Dorothy Amanda Knutsen, MD

Infectious disease specialists play a quiet but essential role in New York’s healthcare landscape. They bridge the gap between primary care and complex medical cases—especially when travel, emerging pathogens, or chronic conditions complicate a diagnosis. Dorothy Amanda Knutsen, MD, operates in this space, offering expertise that often goes unnoticed until it’s urgently needed.

Her office sits on the 20th floor of 222 E 41st St, a stretch of Midtown where glass towers mingle with older brick buildings. The area hums with the kind of energy that comes from being steps away from Grand Central, yet the practice itself remains focused on the kind of precision medicine that infectious disease demands. Patients here might seek guidance on everything from post-travel screenings to long-term management of conditions like HIV or Lyme disease.
