Bob Landgraf Sr.

Founder / Master Plumber

Bob began the business as a sole proprietor in 1972. Along with his wife Vickie, he operated a very successful small plumbing company specializing in dental suites. Bob remained available to consult on a day to day basis since selling his share of the company to Bob Landgraf Jr. Bob had always been active in his community of Westminster and served on the Board of Education in School District #50 as well as coached and sponsored youth sports for many years. It became common knowledge that when there was a need in the community — Bob Landgraf was one of the people you went to first for help. Landgraf continues to flourish under the same principles he instilled 50 years ago.

While growing up in the business and working each break during college Bob Jr. was able to learn the business by working “alongside the boss”. In this case the “boss” was also “Dad”. Bob Jr. has helped manage Landgraf since 1987 after graduating from Regis College. In Bob Jr’s early years at Landgraf he established a service department to support residential and commercial plumbing and heating needs, that continues to flourish today. As his father famously said, “a water heater doesn’t know whether it’s a good or bad economy”. He continued to work while attending graduate classes at CU where he gained his Masters Degree in 1992. Bob Jr. purchased the company from Bob Sr. in December of 2009.
