A huge thank you to all at GSM for the terrific service with my refrigerator. When our refrigerator went out we were on vacation. I trusted Stephen to come into our home and look at it. We decided that it was time to get a new one. Dan was very professional and went back to our residence to measure our space and be able to give me an estimate. Being a frugal person I did get some other estimates; however after figuring the time and cost of picking up the new refrigerator, getting rid of the old and then the install, GSM was the winning bid! Dan did an excellent job of taking great care of us. Stephen and assistant did the install in a timely manner and customer service was excellent. He showed me all the functions on the new refrigerator and answered any questions I had. Bonus he actually notify me when he was done to make sure to explain it to me. I will definitely reach out when in need of another appliance. Thank You again.

If I could give 10 out of 5 stars I would. They were very timely in getting me fit into their schedule. Super impressed with the gentleman that came out and replaced our sink and our two faucet. He did a great job installing everything and did a fantastic job cleaning up after he was done. DEFINITELY will be repeat customers! Thank you!!!!!!
