Jon Kennedy was patient on the phone, explained his process and was very clear. Although Apple products are not his personal first choice, his Apple knowledge surprised me. Personally, Jon is a delightful guy, personable, friendly, upbeat and caring. We chatted a lot then discussed his process. Honestly, I was so distracted by my daughter's wedding logistics, that I didn't care how calm and laid-back Jon's approach was. (Normally, I would expect urgency and "yesterday" in my computer concerns.) Jon was communicative and positive, presenting caveats when necessary. I'm impressed that a normally PC user was so incredibly knowledgeable about Macs. Thank you, Jon, for 2 lessons. 1. I have a trusted new vendor. 2. Making me slow down and be patient with you, turned into a non-issue. I had my ancient (but working) Mac Book and access to all necessary files. The Beast is roaring and the wedding was gorgeous!

He helped me pick all the right parts tailored to my specific needs, and it wasn't a laborious process. He helped make it pretty easy. He also managed to get my system put together for less than my budget, which I very much appreciated. All in all, a great experience.

I brought my $3,000 laptop in to have the fan replaced because a bearing had begun rubbing and making noise. I even got them the replacement part, I just needed them to install it. I was told it would take a week, which I understood. After 1 week they called me and said I could pick it up. I picked it up, and when I got home I turned it on. Upon turning it on I was met with BIOS error codes and the computer refusing to bypass them to "conserve the health of the hardware." I brought it back, and told them what was happening. They quoted me another week for diagnostics, which I agreed to. After a week they told me it was my battery and that it would need to be replaced. After ANOTHER week (3 weeks since initial drop off now), they called me again and said it was ready to pick up. I picked it up, brought it home, and it was still completely destroyed. More BIOS errors, the computer running extremely slow, and it turned off instantly if it became disconnected from the charger. I brought it back once more and was met with someone telling me "well you can still use it like a desktop, just always have it plugged in." After they took it again, quoted me another week, etc etc, they told me it was my CPU that was fried and that I could pick up my computer whenever, but that it wouldn't turn on. Keep in mind I initially dropped it off for a FAN replacement. After a strongly worded phone call, threats of a civil suit, and twisting their arm, they agreed to replace the parts THEY broke but that it would take a significant amount of time. 3 months after this call, I get my computer back and it works. Since then I have experienced nothing but issues with my computer. The fan has begun violently shaking the computer, keys are pressed in and will double type (or not type at all), and the AC charging adapter has become intermittent. I wouldn't trust these people to replace TV remote batteries. Take your business elsewhere.

He also went above and beyond by helping me set up the best backup solution to keep my data safe for the future. Charles is knowledgeable, reliable, and genuinely cares about his clients.

(PICS INCLUDED)…read more TLDR: he took my solid state drive and won't give it back. ghosting my texts and calls since May 14th, 2024 in beginning of May 2024, i contacted (i believe his name is Charles, older fellow, i believe uses a cane) Main Street Computers to save my solid state drive that was recently damaged. Promised he was the best in the area on this service, even gloated it's his specialty. Told me to drive to his house in Sebastopol/Graton and drop the solid state off. Interaction was a little weird (social skills and ques wise) but he was confident and promised me he would be done within the week. I also gave him an external hard drive to use in case he needed more space for the recovery. Calls me two days later and says he's done. I got to his house, invited me in, and inside he handed me the invoice; however, as i was about to sign. i realized he didn't recover the files on my computer, but the 3 videos saved on the external hard drive and just slapped them into the computer... -_- I told him and he was not happy. i then realized - inside his kitchen and dining area - he had a set up of 3 cameras all around the space. one at the end of the dining area, one in the kitchen, one at the end of the living space (kind of down the hall). he exclaimed, "F*ck, Dammit", then promised me he'd do it right this time within the next couple days. the next day he calls me to return with my laptop as the solid state was encrypted. i arrived at 9:17 pm. i knocked on the door a couple times, heard some arguing upstairs so i waited on the porch. I then called him and then he said he'd come downstairs. i then hear some running, a couple second go by, and then i heard him coming down the stairs inside. He takes a brisk look at me, he looked a bit confused. out of it. he then takes 2 steps towards me and FALLS AGAINST THE WALL!!! I then thought he could've been drunk or on some something(?) I thought maybe i should go inside and pick him up, but i felt a weird energy and felt very skeptical, so i yelled through the door if he was okay. he just laid there. i then noticed the cameras outside on the porch too. this whole thing felt so on purpose. flight or flight came on so i ran back to my car. i looked behind me as i drove away and noticed a different man had ran outside, standing and watching me drive away, right where i stood. i drove to a lit gas station, gathered myself, and texted him if he was okay. he said "yes just hurt like hell." i couldn't shake off the thought that this was an attempted kidnapping or robbery. felt very much like a set up. to this day, he won't respond to any calls or texts. he also still has my solid state drive... thinking of getting the police involved. honestly i'm DEVASTED. I had very important files for my business and client's projects in that solid state. i was young when i started this business and did not know to back up files to an external. i then lost those clients, as well as all my personal files. an absolute NIGHTMARE

I had a truly incredible experience working with Tejas. From the moment I reached out he was…read moreprompt in replies. Don't let the age of these young entrepreneurs fool you. The level of computer expertise and customer service was far superior to any other IT type service I have ever had. I had reached out for assistance fixing my son's computer in time for Christmas. I didn't even know what the problem was. Tejas was extremely quick with diagnostics and the price was so reasonable. I was informed of each step of the repair and given different options. Communications were clear, concise and I knew what was happening to my computer the entire time. The repair was done quickly and the return made me feel safe during Covid. Unfortunately a new issue popped up shortly after Christmas. Tejas made a house call to see what exactly was happening in our own environment. Again he made a quick diagnosis. He took the computer and the only thing I paid for were the parts. I am sure this was a new issue but he would not take any additional money. Again, had the computer back in a very short time. I forgot to add both times I was texting non-stop with tons of questions. He was very patient and professional in his replies and never seemed to busy to respond or make me feel like my questions were unreasonable. Such a fine young man and I am sure his business partner he was consulting with is too. I will definitely look to to Katalyst Builds and Repairs with any future issues, whether it be personal or for my business, and I suggest you do too. Thanks again!
