Dr HEIDI DUVEL

FAMILY PHYSICIAN MB ChB (Pret.)

I enjoy all aspects of family practice, but being a mom of two, I have a soft spot for the kiddies that I see. I love being part of this community and making my patients healthier and happier.

I obtained my medical degree at the University of Pretoria. After completing my internship and community service at McCord and Hlabisa Hospitals, we moved to Cape Town where I was a medical officer at Red Cross Children’s Hospital and Groote Schuur Neonatal Unit. Once back in KZN, I started working at Linkhills Medical Centre in 2015.

Dr BERNHA VAN DER MERWE

FAMILY PHYSICIAN MB BCh (Stell.)

I'm Dr. van der Merwe, an enthusiastic general practitioner who loves taking care of families.

My interests cover a wide range of medical needs, but I have a special interest in women's health and weight loss. I'm here to provide empathetic support and evidence-based guidance, whether it's routine check-ups or embarking on a healthier lifestyle. Your well-being is my priority, and I'm excited to partner with you on your health journey.

I graduated from Stellenbosch University in 2016, did my internship at King Edward Hospital and finished my journey in the public sector at Inanda C community health centre. The next few years I worked as a general practitioner at Medicross in the Bluff before finding our forever house in Assagay. I’ve been part of the Link Hills family since February 2023 and plan on making this my home.
