Welcome to Diers Klinik,


My name is Liza Diers. I founded Diers Klinik in 2006, motivated by a deep belief that fertility treatment should be accessible to everyone, regardless of their background or orientation. I founded the clinic on the principles of inclusivity – a philosophy that remains at the heart of Diers Klinik‘s DNA and continues to guide our mission today.


At Diers Klinik, we are very proud of our long history in assisting a wide range of clients, including single women, lesbian couples, transgender couples and heterosexual couples to achieve their dreams of starting or growing a family.


My team and I look forward to welcoming you in the clinic – you are in the best of hands.
