About us

Our clinic is a well-established name in Hazerswoude-Rijndijk, where Dr Kroll laid the foundations in 1971, bringing 47 years of passion for the profession to the practice. Since 2018, Dr Oran Marvan has been continuing this tradition of loving care, having worked closely with Dr Kroll since 2007, first as an intern and later as a colleague.
We are an independent practice where personal attention and a permanent, small team are central to the care of you and your pet. By combining our many years of experience with the latest techniques, we offer high-quality care without the need for you to be referred elsewhere.

Who are we?

The foundations for dr.Oran Marvan’s vision were laid early on, after which he opened his first clinics in The Hague in 2009. However, his connection with dr. Kroll remained strong, rooted in the time they worked closely together as colleagues at the practice in Hazerswoude-Rijndijk. This long-standing friendship and shared passion for the profession meant that the takeover in 2018 was a natural progression. It enabled us to continue the life’s project of dr. Kroll whilst modernising it to meet current veterinary standards.

We believe that the best care is provided when we look after your pet as a team and involve you, the owner, closely in the process. Animal welfare is always our top priority, and we work in close consultation with you to reach a joint decision that suits the situation and your expectations. We are an independent clinic, which means we have the freedom to charge fair prices and always choose the treatment method that is best for your pet’s health. Respect for both people and animals is at the heart of everything we do.


Our team

Our close-knit team consists of dedicated professionals who have been working closely together since our days at the clinics in The Hague. Led by dr. Oran Marvan, who has over twenty years’ experience in surgery and orthopaedics, we work alongside dr. Natasja and veterinary assistants Esmee and Danielle to provide personalised care, driven by a shared passion.

We made a conscious decision to move to Hazerswoude-Rijndijk so that we could provide high-quality, dedicated veterinary care in a small-scale setting. Curious about our staff’s backgrounds, specialist knowledge and their own pets?

Our clinic & equipment


Our facilities are equipped for comprehensive blood tests, microscopy and ultrasound, enabling us to reach an accurate diagnosis quickly in our own laboratory. The modern operating theatre is fitted with advanced inhalation anaesthesia and monitoring equipment for heart rate and oxygen saturation, allowing us to perform even complex surgical procedures safely in-house.
