Colleen Van Egeren is thrilled to be joining the Wisconsin Institute of Plastic Surgery Dermatology Division. She is a Green Bay native and has been practicing Dermatology in the Green Bay area since 2007. She has trained under some of the most accomplished dermatologists including Dr. Ashish Bhatia at The Dermatology Institute of DuPage Medical Group in Naperville, IL.
She received her undergraduate degree in biology and psychology at Marquette University and went on to receive her Masters degree in Physician Assistant studies at Rosalind Franklin University of Medicine and Science.


Colleen’s philosophy has always been to provide patients with an environment where they feel important and heard and that their needs as a patient are met with the utmost compassion.
Colleen loves dermatology because it offers a unique opportunity to really get to know your patients. “I love seeing patients as teenagers for acne and then getting to see them as adults for skin exams. It has been truly a blessing to watch many of my patients grow up over the years and still be able to treat them”. Colleen enjoys spending time with her husband and three children, boating, traveling, and anything outdoors!
