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.
