Drs. Koen van Maren is a cosmetic physician and works in the clinics in Duiven.

Biography

Drs. Koen van Maren studied Medicine at Radboud University in Nijmegen. After graduating, he gained broad clinical experience in general surgery, where accuracy, attention to detail, and safe practices are paramount. He has now been working as a cosmetic physician for over two years and combines his work in aesthetic medicine with his training as a general practitioner. This combination allows him to view each patient with both a medical and aesthetic eye.

Fresh and self-assured

Drs. van Maren believes that a fresh, rested appearance starts with subtle improvements that suit a person's natural facial features. The long-term perspective is also very important, allowing for a sustainable result. Therefore, he takes ample time to get to know his patients, discuss their wishes, and give honest advice on what does and does not contribute to a beautiful and natural result. His goal is not to change faces, but to empower people to be the freshest and most self-assured version of themselves.

Patients describe Koen as calm, approachable, and meticulous. Thanks to his refined injection techniques, sense of aesthetics, and eye for detail, treatments are performed with great precision and attention to comfort and safety. He works exclusively with high-quality products and always strives for a subtle, harmonious result that matches each patient's unique appearance. This way, people leave the treatment room not with a different face, but with a fresh appearance in which they still recognize themselves.

"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."
