Great people and service. Good fit for a small business with need for a computer system, web site, and security. They have served me and my businesses very well. Much better than other services I unfortunately used before finding PCS. read more

This is a top notch IT service provider and have nothing but good things to say about them. Thank you PCS!

I am very pleased to recommend Dan Hernandez and Professional Computer Support. I have used PCS several times in different capacities, and have always been extremely pleased with the results. I purchased a computer for my business from PCS and not only was the price affordable, but Dan and his team made the entire process effortless on my part. Dan's team backed up my data and transferred everything to my newly set up computer. Even more, this process was managed so quickly that I experienced very little down time. On those occasions when I've had trouble with my computer, Professional Computer Support has provided rapid response to my inquiry. If the tech was unable to fix the issue remotely, PCS sent someone onsite within hours. For someone like me who relies heavily on my computer for my work, PCS' reliably fast response is a relief. PCS provides truly outstanding customer service. My business now provides practice management assistance to solo attorneys, and I am routinely asked whether I know "a computer guy." I don't hesitate to recommend PCS with outstanding results, especially when compared to "the guy who knows computers" that my solo attorney clients are used to. I am confident that whomever I refer will get the very best (and fastest) response and service. To anyone needing top-notch computer support, I highly recommend Dan Hernandez and Professional Computer Support. read more

Dan and his team have over 30 years' experience in all things having to do with PCs, networks, hardware, back-up systems, software, extranets - - the gambit. From the moment that Dan made his first visit to our office, I was hooked. Dan and his team quickly solved our network problems, installed an impressive back-up system that functions after midnight every day of the year, and put us on a path to security, reliabilty and dependabilty. I really like Dan all around. A state and national tennis professional, Dan has officiated at many professional tennis tournements around the country and has captained, trained and consulted to the most prestigious tennis organizations in California. He is active and connected. Contact Dan's team. They solve problems and leave all those other clowns behind. Truly exceptional and nice people! They get all our business and everyone I have referred to them is extra happy and relieved. More than a business, PCS is a religion - a way of life for better computer performance and company security. read more

This is one of the best companies in the area for comprehensive IT services. My company is a landscape architecture firm with 12 people. We first came to PCS following a brief but fairly traumatic experience with a competitor firm across the Bay. We'd looked all over to find that previous firm, but for their first task, installing our VOIP phone system, they did a terrible job at it--we were having dropped calls, spotty service, the works. They (I'm not talking about PCS, mind you) were totally mystified as to a fix. So we were shaken up a bunch, and benefited from Dan's steady demeanor and incredibly well informed employees. The team at PCS managed to diagnose what had been done wrong on our phones, and oversaw the massively complicated overhaul that followed. Our previous experience with IT consultants was with a single tech guy for a dozen or so years, and most of our equipment was aging beyond belief. Chief among them was a decade-old server, and Dan/team oversaw the replacement of the server and backups, with flawless service throughout. Anyway, call PCS: it's worth it. read more

Brian kept bragging about his company so after our computer guy went over budget and still couldn't get the server up, we gave them a try. For some reason it was complicated, something about not enough band width but they knew who to call, how to get it done and did it for what they said they would do it for. It wasn't cheap, but it certainly wasn't as expensive as doing it over and over and over. Will keep using them for our IT support. read more

What a great experience I had with Professional Computer Support located in San Francisco. I found them on YELP and called them immediately. Dan Hernandez answered the phone and immediately came out to our office to take a look at our problem. Over the next few days, Dan and his team performed a miracle on getting our network server back up and running, a true life saver! Excellent communication, very helpful and knowledgeable. I'd highly recommend Dan and his team, thanks guys! Chris, DataLOK Company read more
