Caring For All Your Needs

Dr. Von Stieff uses a holistic approach to addiction recovery. Through his research and 25 years of experience, he has identified the need to prioritize your physical and emotional needs. By using a medical model, your caring doctor shows how addiction is a disease and not something you should be blamed for.

As part of his approach, Dr. Von Stieff will ensure you are comfortable and will get to know you as an individual. He loves to show his fun side too and keeps his patients in good spirits.

Over his career, he has become famed for his pioneering treatments, highlighting how addiction can be corrected by “balancing your brain.” This method refers to caring for the mental side of addiction, not just trying to cater for the physical implications.

In fact, he knows so much about this subject he wrote a book about it.
