Oceana Gastroenterology Associates

At Oceana Gastroenterology Associates, we are devoted to the diagnosis and treatment of gastrointestinal diseases.

If you’re like the millions of Americans suffering from GI conditions such as gastroesophageal reflux disease (GERD), gastric cancers, inflammatory bowel disease (IBD), hemorrhoids, or many other serious conditions, we can help.

Gastroenterologist Dr. M. Mazen Jamal founded Oceana Gastroenterology Associates in 2014 to focus on what he does best: caring for patients with issues affecting the digestive tract. Dr. Jamal has been caring for patients in the area of Corona, California, for decades.

Because we specialize in interventional gastroenterology, we’re not just looking to diagnose the problem – we want to treat or resolve the issue for the best possible result.

GI symptoms are serious business: the pain can disrupt your life and may indicate a serious disease that needs to be addressed. Make plans to visit Oceana Gastroenterology Associates to find out exactly what the problem is and what your treatment options are.
