Hiebert Center Favicon


The Hiebert Center for Healthy Aging offers innovative, integrated, individualized wellness programs designed to turn back the biological clock of life and help you look, feel and age your very best.


Aging, and the diseases it can bring, begins at the cellular level. At the Hiebert Center, we measure three essential age-related factors in order to neutralize the issues and preserve healthy DNA to effectively reduce age-related disease. Our methods can help you live longer … and better.


We will tailor a comprehensive, health-promoting treatment plan just for you, which may combine aspects from both traditional and functional medicine, including holistic, alternative practices where and when appropriate. It all begins with a complimentary consultation during which we’ll discuss your personal goals and concerns. Your unique plan may include cell-defending techniques, nutrition, fitness, natural hormone replacement, methods to reduce chronic inflammation, supplement replacement and aesthetic skin care. We will also consult with your other physicians and healthcare practitioners to ensure every aspect of your care works in perfect harmony.


Our practice is fairly unique to the greater Kansas City area. We embrace this model because it gives us the freedom to spend as much time with our patients as we (not an insurance company) deem necessary. This allows us the freedom to prescribe and deliver a higher level of personalized care spanning traditional and restorative medicine. For a flat yearly fee, you’ll have access to our physicians and practice, as often as you need.
