About Schweiger Dermatology Group

Schweiger Dermatology Group was founded to help make excellent dermatology care accessible throughout the Northeast. In 2010, Dr. Eric Schweiger started the practice with a single location in Midtown Manhattan. When he saw the need for high-quality dermatology care that did not require weeks or months of waiting to see a qualified provider, his vision of a multi-location practice was born.
