"Dear Dr. Orbay,


I would like to take this opportunity to express my gratitude for the effective health care extended to me by yourself.  Whether it's been a relatively minor issue or one of a somewhat more serious nature.  I've always appreciated the calm manner and thorough explanations that have accompanied the varied treatments.  I think that healthcare should always be rendered in such a caring and warm environment as found in your office (but often isn't).  


I would have no hesitation in recommending you to friends or customers and wish you continued success."

Dr. Mark Orbay’s Naturopathic Approach to Patient Treatment


Dr. Orbay has been treating patients of all ages with complex chronic conditions for over 20 years. He serves both individuals and families in a holistic and personalized manner. 


He recognizes that our stress-induced modern lifestyle can be a major factor leading to chronic disease. Add to that, environmental toxicants like pesticides, industrial pollutants, heavy metals, as well as microorganisms and these additional stressors can shift our normal physiological function to pathological changes and disease.


As a natural medical detective of sorts Dr. Orbay’s approach is to:

  1. Understand what are the major stressors impacting each patient.

  2. Reduce or eliminate the major toxicants.

  3. Make appropriate dietary and lifestyle recommendations.

  4. Prescribe the necessary natural medicines to address the condition(s) at hand.


“When health is absent,

wisdom cannot reveal itself,

art cannot manifest,

strength cannot fight,

wealth becomes useless,

and intelligence cannot be applied”
