“Since early on, I knew that I wanted to help others.”


Provider Bio down arrow

Dr. Joseph Chojnacki (pronounced cho-NOCK-ee) is a clinical psychologist who focuses on adults with a wide variety of psychological issues.​​​​

“There are all kinds of ways to help people,” he said. “I look at each person’s unique circumstances and work collaboratively with them on a treatment plan.”

Patients can develop psychological distress arising from such varied reasons as coping with chronic illness, difficulty with insomnia and relationship problems.​​​

​​​Dr. Chojnacki coordinates Behavioral Health’s psychological testing program, which includes computerized programs that help provide a profile early, resulting in more efficient and effective care. He also is the department’s liaison with Sleep Medicine. That’s key, because insomnia is often related to psychological problems.

​​​He and his wife, Jodi, came to Marshfield in 1996 when they were newly married and ready to start a family. The small community’s overall quality of life including strong educational systems, exceptional access to quality health care, reasonable cost of living, and a safe community appealed to them and continues to today.

​​​He enjoys family time with their two children, traveling, biking, and enjoying the outdoors.
