Owsiak is married to Lidia Niedźwiedzka-Owsiak, the Medical Affairs Director for the WOŚP. He is also a stained glass maker, and he has qualifications in Psychotherapy.
At the age of eight, Owsiak moved with his parents from Gdańsk to Warsaw. Here, he graduated from high school with an economic profile, and later attempted to achieve a place at the Academy of Fine Arts in Warsaw. When he was a teenager, he was involved with the hippie subculture in the Warsaw Voivodeship. His fascination with this subculture led to his idea for the "Woodstock Stop", an annual rock concert held in Poland.
Due to his acquaintance with Wojciech Waglewski, Owsiak became well known in music circles. Since 1988, he has attended Voo Voo concerts. He has played at some of them with his band, Towarzystwo Przyjaciół Chińskich Ręczników, and he started his programme on the Rozgłośnia Harcerska (the Scout's Radio Station).
After the termination of his work in the Scout's Radio Station, his next undertaking was the broadcast of "Brum". He ran it in the 1991-1994 period in PR Program III. It was only broadcast on Fridays. Between 1994 and 1999, it changed its name to "Się kręci". Later, he undertook the broadcast of "Kręcioła" on Polskie Radio Program I and attended meetings with listeners on Saturday mornings at RMF FM. However, all of these broadcasts ended only after a few broadcasts, because of conflict with station authorities.
Between 1991 and 2007, Owsiak cooperated with Telewizja Polska, a public broadcasting corporation, operating throughout Poland. Since December 1991 he has been preparing a TV programme, "Róbta, co chceta, czyli rockendrollowa jazda bez trzymanki" for TVP2, which was called "Dziura w koszu" from 1994, and from 1996 "Kręcioła".
In 2007 he began working on the radio again. On 4 July 2007 he ran, for the first time, "Dźwiękoszczelny magazyn Jurka Owsiaka" on the WAWA radio station. The show was later broadcast on the Eska Rock radio station, until 4 April 2010. In 2007, he produced the youth channel, O.TV (Owsiak TV), which is available on the Direct-broadcast satellite, platform n.
Owsiak is the co-author of the "Orkiestra Klubu Pomocnych Serc, czyli monolog – wodospad Jurka Owsiaka", a book which comprises an extensive interview made by Bartłomiej Dobroczyński. He also acted in the TV soap opera "Klan" as himself and in the "Autoportret z kochanką" by Radosław Piwowarski.
At the end of the 1980s and the 1990s, Owsiak was engaged in the organization of many rock concerts. He organized a series of marathon music concerts, which all had a common feature – his characteristic "stammering" announcing, and the participation of the best Polish Punk rock bands of that time. These concerts included:Letnia zadyma w środku zimy – in Stodoła club, Warsaw – 27 January 1989 (organization debut), 1991
Zadyma na Torwarze, Warsaw 1989
50 Rock'n'Rolli Na 1 maja – in Fugazzi club, Warsaw 1992
Warsaw-Berlin 2 Step – Agrykola, Warsaw 1993
In 1991 and 1992 he ran the Jarocin Festival, along with Walter Chełstowski. They also organized the first Przystanek Woodstock in 1995 in Czymanowo near Żarnowiec.
In 1993, Owsiak founded the Great Orchestra of Christmas Charity, along with Lidia Niedźwiedzka-Owsiak and Bohdan Maruszewski, which is now one of the largest, non-government, non-profit, charities in Poland. The main objective of the charity is "Health Protection and Saving Children's Lives through Providing Medical Equipment to Public Hospitals".
His first fund-raising participation was organised spontaneously after an appeal from the cardio-surgeons from "Centrum Zdrowia Dziecka", for financial support for the purchase of medical equipment. In 1992, Owsiak invited doctors onto his programme "Brum" broadcast on Polskie Radio Program III, and repeatedly reminded his listeners on every edition about paying money into a given account. This action was also continued during the Jarocin Festival the same year.
There was a lot of positive feedback for these actions, and in March 1993, thanks to the initiative of Owsiak and Walter Chełstowski, GOCC officially came into existence and its first Great Finale was organised on January 3, 1993. Since then, the Great Finale has taken place every year and Owsiak is the main organizer and compere of the TV programme under the same title, broadcast on TVP2.
Owsiak split with from TVP after 16 years of cooperation. He ran programmes such as the annual GOCC Great Finale, "Kręcioła", "Bezpieczne Wakacje" and "Róbta co chceta". On 6 October 2007, a new channel on DTH platform n belonging to ITI Group, was launched.
The decision to split with TVP was made by Owsiak because, as he says, his programmes were not broadcast enough, and the Great Finale of this year was limited only to several five-minute-long entries.
The activity of Owsiak is often a subject of criticism. He is often accused of promoting the motto "róbta co chceta" ("do whatever you want"), which can be interpreted as an encouragement to hedonistic lifestyle and moral relativism. A subject of criticism is also Owsiak's approval of some religious associations during Woodstock Stop (for example The International Society for Krishna Consciousness) which, according to some, is a threat to teenagers.European of the year 2006
