Dermatology physician assistants are trained to help you maintain clear and radiant-looking skin, and help diagnose and treat underlying conditions ranging from eczema to skin cancer. It is important to note just how complex the skin is. This organ is your body’s first and best defense against disease. It safeguards your internal organs, helps regulate your temperature, and supplies external signals about your overall health and wellness. Our dermatology physician assistants are trained to understand this important organ and provide treatment for thousands of conditions that can affect your health and appearance.
To gain considerable experience in how the skin functions, dermatology physician assistants seek advanced medical training. At the Wisconsin Institute of Plastic Surgery, Colleen Van Egeren, PA-C, and Megan MacCarthy, PA-C, have 34 years of combined experience treating various skin conditions. They both hold a master’s degree in physician assistant studies and are board-certified by the NCCPA. As dermatology specialists, they would love to talk with you about your needs and recommend a skincare treatment program just for you.

Our dermatology physician assistants can diagnose and treat a wide range of conditions affecting the skin, nails, and hair. A few examples include:
Dermatology physician assistants can identify outward signs of skin cancer, recommending further assessment or treatment as needed.
While most moles are harmless, some can become cancerous. Dermatology physician assistants are trained in identifying moles that appear to be risky or malignant.
Several factors can contribute to hair loss, ranging from unhealthy scalp conditions to autoimmune disorders to simple genetics.
Acute acne breakouts can compromise your skin and impair your self-confidence. Dermatology physician assistants can develop comprehensive plans to get breakouts under control.
Most warts are harmless, but you may wish to get rid of them to improve your appearance. Dermatology physician assistants can quickly and safely remove warts as necessary.
Eczema is an itchy irritation of the skin, usually resulting in a rash. The right dermatological care can help minimize these outbreaks and restore the skin to clarity.
Rosacea is a skin condition that can lead to a red appearance, potentially leading to self-consciousness. Dermatology physician assistants can prescribe the most effective treatments.
This skin condition is characterized by brown or gray spots, often resembling freckles. There are various treatments to restore a clearer countenance.
While there is no cure for this chronic skin condition, dermatology physician assistants can recommend treatments to alleviate the symptoms and make them very manageable.
With time, the skin loses its natural elasticity, resulting in wrinkles, sagging, and hollowness. The right skincare routine can minimize these unwanted effects.
Nails may become compromised in appearance or even functionality. Dermatology physician assistants are trained to treat conditions affecting the nails.
Skin tags are harmless but can become irritated or painful when they rub against clothing. A dermatology physician assistant can safely remove any unwanted skin tags for you.
Often, skin conditions can be most easily dealt with through early intervention. For this reason, we recommend that patients seek care from a dermatology provider any time they notice anything unusual with their skin, whether that is a rash, a sudden outbreak of acne, or a mole or skin tag that appears irritated.
We all have hopes of maintaining healthy, youthful-looking skin for as long as possible. Sooner or later, this will likely require the experience of a skin specialist, such as a dermatology physician assistant, whose role is to help you address any problems or concerns related to your skin, nails, and hair. Megan MacCarthy, PA-C, and Colleen Van Egeren, PA-C, of the Wisconsin Institute of Plastic Surgery offer dermatology services to patients in Appleton and Green Bay.


Patients in Appleton and Green Bay choose Wisconsin Institute of Plastic Surgery because of the skill, experience, and personal attention that our team provides. Learn what other people in our community have to say about our doctors and their treatment.
The American Academy of Dermatology recommends that all adults perform monthly self-exams and schedule an annual, full-body Skin Cancer Screening with a qualified Provider. If you have a personal or family medical history of skin cancer or if you have a large number of moles, our Providers may recommend more frequent check-ups to ensure early detection and peace of mind.
Our dedicated Dermatology team, which includes highly skilled Physician Assistants (Providers), specializes in diagnosing and treating all medical skin conditions, from Acne Treatment to Psoriasis Treatment. Our PAs work directly under the supervision of a licensed physician. They are expertly trained to deliver the same high standard of care, ensuring you receive timely, comprehensive treatment for your skin health needs.
We offer a range of sophisticated options for Acne Scar Treatment, tailored to the type of scarring you have. Our most effective methods often include advanced microneedling, sometimes combined with radiofrequency (RF), and laser skin resurfacing. These techniques stimulate collagen production and improve skin texture, leading to a noticeable reduction in scar appearance.
While there is currently no permanent cure for Rosacea Treatment, the condition is highly manageable with a customized treatment plan. We combine medical-grade topical and oral prescriptions with advanced light and laser therapies, such as VBeam, to significantly reduce facial redness, flushing, and visible blood vessels. Consistent care can keep symptoms under control and provide long-term clarity.
Mole Removal is performed comfortably in our office using a local anesthetic to completely numb the area. Our Providers prioritize minimal scarring and use precise techniques such as shave removal or meticulous excision. The resulting incision site is typically small and fades significantly over time, aligning with our commitment to both surgical and aesthetic excellence.
Blu-U Blue Light Therapy is a non-invasive, gentle Acne Treatment that uses a specific wavelength of light to kill P. acnes bacteria in the skin. This bacterium is a key contributor to inflammatory acne. The treatment is safe, requires no downtime, and is often used in combination with other medical therapies to effectively manage stubborn or cyclical breakouts.
