From an early age, Zdenko decided to learn all he could about the human body and mind. He became a medical doctor, earning his degree in 1986 from the Medical University of Belgrade. In 1993 he also received a diploma in Alternative Medicine from the European Center for Peace and Development, University for Peace, established by the United Nations, in Belgrade.
In 1990, Zdenko established his Center ALTER in Belgrade; a medical practice integrating Alternative Medicine, science, art and consciousness development fields. The Center ALTER was a great success and he opened his first school in 1993, sharing his knowledge and teaching his system for self-healing and self-restoration, while also hosting popular TV and radio programs. From 1990-1997 Zdenko documented more than 10,000 healings using his Arsenijevic System and unique abilities. In 1994 he participated in a special study on consciousness and the human body energy fields. The results were presented in several international conferences, including one at Columbia University, New York, entitled Acupuncture Points and the Human Energy Field in 1998.
Emigrating to the United States in 1997, he began practicing his spiritual energy healing method and teaching this system, along with other techniques and practices for personal self-development around the world from his offices in New Jersey and Pennsylvania. He now offers an undergraduate and post-graduate program. Zdenko travels frequently throughout the United States meeting people and conducting the transformative Liberty Series and workshops on meditation, energy healing and related topics.
