Board-Certified Dermatologist
Fellow of the American Academy of Dermatology

Dr. Dunnigan opened his Greenville office in 1995. He has practiced dermatology since 1991. He earned his undergraduate degree at State University of New York at Buffalo. He received his medical degree from Midwestern University.

Dr. Dunnigan is board certified in family practice and dermatology. He has a fellowship in dermatopathology from UT Southwestern Medical Center in Dallas.

When not caring for his patients, Dr. Dunnigan enjoys skiing, scuba diving, hiking, and spending time with his three children. He went into medicine because he found it mentally challenging. “It’s also a way to help people change their lives for the better,” says Dr. Dunnigan.
