A few client reviews about our performance as a Managed Service Provider 

delivering managed IT services, and IT support to small businesses in Los Angeles


Number One in My Book

Number one in my book. Competence, thoroughness, responsiveness: When it really counts, this is where I go. I drive from Chatsworth, the far northwest corner of the valley, over Mulholland Pass on the 405 because these are the guys I trust. They are that good.

Service Provided is Outstanding

I first used ZZ computer when I had a hard drive crash in 2001. They were the only company who could retrieve the data. Since then, I have used them for both personal and office computers. At work, Ron is our IT consultant and the service he provides is outstanding! He is extremely responsive, always helpful and works with us within our budget. I’ve since recommended ZZ Computer to both friends and family and they are all pleased and grateful for the service Ron provides. I can’t recommend them highly enough!

Quality Performance

Our family has used and relied on ZZ Computer for the past two decades. We are in our 5th generation of computers sold to us for a great low price, loaded with many extras we enjoy. When a previous system bought through another vendor crashed it was ZZ that saved the day, retrieved our data successfully and built us a new unit. When our home needed a wireless environment for 5 working computers, Ron came to the house and for a nominal fee set up each unit to the router, set up our emails and printers. It has worked successfully ever since. We have bought towers and laptops and trusted their work always. In an environment of computer businesses that come and go in the market, we learned to rely on Victor, Ron and Michael to help us with all of our computer needs and they have provided quick and effective service via emails or calls when something is encountered that we don’t know how to address. We will continue to buy all our products through ZZ Computer because we can rely on their work and service. In the business world, my responsibility included getting networks and computers running and databases built for operations, so I have had to deal with many IT people. ZZ Computer people have been the most reliable and consistent in their quality performance.

I Trust No One With My Computer Except ZZ Computer

We have had some unfortunate problems with our computers at our office. However, since we learned of ZZ computer – we now have no computer problems! Thanks to ZZ Computers – I know my computer problems will be resolved, if any should come about. My experience was this…. beginning with the unique and top of the line customer service that Victor provides, to the excellent and unique technology work that Ron Zarkesh provided made the unfortunate experience a grateful one. I now can rest assure that our computers are in great hands!

I also have a home business. I can honestly say….. I trust no one with my computer except…. ZZ Computer. A very special thank you to Victor and Ron!

Very Professional

My computers, both PC and laptops have been infected by viruses at various times over the last 8 years. ZZ was able to get my comps working normal again and they did it in one day as promised. They charge extra for 1 day service but it’s worth it. They are very professional.

These guys are superb! I’ve bought a couple different computers from them over the past several years and they’ve always taken great care of me. I just bought a new machine from them and I absolutely love it. I won’t be buying from anybody else.

Fixed All Problems in Under One Hour

I got my Spotify back thanks to ZZ Computer! They just connected to my computer remotely and was able to diagnose problems and fixed them all in under one hour. It’s one of the best New Year gifts ever!

Competent, Honest, and Have Priced Their Work Fairly

I’ve used ZZ Computer for something like 20 years. They have built 3 or 4 computers for me, all of which have performed well. Most recently they repaired a computer that had gone haywire in a transition from XP to Win 7 64 bit.

In my experience, they have always been competent and honest, and have priced their work fairly. Ron has even warned me of problems before they appeared, such as a bad match of a case with a microprocessor. (He was right; the unit overheated and the whole thing had to be moved to another box.)

Reliable, Punctual, and Very Patient

Ron Zarkesh is a Genius! That’s what I always say after he has fixed our problem. Ron has built and maintained our networks and systems since we started our insurance brokerage business in 1998, and has kept us current as we have grown, moved, changed and through all our ups and downs in business. He has always been reliable, punctual and very, very patient as we have struggled to explain our problems and then follow his instructions to fix whatever our latest crisis is. He is on my mobile phone’s speed dial – and he should be on yours, too! I would recommend him highly.

Prompt, Courteous and Excellent Work

I have been a customer of ZZ Computer for over 10 years and have had my office and home computers worked on and have purchased computers from them. I have always found them to be prompt, courteous and to do excellent work. I high recommend them for your computer needs.

Work is Thorough

I’ve been using Ron Zarkesh at ZZ Computer for over seven years to solve my various computer software and hardware issues. He came highly recommended to me by a parent at our local school and in turn I have passed on the recommendation to others. He has vast knowledge in the computer field and his work is thorough, fast and his prices are more than reasonable. He is prompt in his communication, be it over the phone or email. Plus his personal manner is fantastic – always extremely pleasant to deal with and gives me great confidence he can solve my issue.

Service Excellence is Unparalleled

Ron and the staff at ZZ Computer have served all of our IT Needs for over a decade now. Their commitment to service excellence is unparalleled.

When we have ever had equipment or software problems, ZZ Computer has always been quick to respond to our needs and been able to get us back up and running in no time.
We have done three complete system and server upgrades, and ZZ Computer has gotten us back up and running with minimal disruption to our office flow.

ZZ Computer and Ron Zarkesh get my highest recommendation.

They Have Never Let Us Down

Ron and his team at ZZ Computer have been assisting our small business and personal computer needs for at least 10 years. We rely on them and they have never let us down. They are responsive, knowledgeable, and reliable and honest-characteristics that make them someone you look to and depend on. I could and have recommended them to many people and companies and will continue to do so.

ZZ Is Far Superior

My firm has worked with ZZ computer for about a decade now. We once made the mistake of using another consultant to help us with our IT needs and quickly realized that ZZ was far superior. They respond quickly to our SOS’s for help, maintain our systems and keep them free from invasive viruses, and are fairly priced. On top of that, they’re just nice people and a pleasure to work with. We’ve even given Michael access to our office and home in our absence. That’s how much we trust him. It is without reservation that I give ZZ two thumbs up.

Quick to Diagnose and Solve The Issue

We have worked with Michael and ZZ Computer since about 2005. He has been responsible for setting up and maintaining our office network. As a medical office we deal with a variety of software packages that are not your typical “off the shelf” commodity. They frequently require specialized care to make sure they operate correctly. Mike has always been able to get our programs to work smoothly and integrate our system so all of the users can remain at full functionality. Whenever we have a problem he is quick to diagnose and solve the issue either online or in person.

Speed of Response and Thorough Installation

We have been a long standing customer of ZZ computer and have had great experience with the speed of response and thorough installation and follow up with our systems. We have two locations that run together very well and ZZ Computer helped integrate our systems and keeps the company running smoothly with great systems.

Over 12 Years Now

Michael and his team have been taking care of all of our company and personal IT needs for over 12 years now. He’s managed it all from servers to the cloud, computer purchases and installations, updating all of our operational needs – PLUS resolving computer viruses and dealing with all the details of keeping all of our devices in synch. The best part is that I can count on him to get back to me within a few hours. He always does it with a smile and gives us the feeling we’re his only customer. I don’t know what we’d do without him!

Timely, Patient and Professional

Ron Zarkesh and his team have been such an essential help to my company on several occasions. Ron personally has set up my computers on 3 of my office moves in a timely, patient and professional manner. I truly believe my business has been immensely helped by his services.  He is always available to troubleshoot and, believe me, in my case that is quite frequent. And best of all he never makes me feel like a dolt when I require his help.

On top of all that he is so very, very personable with a  most easy going manner and wit. I have referred my friends to him and they have thanked me profusely.

I consider Ron the very best at what he does… quite simply a genius.
