Marc John D. Barredo, MHA

Program Manager, GME Residency

Marc John Barredo is the program manager for the Kaiser Permanente Mid-Atlantic States Internal Medicine Residency Program. He has been an integral part of the accreditation process and manages the multiple priorities to ensure the program’s success. After achieving accreditation and recruitment of the inaugural class in 2020, he pursued operational and consulting roles within Kaiser Permanente.

Before coming to Kaiser Permanente of the Mid-Atlantic States, Barredo worked at Walter Reed National Military Medical Center and the George Washington University Medical Faculty Associates in a similar role. Barredo is married to a graphic designer who makes his pictures look stunning all the time, and he likes to spend time with his family outside of work.

HOW I THRIVE

I completed the Rock-and-Roll Half Marathon in 2024, so I think I like running. I love volleyball more though, so I play 3-4 times a week in recreation centers and leagues. I also like U.S. National Parks, and I dream to visit all 63 of them some day.

HOW I THRIVE

By spending time with my family. Together we enjoy skiing, kayaking, biking, and occasionally a competitive bowling game. We enjoy spending quiet vacations at the beach and at our home away from home in Florida. We also live within walking distance of my husband’s family farm, so there is never a shortage of fresh fruits and vegetables.

What our residents have to say

After 3 years of being a resident at the KPMAS IM Residency Program, I can confidently say my clinical and professional experiences have been monumental in making me the physician I am today. These experiences were built by the constant learning environment and amazing resources provided by KPMAS, including my daily interactions with patients, staff, and faculty members. 

Hamdi Abdeen, MD, Chief Resident 2025-2026

I was drawn to Kaiser Permanente because it feels like the kind of place where the way care is delivered matches what I believe good medicine should look like. I’ve always been impressed by how innovative, forward thinking, and inclusive the organization is, but what stands out most to me is its commitment to caring for the whole person, not just treating disease, but understanding the medical and socioeconomic factors that shape someone’s overall wellbeing.

On a personal level, I’ve spent the last decade in the DMV, and it’s become home for me. That connection makes it especially meaningful to train in a system that delivers care to the local community.
