About
Dr. Yolandie McCoskey is a board-certified family physician and the founder of Harmony Health LLC in Myrtle Beach, South Carolina. She earned her undergraduate degree at the University of Redlands in Southern California. She then received her medical degree from Loma Linda School of Medicine in 2011. She completed her residency training with the Kaiser Permanente Family Medicine Program in Fontana, California, from 2011 to 2014. The American Board of Family Medicine granted her board certification that same year. After residency, she practiced as a primary care physician with Southern California Permanente Medical Group before relocating to Myrtle Beach.

Dr. McCoskey grew up in Virginia Beach, Virginia, after being born in Johannesburg, South Africa. She traces her calling to medicine back to age two, when she visited her father recovering from severe burns covering 80 percent of his body. Watching him survive that experience shaped her conviction that navigating illness requires care, support, and hope. She brings that conviction to every patient relationship, treating conditions from diabetes, hypertension, and thyroid imbalance to acute infections, mental health concerns, and weight management.
