Meet Our Team of Transplant Professionals
Early intervention and education are critical to slowing the progress of kidney disease. That's why we've worked hard to develop an environment of both excellence and compassion, where organ recipients as well as donors are completely informed of the disease process and taught about the available options.
Complete management of the disease involves regular monitoring not only of kidney function but also of blood pressure and blood glucose levels, cardiovascular risk factors, anemia and bone and mineral metabolism. At ECMC, we have a multidisciplinary team of experts who are specially trained to provide a comprehensive range of services and are known throughout the region for their skills.
