About Renew Health Co.
Founded by Diane Hackner (formerly Diane Shalevski) in 2016, Renew Health Co. is a holistic wellness practice based in Preston, Victoria and is dedicated to empowering individuals on their journey to optimal health.
At Renew Health Co., our philosophy is rooted in uncovering and addressing the true cause of your health concerns, rather than simply treating symptoms. Our approach focuses on restoring and nurturing the body's internal terrain, creating an environment where healing can naturally unfold. Guided by the principles of terrain theory, we support the body’s innate ability to return to balance, vitality, and long-term wellness.
We take a thorough and holistic approach to understanding your health. Using in-house modalities such as live blood analysis and iridology, along with trusted external testing services when needed, we gain a detailed insight into your internal health picture. With this information, we create a personalised protocol designed to safely and effectively support your body's unique healing journey.
Our philosophy centres on the understanding that true healing is multifactorial, embracing not just physical health but also the emotional, mental, and environmental factors that influence wellbeing. We place a strong emphasis on education and self-empowerment, supporting our clients with the tools, knowledge, and confidence needed to make informed decisions about their health.
We believe that vibrant health is your birthright. A life reliant on medication and overshadowed by pain is not the life you were meant to live. If you are committed to reclaiming your health, we are here to guide and support you in creating lasting, transformative change.
