About Us
Our veterinarians collectively possess over a century of experience, providing comprehensive small and large animal veterinary services.
As we are ever growing and expanding it is important to us that we add vets to the GDK family who share the same values and work ethic as we do. Our priority is always the best interest of our patients and we strive to make that abundantly clear to pet owners.
GDK goes the extra mile and we want our patients to feel at home.
For this to be made certain involves good communication between veterinarians and pets owners. This will allow the pet owners to make well-informed decisions about their pets health. We maintain the highest health care standards but also emphasise the importance of prevention and the healing process.
Our technology and equipment are the best and latest on the market as we strive to be as effective and efficient as possible in keeping your pets healthy whilst happy.

Our vets continually undergo SAVA organised educational courses to always be up to date with the latest diseases, treatments and technologies.

Completed my studies in 1987 qualifying as a Veterinary Surgeon. Started my military service 1987 in Askham in the Kalahari as State Veterinarian.
Mainly working with sheep, cattle, camels and game. In July 1989 I joined a mixed practice in Schweizer-Reneke North West. In my 26 years in Schweizer-Reneke I did various dairy farms, stud as well as commercial cattle, sheep, goats, game and of course all small animals. Working in a radius of about 300 kilometres was always a challenge and time-management essential.
On 01 September 2015 it was my privilege to open a brand new practice in Malmesbury Western Cape, Groenkloof Dierekliniek. A member of RUVASA and a founding member of V-Network.
Grew up in the Western Cape and went to school in Bellville.

Qualifying at Onderstepoort in 1993, Corla worked as a Clinical Assistant in the Department of Veterinary Tropical Diseases and obtained an Honours degree in Infectious Diseases in 1995. The next year she decided to broaden her horizons and travelled to the United Kingdom where she lived and worked for the next 8 years, primarily around the greater London area.
In 2004 Corla decided to expand her horizons again and moved to Hong Kong where she initially worked at the Hong Kong SPCA. In 2008 Corla finished a study on the prevalence of hyperthyroidism in cats in Hong Kong and was rewarded with an MSc.
In 2010 Corla attained Membership of the Australian and New Zealand College of Veterinary Scientists in Feline Medicine.
Since then, she had been biased towards cats and worked for 4 years at the first cat-only clinic in Hong Kong. Her clinical interests include internal medicine, ultrasonography, geriatric care and the human-animal bond.
In 2020 Corla returned to South Africa to complete a Post Graduate Certificate in Education (PGCE) at the University of Cape Town. Since then, she had been working in both Hong Kong and South Africa but has now moved back to South Africa on a permanent basis and is very excited about joining the team at Groenkloof Animal Clinic!
Corla is passionate about educating the next generation and is involved with a new education center in Klipheuwel. In her spare time, she enjoys nature’s beauty on a bicycle (or a motorcycle).

I grew up on a farm just outside Bloemfontein in the Free State, where my love for nature and animals began. As a young boy, I spent time with my grandfather in his dairy and helped with sheep handling. This is where my passion for production animals started.
I pursued a BSc degree and was later accepted into veterinary school. I developed a strong interest in surgery and now have the opportunity to practice this passion.
I still enjoy the challenge of working with various species, including horses, wildlife, and more.
I completed my community service year in Malelane and later worked in the Free State.
I am married to Madelein, and we have a young daughter. In October 2024, we decided to semi-migrate to the Cape.
I look forward to helping every patient to the best of my ability.
