Drs. Koen van Maren is a cosmetic doctor at The Body Clinic in Duiven and Amsterdam-Zuid. With his background in surgery, he works with precision and an eye for detail. He aims for subtle, natural results in which you still recognise yourself.

Biography

Koen van Maren studied Medicine at Radboud University in Nijmegen. After graduating, he gained broad clinical experience in general surgery, where precision, attention to detail and safe practice are key. He now works as a cosmetic doctor and combines his work in aesthetic medicine with his training as a general practitioner. This allows him to look at every client with both a medical and an aesthetic eye.

Fresh and confident

Koen believes that a fresh, rested appearance starts with subtle improvements that suit your natural facial features. He also looks ahead, so you work towards a result that stays beautiful in the long term. He takes plenty of time to get to know you, discuss your wishes and give honest advice about what does and does not contribute to a beautiful, natural result. His goal is not to change your face, but to help you be the freshest and most confident version of yourself.

An eye for detail

Clients describe Koen as calm, approachable and meticulous. Thanks to his refined injection techniques, aesthetic sense and eye for detail, treatments are carried out with great precision and attention to comfort and safety. He works exclusively with high-quality products and always aims for a subtle, harmonious result. That way, you leave the treatment room not with a different face, but with a fresh look in which you still recognise yourself.

"So far, so good Losing weight with medication I had an online consultation; it was clear and I was able to ask anything I’m very satisfied!"

"The support I received throughout my programme was pleasant and professional. Thanks to the excellent support from dietitian and coach Nicole de Haan, I felt well looked after. A really lovely clinic offering dedicated and expert care. I’m very happy with the experience!"

"I’ve been coming here for a few years now. They always listen carefully to what you have to say, give you clear explanations, and the treatment is carried out in a very calm and professional manner. I’d definitely recommend it!"

"A lovely clinic with a neat, professional look: a friendly welcome, complete with a cup of coffee. The first impression is immediately positive. Then there’s the free consultation: it can be a bit nerve-wracking the first time, but they take plenty of time to offer expert advice, so you can make an informed decision. Really nice. During the treatment, I was put completely at ease, and afterwards I was given a goodie bag to take home."
