Tom Vaughan, MD, president of Kent Diagnostic Radiology Associates (Dover, Delaware), points out that the emphasis on growth raises some challenging questions, from a practice-management perspective. He says, “As you grow from being a small practice to being a large one, management becomes much more challenging. In some ways, it can be a luxury to be small.”
