Family Owned & Operated Since 1976
Dennis and Kimberly are the second generation of family owners at Gene Johnson Plumbing & Heating. The company started in 1976 when Gene and Valerie Johnson decided that Seattle needed an honest and reliable plumbing company. They were committed to delivering integrity and quality to each job and treated every customer with top-notch support—values that still stand today.
This commitment to honest service and quality workmanship brought a sense of pride to the entire family. Growing up, we would see our father’s big white trucks with the bold ruby letters and GJP logo driving away to help a customer. Sometimes we got to meet the people our father helped, getting a taste of what it was like to provide the kind of customer service that truly made a lasting impression on people. When we got older, we started working alongside our parents at the shop, cleaning and helping out with simple tasks.
Now, we are running the business as the second generation. The pride of ownership has become even more personal as we take responsibility for the continued success of the company. It’s no longer “Dad’s truck” but “Our truck”; no longer “Dad fixed that family’s plumbing” but “We fixed that family’s plumbing.”
