed our company to focus on our work. When we need them, they responded quickly and completely with an expertise that is unequaled: The phone is answered each time, and emails receive a quick, priority reply immediately.

John G Most

President & CEO, Most Brand Development and Advertising

LAN WAN Enterprise has been working with us since 2004. I have always found the staff to be polite and well mannered, but more importantly, they make one feel comfortable no matter how stressful the problem is. This stems from the fact that they know what they are doing, and it shows.

Issam Elbechawati

Controller, PACWEST Security Services

They are so responsible when it comes to handling our systems, much of the time they call us and let us know about a problem before it happens. As a result it’s been years since we have had any sort of virus or malicious software on our computers. The problems we bring to them are solved so easily, that it makes us wonder if there is anything that any one of their technicians can’t do.
