Ola Sendecki was born in Basel and was initially taught by Antonio Pellegrini (Pellegrini Quartet). She completed her studies at the Basel Music Academy with Alexander Van Wijnkoop (Bern String Quartet, Camerata Bern) and at the Lucerne Music Academy with Sebastian Hamann, from which she graduated with distinction. A scholarship took her to London for a year, where she studied with David Takeno and Detlef Hahn. During this time she attended master classes with Hansheinz Schneeberger, Ida Bieler, Latina Honda-Rosenberg, Guya Stiller, Ariane Matthäus and others.

Since her studies she has been very active in the chamber music scene, where she is involved in the areas of baroque, classical and jazz through to contemporary music. She is a founding member of the Kubus Quartet (2014-2020), which dealt almost exclusively with new music. Various chamber music formations in classical and contemporary music have taken her to numerous venues in Europe and overseas. She has played at the Lucerne Festival, the Yellow Lounge Berlin, the Luzern Change of Scenery, the Baden-Baden Autumn Festival and the Darmstadt and Donaueschinger Musiktage. Important collaborations with interpreters such as Uli Fussenegger (Klangforum Wien) or Graeme Jennings (Arditti Quartet), and composers such as Wolfgang Rihm or Georg Friedrich Haas, expanded her field of activity. She has also premiered solo and chamber music works by various composers. Working with the Swiss pianist Nik Bärtsch deepened her musical and chamber music intentions (Album Continuum ECM).

Since completing her studies, she has played regularly in orchestras such as the Lucerne Festival Strings, Orchestra of Europe and Camerata Schweiz. Since 2011 she has held a position at the music school in Binningen-Bottmingen. Working with young people and children is very important to her. She accompanies chamber music courses in Switzerland, Kosovo and France.
