Granite Mafia (GM) in Medford, Oregon has a large countertop selection. We walked the yard of granite slabs and purchased two of Celeste Azul.Good price and excellent installation, but the problem was removing my old tile, nevertheless GM referred the demolition by Kevin King, Lost Ark Construction.I had a positive experience, we made our selection, set dates, the demolition man, Kevin came first, measurements were taken after the demolition, then the installers, who really did an amazing job in short time getting my slabs laid, backsplash placed and my huge kitchen sink installed with the view window.It is gorgeous! Everything went smoothly. I had my reservations at first because my kitchen is older, but they did a great job. I give them five stars.

My husband Casey and I worked with Becky to pick out granite for 2 bathrooms and a kitchen with lots of countertops in our new home. Even though we were really picky and took forever she was very patient with us. We did have an issue, I myself, was not kind at all in the first review I wrote, I did apologize, but I know it was an affront to Becky. Nevertheless, she treated us with respect and kindness. We reached a very good result and I feel like things are resolved very well. She definitely took the high road in a situation where she could have refused to even deal with us. That is an example of a real class act! If I could give more stars, I would! Love this place!We would recommend this company to anyone! The granite looks absolutely gorgeous in our home !!

We got new countertops from them recently and they did an awesome job. They took out our old ones and installed our new ones while we were at work and other than the new counters you would never had known they were here. They left the workspace spotless and did a great job. We spent time doing price shopping and they were the best deal around as well. Highly recommend

Omg! I love working with Cornerstone Granite and Granite Mafia! I am working on the fourth project with them and it can’t be easier. I pick out the countertop material, drop off my sink and faucet selections and in no time my project is complete!

I have used Granite Mafia for all my kitchen and bathroom countertops. Everything from the measuring of my countertops all the way to the installation was great. I have used them 10+ times over the past 5 years for my home and my rentals and other investment properties. They are always on time and the workmanship is amazing. I will continue to use only them as the quality of each job really is the best.
