Kristy is a versatile musician specializing in both early and contemporary music. She regularly performs concerts in which she presents a wide array of recorders, often in unique and surprising combinations. She is a valued member of various ensembles.

Together with lutenist Manou Schreiner, Kristy forms Duo Helia. The duo met at the Conservatorium van Amsterdam, where their shared love for early music brought them together. In this collaboration, Kristy combines her expertise on recorders with Manou's skills on the lute, theorbo, and (baroque) guitar. The duo focuses on music from the early Renaissance to the late Baroque period, and their performances are delivered with authenticity and respect for the historical context of the music. To achieve this, they use a rich variety of instruments.

Since September 2021, Kristy has been a permanent member of the recorder consort The Royal Wind Music, a unique ensemble acclaimed worldwide for the timeless beauty of the Renaissance music they perform. Founded in 1997 by Paul Leenhouts, the ensemble has since attracted a broad audience. The ensemble is based in Amsterdam and consists of eleven recorder players who specialize in the music of the Golden Age of polyphony (1520-1640). Through their authentic and lively performances, they bring this rich musical history to life in an engaging way.

Kristy also forms an innovative recorder duo with Paul Schauenburg, focusing on experimental music and new compositions. Their repertoire consists of a mix of contemporary works, improvisations, and original compositions written specifically for the duo.

Apart from her ensemble engagements, Kristy is in demand for a range of projects, including both solo and orchestral performances.

Besides her activities as a performing musician, Kristy is a professional teacher for both young and old, having obtained her Pabo diploma. She applies her knowledge and expertise in her private teaching practice in Almere and within the Collectief Muziekonderwijs Abcoude.
