On June 1, 1950, Jakob Toller founded the Toller company based in Meilen. The company offered paving and rolling work. In addition to communities and building authorities in the area, Jakob Toller quickly gained the trust of other companies. Kurt Loher took over the company in 1983 and not only founded Toller & Loher AG, but also continued to expand the company over the years. From the beginning of 2018, Kurt Loher took a back seat. He handed over the mandate of Chairman of the Board of Directors to his son Henry Loher and the full management to Bruno Ragnacci. The latter has been with the company for over 30 years. At the end of 2020, Kurt Loher passed away after a short, serious illness. For almost 40 years he held the scepter of Toller & Loher AG. Allen appreciated his professional and human qualities. He personally hired and promoted many of our employees. We will protect his memory and continue to run the company in his spirit. On May 1, 2022, Bruno Ragnacci handed over the management to Marco Hirzel for health reasons. Bruno will continue, with his uncomplicated and natural way, as a calculator and site manager, to incorporate his specialist knowledge from his many years of professional experience. In addition, he supports Marco Hirzel with his wide-ranging experience with words and deeds.

On January 1, 1985 we founded the company DUO TOP SERVICE Ltd. The TOP SERVICE stands for our top service. The somewhat unusual name comes from the fact that we did not only offer ourselves as plumbers, but also wanted to carry out various other works. For example, our advertisement said: 'Execution of plumbing, roofing, gardening, painting, demolition and cleaning work, as well as other services'. Which was quite well received in the early years. But soon the workload as plumbers had grown to such an extent that we had to devote 100% of our time to this task. In the following time we were able to realize large and interesting projects. Also special orders like ridge turrets, weather vanes, gargoyles and ornaments are among our references. In 2016 our team doubled in size and we welcomed our two sons Mike Bussinger and Patrick Feusi, who successfully completed the foreman school in November. Shortly afterwards, Patrick Feusi decided to continue his professionalfurther education, Patrick Feusi decided to add the master school to his professional training. He was then able to successfully implement this in conjunction with a large plumbing company. To fill the gap at Duo Top-Service GmbH, we were able to recruit Pascal Bussinger to our team.He also successfully completed the foreman school at his previous employer.Now the world's largest "Duo" is looking forward to future tasks and challenges.
