About Me

Look to Dr. William Rossing, a board-certified neurologist at Avera Medical Group Neurology in Sioux Falls, SD, for expert care if you or a loved one has a condition related to the brain, spine or nervous system.

Brain, Spine & Nervous System Expertise

Although Dr. Rossing diagnoses and treats a variety of neurological conditions, he specializes in stroke and movement disorders such as Parkinson’s disease.

He has also been involved in the development of the Stroke Center at Avera McKennan Hospital & University Center and a surgical program known as deep brain stimulation for Parkinson’s disease.

Personalized Neurological Care

Dr. Rossing believes that getting to know each patient personally is an important part of the care he provides. “I like to try and get a sense of who they are as a person and make sure they feel comfortable with me,” he says. “The best part of my job is when I’m able to sit with a patient and explain what’s happening, find a diagnosis and offer a solution.”

He also encourages patients to do everything that they can to be in control of their condition. “When you’re in the driver’s seat and in control of your condition, that’s a much better way to go through life.”

Active Lifestyle

In his free time, Dr. Rossing and his wife enjoy exercising together whether it’s running, kickboxing, weightlifting, swimming or yoga. He also likes to go fishing, hunting and hiking.
