Advanced Surgical Care

As a general surgeon in Muscle Shoals, Dr. David Cozart, MD performs surgical procedures to treat conditions affecting the abdomen and related structures, like hernias or tumors.

Known for his compassionate and caring approach with patients, board certified general surgeon, Dr. Cozart, is among Muscle Shoals’s most skilled minimally invasive surgeons.

What this means to patients is less pain, less risk, and quicker recovery times than those generally experienced by patients who undergo open abdominal procedures, or surgery performed the 'old way'.
