 Throughout his development, the Carters maintained a mindset of longevity for the clinic, ensuring that it could operate without them in the future. For 18 months, we worked on developing the heart clinic, Sister Carter said. We partnered with a doctor and other staff. It was training, training, and seeing patients with a hope to work towards making it sustainable. In time, the clinic was indeed running without the Carters. First, Sister Carter stepped away four months before the end of their mission. A month later, Elder Carter, too, stopped seeing patients.
