Lisette Sier

"Working in health care is in my blood. Because I want to develop myself, I took on the challenge of working outside the hospital. THC offered me this opportunity. The service and customer orientation that the company exudes makes THC unique in the commercial healthcare sector".

Project Manager Contraception

Lisette is the primary point of contact for obstetricians and general practitioners in the region of Groningen, Friesland, Drenthe, Flevoland and Noord-Holland and for the GGD and SENSE institutions in the north of the Netherlands. She is responsible for the provision of information and service regarding T-Safe, Multi-Safe and Ballerine and the necessary instruments. 

In addition, Lisette develops accredited refresher courses, provides meetings and training for healthcare professionals. Finally, she follows developments in the gynaecological field in collaboration with healthcare professionals.


Lisette holds an MBRT degree and has almost 10 years of experience as a radiation therapist. She was mainly interested in the gynaecological area. After she was allowed to present her research at the European ESTRO congress, she was encouraged to share more information. That's why Lisette started a lifestyle blog, on which she can be a source of inspiration for the Dutch woman. This is in line with the vision of Titus Health Care: free to be who you are.
