In 2007 Kirsten graduated as a dentist at the University of Groningen (cum laude). After her graduation, she gained her experience in various private dental practices and has also been working in developing countries for various dental projects. In recent years she focussed more on implantology and minor oral surgery. Kirsten finished her PhD in April 2016 at the Oral and Maxillofacial Surgery of the University Medical Centre Groningen and she has the titel Dr. Kirsten. Since 2013 she has been registered at the NVOI as implantologist (www.nvoi.nl) and member of the Dutch quality register of dentists (Kwaliteits Register Tandartsen). Kirsten is also a member of the Academy of Breastfeeding Medicin (ABM). Based on experience with surgery in children and adults, Kirsten treats babies who have difficulty drinking or eating solid food. She thinks it's important to give babies a good start and also to help children and adults as the best as she can. Kirsten is the mother of three young sons (2014 2016, 2020) and two daughters (2018 and 2023).
