TechInSF Consulting | IT Solutions, Computer Repair, Web Design, Digital Marketing & E-Commerce in San Francisco Bay Area

"Each time I move my home office or my actual office it's usually a nightmare. Today was the first time in over 10+ years it went perfect! My computers and printers are all networked and my VPN Tunnel is working perfect plus John reconfigured my Nighthawk Wi-Fi on the new network. Thank you so much!" "These guys are awesome!   I had a laptop problem, contacted several repair companies, no one responded, except John from TechinSF that day.  He sent Michael out for a house call the next day, who worked miracles, and provided excellent advice. Fixed the problem on the spot! I highly recommend this group for your computer needs." “John and his team did an awesome job setting up a new router and mounting WAP to the ceilings of our home. I gave TechInSF a call and John showed up the same day to assess. He worked with me to adjust costs that met my budget. Installers got the job done fast and the final product looks great. They even offered IT support after the job was done. I would definitely recommend them to anyone looking for Wi-Fi/IT needs” John Williamson and his team have provided me with technical assistance for about 5 years. In my experience he and his technicians are extremely knowledgeable and efficient.  Their response time is first rate.  I couldn't give them a higher recommendation.” I have utilized John's service both in-home and remotely on numerous occasions. He has replaced my drives on both of my laptops, dug me out of malware issues and made recommendations that have made my system extremely efficient and effective. He is professional, thorough and informed on all of the latest tech. Super responsive. John came out to my house to take a look at our wifi systems and wiring. We had been experiencing issues with connection speed for years and finally wanted to do something about it. He quoted us a pretty good price on some professional equipment, and laid out the plan. Him and his team were very professional and after the work was done we had amazing wifi throughout the house. He's been very helpful in adjusting signals following the onsite, we also used him for a number of other tech related requests. Highly recommend him to anyone.

Due to my own carelessness, I needed a security audit on my electronic devices. Since I didn’t know anyone, I googled the best consulting firm to call. TechInSf was at the top of the list! I got a callback within a half hour. I told John what happened and was advised to get a security audit. We set up an onsite appointment. Justin came over and immediately got to work on checking all of my devices. Everything (except my hard drive which he removed) was clean. Justin was professional, precise, checked and rechecked everything in a timely manner. I am so pleased and relieved with the service provided. I will spread the word that if someone needs any kind of technical support, call this company. Thank you, Justin!!

Great service, and excellent customer service! Mike is knowledgeable and tackles problems with ease. I had a broken computer and he was able to transfer data without my knowing passwords! The pickup at my home and helping to set up my computer at my home was added value. Highly recommend this company.

I've had the pleasure to deal with John on multiple occasions. He knows computers, the pitfalls people encounter, how to fix them, has practical solutions, and is a very competent and useful contact. Request John specifically. I'm sure his underlings are also skilled techies, but go to the man. He's willing to come to you home or do things remotely. His time isn't cheap, but after he's done correcting the problem, he explains what went wrong and how to avoid the same problem in the future. He doesn't get overly technical in his explanations, so most lay folk should be able to understand. If John isn't sure how to fix the problem permanently, he can temporarily remedy the problem and then refer you to someone specialized in whatever the problem is. This is the case when it comes to specific computer applications/programs. When it comes to general computer problems, John fixes them quickly. No muss, no fuss. Hope this helps.
