Sherman is knowledgeable, down to earth and very customer friendly. I was in the process of renovating my laundry room, I needed a licensed gas technician's help for my gas dryer. I called at least 5 people [not to mention all licensed tech's are super busy] but Sherman was so generous, he came by & suggested whatever was needed and quoted very reasonable price. As I was doing other renovations, he kind of suggested/recommended the code need to be followed which would help me & my family from the safety perspective. We just met twice, we talk now like we know each other from years. He is super friendly, down to earth and nice attitude.
