Growing up in a medically-underserved community, Dr. Casey Charlton knows how important it is to bring high-quality healthcare to vulnerable patients.  It’s why he chose MLK Community Healthcare’s Internal Medicine Residency Program. “This is a place where what you do really matters, where the people you help really need and appreciate your help,” he says. It’s also a learning opportunity like few others. “Working with underserved patients, you’ll see advanced presentations that you only read about in books.  You’ll work with patients who truly appreciate your care. As a physician, you will grow both your skills and your heart.”

Dr. Shibata shares that medicine has a place close to his heart, having lost a family member at a young age. He’s volunteered in Mexico, which helped fuel his passion for helping the less fortunate and the medically-underserved. “Aside from working as hard as I can to provide the best medical care possible to the community, I want to be a voice, an advocate, for the underserved who live here,” he says. Dr. Shibata chose the Internal Medicine Residency Program at MLK Community Healthcare to help make real changes in the community.
