Associate Director of Medical Education
Kelliann Dell is the Associate Director of Medical Education KPMAS Residency Programs. Dell earned her Bachelor of Science degree in Business Administration from the University of Maryland University College. She worked for the Johns Hopkins University Internal Medicine Residency program for nine years — first as a program administrator and later as a program manager — before joining the Kaiser Permanente Mid-Atlantic States Internal Medicine Residency Program.
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.
