Ruben Acosta, MD, FACP, FACG


Dr. Ruben Acosta has always had a strong desire to care for others in their time of need. Dealing with a new medical diagnosis can be scary, and he is driven to help patients navigate that difficult journey.

Today, Dr. Acosta is dedicated to making interactions between providers and patients more effective. His view is that patients will only share critical information with their providers if they trust them. His goal is to earn that trust and ensure their priorities are met.

Board certified in internal medicine and gastroenterology, Dr. Acosta is a fellowship-trained gastroenterologist with advanced training in endoscopy and particular interest in the following conditions:

  • – Pancreatic disorders
  • – Pancreatic cysts

Dr. Acosta earned his undergraduate degree from the United States Naval Academy before completing postbaccalaureate studies and his medical degree at the University of Connecticut in Mansfield, CT. He underwent internship and residency training at the National Naval Medical Center in Bethesda, MD, before pursuing a fellowship in gastroenterology at the National Capital Consortium. As part of his fellowship training, he engaged in nine months of advanced endoscopy training at the University of Maryland in College Park, MD.

“I focus on the patient-centered model of healthcare. I consider myself the expert on the medical knowledge side, and the patient is the expert on themselves. By creating a safe space for patients to share information regarding themselves, I can provide more effective and accurate care,” Dr. Acosta said.

Before joining Capital Digestive Care, Dr. Acosta served as a captain in the Medical Corps of the United States Navy, most recently serving as a staff gastroenterologist and director of endoscopy at Walter Reed National Military Medical Center. He was also an Associate Professor of Medicine at the Uniformed Services University of the Health Sciences in Bethesda, MD. He served on the ASGE Standards of Practice Committee for three years, authoring many papers on the safe, quality focused performance of all endoscopic procedures. Outside the office, Dr. Acosta spends his free time with his wife, their three children, and their dog. He likes to travel and enjoys many outdoor activities including bicycling, hiking, and swimming.
