Dr. Ebert Steyn

After growing up in Port-Elizabeth, I obtained my B.Ch.D degree from the University of Pretoria. I completed my community service in Cradock in the Eastern Cape and then moved to Cape Town. This was where I met my partner and we, along with our cocker spaniel, Pablo, decided to finally settle in and call the beautiful Knysna, home. Iím excited and thrilled to be part of Dr Zonnesteinís team.

I find the entire scope of dentistry fascinating, from pain management to full scale oral
rehabilitations and Cosmetic Dentistry with special interest Orthodontics and Advanced Restorative Dentistry.

In my spare time I enjoy music and being an animal and nature lover, try to take advantage of all the outdoor activities the Garden Route has to offer.
