About Us

Zelner Health Institute’s holistic approach to patients grows out of the understanding that one’s state of just “feeling under par” to seriously suffering from a chronic disease is a continuum caused not from drug deficiencies but from multiple stresses both from within and without. These are most frequently found to be in the area of nutritional imbalances, toxin exposure, and hormone imbalances. Your genetic heredity predisposes you to certain health problems, but does not predetermine your total health. It is proven that lifestyle can positively modify genetic expression.

Humans suffering from unwise choices and ignorance of good health habits as well as from the enormous stresses imposed on us from the toxic environment in which we live. Our staff empowers patients in uncovering the causes of disease and discovering how to reach their health goals through participating in the lifestyle choices that create the healing milieu necessary for the body to heal itself.

Zelner Health Institute offers holistic programs, alternative medicine and homeopathic remedies to patients that address the foundations of health including optimal nutrition, toxin identification and detoxification programs, hormone replacement and balancing, vitamin/mineral replacement as well as recommending exercise and stress reduction on an individualized basis.

We believe that when combining a natural health and a natural medicine approach a person can achieve optimum wellness. Traditional medicine offers a grossly different approach to healing and maintaining a healthy balance.

Our team of holistic health practitioners in Orlando, Florida are committed to helping patients find natural remedies for a complete wellness program. Zelner Health Institute serves patients throughout Orlando, Winter Park, Maitland, Oviedo, Dr. Phillips, Windermere and the Central Florida area.
