My name is Dr Casper Joubert and I am currently a first year registrar in Occupational Medicine at the University of Stellenbosch. I am happy to be back at my Alma mater after completing my MBChB degree in 2008. With the completion of my internship and community service I embarked on a journey that would ultimately end up being more than 10 years in duration and take me to more than 35 countries.

I was in the very fortunate position to practice medicine in the UAE and in Mauritius. Through this journey I practiced medicine in many different disciplines as well as at multiple different levels. I was exposed to a wide range of pathologies and grew and appreciation to the practice of Evidence Based Medicine.

I am currently happily married and have two beautiful boys. In my spare time I enjoy reading and I am a passionate golf enthusiast. I also currently hold a R&A Level 2 Golf Rules Officiating certification. I am always looking for opportunities to get out onto the course so don’t hesitate to contact me.
