Foundation Leadership

Foxhall Foundation is the visionary brainchild of married, Washington, DC based physicians Kristin E. Thomas (Yamamoto), M.D. and Joshua S. Yamamoto, M.D. Their shared desire to “help everyone age well” by educating the lay community as well as the medical community about the need and ability to prevent stroke and care for the aging heart and vascular system led to the creation of Foxhall Foundation.

Dr. Kristin E. Thomas

Dr. Kristin E. ThomasDr. Kristin E. Thomas is a Michigan native who graduated with a degree in American history from the University of Michigan, and subsequently earned her medical degree there as well. She did her internship and residency on the Osler Medical Service at The Johns Hopkins Hospital. Upon completion of her training, she became the first “hospitalist” physician of Johns Hopkins before accepting the position of Assistant Chief of Service (Chief Resident). She gave up a promising academic career in the department of medicine at Johns Hopkins to marry a naval officer stationed at the National Naval Medical Center in Bethesda, Maryland. She then agreed to work with a prominent private medical practice in Washington, DC. Her husband joined her several years later when the two formed their own practice, Foxhall Medicine, PLLC. She has long been dedicated to the care of her patients and has watched them age, some more gracefully than others. In 2015, she started the Foxhall Foundation, which initially worked to help provide services for patients with dementia.
