Instead of trying to upsell me or charge me an arm and a leg to fix it, he immediately advised me that it would not be worth my time or money to try to fix it. He suggested it's time for a new laptop. I offered to pay him for the the time he spent on diagnosing it and he refused. Even though the laptop didn't survive, from this point forward, I will be going to Alpha computers exclusively for all my electronics repairs because I know this is an honest professional business that I can trust.

A++ Highly Recommended!…read more I had an outstanding experience with Corona Print Shop, and I cannot recommend them highly enough. Lisanne was absolutely amazing. She went above and beyond to help me with what started as a relatively small print order, treating it with the same care and professionalism as if it were a major project. The finished product was beautiful, high-quality, and exceeded my expectations. A few days later, I realized I had forgotten to include several other people who had been added to my meeting. I contacted Lisanne and asked if there was any way she could accommodate a last-minute rush request. Without hesitation, she understood the situation, expedited the order, and once again delivered a beautiful finished product right on time. That level of customer service is rare today. Professional, responsive, friendly, and genuinely committed to helping their customers succeed. From now on, Corona Print Shop will be my first choice for all of my printing needs and special events--whether the project is large or small. Thank you, Lisanne, and thank you, Corona Print Shop, for your exceptional service. I look forward to working with Corona Print Shop on many future projects. Thank you again for the outstanding service! Hugo

We initially thought we were going to use Staples, and after comparing their paper selection and prices- absolutely knew we made the right choice with Alpha Graphics. I remembered calling on a Friday and speaking to Alexis who was friendly and so professional. She had our "proofs" ready in a few hours and we were able to pick up and view. We decided to make a few additions and emailed another version the following Monday and by noon everything was ready to go. Let me say- the Prayer Cards and Program were beautiful. Outside of our design , the quality of the paper used was professional- glossy, thick and exactly what we were looking for. Thank you Alpha Graphics. I appreciated that you were so easy to do business with, created a professional product, and moreover, your competitive pricing!
