About Wanjiru Landers, MS, PA-C
From a young age, Wanjiru Landers has been deeply passionate about caring for others. Being a provider and caretaker has always been more than a career goal—it’s been her calling. There are different ways of caring for others, for instance, the food we eat. She has long believed that the food we eat and the way we care for our bodies can profoundly influence not only our physical health but also our mental and emotional well-being.
Before pursuing her path to becoming a Physician Assistant, she worked as a personal trainer. That experience reinforced her belief that true health is holistic—nurturing the body, mind, and spirit together.ā
