Dr. Denise Abernethy

I have been a licensed physician in Wisconsin for over 10 years and am American Board-Certified in Emergency Medicine, caring for emergency conditions and critically ill patients. I gained a particular interest in the specialty of venous medicine after seeing many patients suffer from advanced varicose vein disease and its complications including life-threatening blood clots, non healing ulcers or wounds, bleeding varicose veins, inflammation and swelling to the legs, and skin infections. Using ultrasound guided techniques I have long used in the critical care setting, I am trained to perform these procedures that are safe, well-studied, and minimally invasive. Over the past two years I have worked with the most well-known vein disease experts across the country, obtained the required certification and experience to treat both the medical and cosmetic aspects of varicose vein disease in my own practice. I am a member of the American Vein and Lymphatic Society, an organization geared towards the training and certification of physicians dedicated to the diagnosis and treatment of vein disease. I take pride in making sure my patients are satisfied with the improvement of their symptoms and aesthetic improvement of their spider and varicose veins.

About Venous Medicine

Venous medicine is a specialty that deals with vein diseases and disorders. Although an established field in Europe for more than 50 years, serious interest in varicose vein disease has only developed over the past two decades. In 2005, phlebology (or venous medicine) was recognized by the American Medical Association as a medical practice specialty. The American Venous and Lymphatic Society (AVLS) was founded in 1985 (formerly known as the American College of Phlebology) and was established to improve the standard of patient care related to the treatment of vein disorders. AVLS members, such as Dr. Abernethy, are physicians and allied healthcare professionals with backgrounds in various specialties, who share a common interest and expertise in the diagnosis and treatment of vein disease.

I’ve been going here for treatment, the entire staff is very professional. My insurance covers some of the cost and they allow me to make monthly payments. So happy I took the journey to fix my legs, I would highly recommend giving it a try.


This place has the greatest staff ever!! I’m disappointed that my treatments are coming to an end soon!! 100% attention to your comfort and confidence. They explained everything they were doing after a thorough exam, in a way that I could understand. They mapped out a plan and stuck to it, solving issues I have had for years. My legs haven’t looked or felt this great in years!!! Highly recommend!!
