Donna Knezevic holds a Bachelor’s Degree in Social Science and brings over 12 years of hands-on business experience from the electrical and retail sectors. As the founder of a successful electrical supply business, Donna built her reputation by delivering practical solutions, expert planning, and trusted advice to electricians and project managers across a range of complex builds.

Through years of industry exposure, she became acutely aware of a silent but growing health concern—chronic exposure to electromagnetic radiation (EMF) from smart meters, high-voltage towers, and mobile networks. Driven by her commitment to health and safety, Donna began researching real-world solutions that could neutralize these invisible stressors.

Her search led her to co-found Biohealthhealing Products, bringing to market the internationally recognized Pozitron Plus range—an advanced line of wellness technologies designed to combat EMF radiation and geopathic stress in homes, workplaces, and biological systems.

Donna now focuses her energy on educating and empowering individuals to take control of their environment and their well-being. With a rare combination of commercial experience and deep personal conviction, she continues to be a driving force in the movement for cleaner, safer, and more energetically balanced living spaces.

Prof. Aleksandar “Saša” Zalepugin was a pioneering mind in the field of radiesthesia, best known for blending traditional energetic sensitivity with modern innovation. In 1995, faced with personal health challenges, he developed the first prototype designed to protect sleeping areas from harmful effects of underground water flows and natural radiation.

His work caught our attention in 2009, when he humbly presented his invention. After formal testing revealed impressive results, he became an integral part of our development team. With tireless commitment, deep knowledge, and countless tests, Prof. Zalepugin helped shape the foundation for what would become POZITRON PLUS.

Thanks to his expertise, and years of collaborative innovation, we expanded the original concept to include protection from modern technical radiation—while also enhancing energy flow in the human body and stabilizing energy in living spaces. His contribution was instrumental in creating a globally recognized, multi-functional product now backed by scientific testing, certifications, and multiple international awards.

Prof. Zalepugin passed away in 2022 at the age of 92, but his legacy lives on through every product we create and every life we protect.
