Our digestive team

Highly skilled, ready to help

Dr. Danilewitz

Dr. Danilewitz

Meet our gastroenterologists at Mercy Philadelphia: Mervyn Danilewitz, MD, and Ronald Concha-Parra, MD.

Both are board-certified. Together, they have 40-plus years of experience treating almost any digestive problem, from swallowing disorders to hemorrhoids.

Still, they do specialize in certain areas. A key one: treating hepatitis C with powerful new medicines that can clear the virus that causes it from the body—and help prevent complications like liver cancer. Both doctors also focus on:

  • Treating pancreatitis, which can be life-threatening
  • Managing chronic diseases, such as Crohn’s disease and ulcerative colitis
  • Screening for colon cancer

Dr. Danilewitz also performs specialized endoscopic procedures to treat tumors in the pancreas and bile duct.

You won’t be a number

Should you turn to Dr. Danilewitz or Dr. Concha-Parra, you can count on care that is as compassionate as it is knowledgeable. “We pride ourselves on compassion,” Dr. Danilewitz says.

That care is also timely. No one waits long for a consultation. “So many people come to us in great discomfort,” he says. “And we can make a huge difference in their lives—or even save a life. Knowing that, we make ourselves available.”
