Our Specialty, Focus & Research

Conditions We Work With

Digestive Health

Digestive health is truly at the ‘core’ of our specialty and born out of Dr. Ruscio’s personal health journey. The health of your gut has a far reaching impact. 


The impact of the gut on the thyroid is underappreciated which is why we are passionate about assisting people in better addressing this important connection.  

Immune Health & Chronic Infections:

Histamine levels and mast cell activity are also strongly impacted by the gut. In some cases another layer exists that triggers these issues, often including an infection or environmental exposure to mold. 

  • Histamine intolerance
  • Mast cell  
  • Lyme & Chronic infections
  • Mold 

Brain Health 

The brain-gut connection is profound, and accounts for why many of us notice an increase in feelings of depression, brain fog, insomnia, or anxiety, as it correlates with a flare in digestive symptoms.

  • Brain fog
  • Insomnia
  • Depression, anxiety
