Kathy Gray
Guild Mortgage – Camarillo, CA

"Our family considers ourselves very lucky. Several years ago through a routine internet search we discovered COMPUTER WHIZ ON CALL. Since that day all our computer/printer/WiFi issues have become a thing of the past. There hasn’t been a problem within our home that Paul of Computer Whiz hasn’t been able to troubleshoot with satisfactory results. We can always rely on him to resolve myriad technical issues. You won’t have to pack up your malfunctioning device to go to the “hospital” for repair. Complete satisfaction will be rendered at your home site. Along with the highest degree of technical knowledge you can also expect, courtesy, punctuality and a willingness to explain in detail the problem that required the need for service. We remain very happy campers and now think of Paul as a family member."

Beverly Patrick
Camarillo, CA

"My HP was running extremely slow and I had many issues accessing certain programs, etc.  After months of this and a high quote from Best Buy, I just decided to just buy a MAC.  I called Paul to transfer my files and photos and also maybe teach me a little about my new MacBook Air.  He totally surpassed my expectations.  He ended up not only helping me transfer and organize my files but removed a virus, getting my HP back and running just like new.  He also recommended free workshops to learn how to use my new computer.  Such an honest and knowledgeable guy, which I’m especially grateful for because I know nothing about computers."

Domonique Rodriguez
Camarillo, CA

"I’ve know Paul for a few years and I can say that he is a genuine and honest nice guy. He knows technology inside out.  He offers great value and I could not be happier with his work…. highly recommend him, simply the best."

Debbie E.
