“I get to enjoy spending time learning about my patients through my visits with them,” says Dr. Kowalski. “I want to get to know my patients to be able to tailor their medical care into what they want and what their expectations are. I work for the patients and here to help them achieve their goals and understand their treatment plan.”

In his free time, Dr. Kowalski enjoys spending time with his family, hunting, fishing, wood working, spending time in his yard.
