Dr Tinus (MJB) van Zijl

Position: MBChB 2003 University of Stellenbosch. Licensed member of the Medical Council of Canada.
Make an Appointment: BOOK NOW

Special interests: Orthopaedics and sport medicine, paediatrics, student health, men’s health, small surgical procedures.

In private practice in Stellenbosch since 2009.I started my journey in a small Highveld town in Mpumalanga called Evander, where I also matriculated in 1998. I completed my medical degree at Stellenbosch in 2003, after which I did my internship and community service in Kallie de Haas Hospital in Potchefstroom. I was fortunate enough to join my father (also a GP) in private practice in Secunda in 2006. After obtaining my Medical Council of Canada licentiate, I joined Stelkor Doctors in 2009. Being part of a family of doctors made me appreciate what a privilege it is to work with people. I feel humbled to be allowed to share in their illness, joy, sadness, struggles, pain and all the other emotions and complexities of their lives. I can say with honesty that I truly love my job.

Raising two beautiful daughters gave me insight into the challenges that parents face, and that is why I particularly enjoy paediatric medicine in a GP practice setting. Sports medicine and orthopaedics is also one of my interests, as sport has always been a part of my life.

Living in Stellies, and being a Matie myself, student health lies close to my heart as students bring a vibrant energy to our town and adds to its character.
When I am not caring for my patients, you can find me spending time with my awesome family, exploring the great outdoors or enjoying the beauty of nature, either trail running, mountain biking or hiking. I believe that a healthy work-life balance is essential and I strive to inspire my patients to prioritise their own health and mental wellbeing.

Philosophy: “The only person you are destined to become is the person you decide to be”

Dr Renscha van den Berg

Position: MBChB 2005 University of Stellenbosch, Diploma in Sedation (UWC).
Make an Appointment: BOOK NOW

In private practice since 2008 in Stellenbosch.
Special interests:  Women’s Health, Psychiatry, ADHD, Menopause, and all aspects of general medical practice.
“Ek het grootgeword in Evander, Mpumalanga, waar my pa ‘n GP was vir 35 jaar. Ek en my twee broers het almal dokters geword en om die kuns van medisyne te beoefen en te bemeester sal altyd vir my ‘n voorreg en ‘n strewe bly.  (Dr Tinus van Zijl is my broer)”.

Although I like the variety that general practice brings (variety is the spice of life!) I am married to a psychiatrist and my interest in this field naturally developed around morning coffee and holiday camp fires! ADHD is a field within psychiatry that I have a keen interest in.  In recent years the space where women’s health and psychiatry converge has also fascinated me.  The effect of the menopause and other hormonal changes like premenstrual disorders and the post-partum period on both the physical and psychological wellbeing of women has fueled my passion to further my knowledge and contribution in this field.

Hobbies:  Parenting (I am a mother of three), Gardening, Travelling, Reading.

Philosophy: “It’s far more important to know what person the disease has than what disease the person has.” – Hippocrates –

Dr Frieda Esterhuyse

Position: MBChB 1986 University of Stellenbosch. MFamMed (Family Medicine) University of Stellenbosch 1992.
Make an Appointment: BOOK NOW

I graduated with a MBChB from Stellenbosch University in 1986, whereafter I specialised in and pursued my passion of family medicine to complete my MFam Med in 1992. I have been in private practice since then: firstly in Stellenbosch, with a short break to Kraaifontein. I have been back full time in Stellenbosch since 2000.

My ma, Annemarie, was ’n wiskunde-dosent by die universiteit – in een van haar lesings het sy my uit die klas uit gejaag omdat ek te veel gepraat het! Wel, dit het nie veel verander nie. Ek hou daarvan om met my pasiënte te gesels en om hulle regtig te leer ken. My pa, Willie, is ’n filosoof en hy het my geleer hoe belangrik gelykheid, geregtigheid en meegevoel is. Daarom het ek ’n dokter geword – omdat ek mense wil help.

My medical interests encompass all aspects of Family Medicine, with a special focus on women’s wellness, rheumatology, and autoimmune disorders. In my free time, I love spending time outdoors in fresh air and nature. My hobbies include hiking, travelling, and gardening.

Filosofie: “Die lewe is mooi – nie omdat dit perfek is nie, maar omdat daar altyd iets is om voor dankbaar te wees.”
