About this leak

Sanderling Healthcare Sanderling Healthcare was founded in 2009 by Dr. Jerome S. Tannenbaum to further one of his personal missions for healthcare – to lower the cost, and speed the construction, of healthcare facilities. As a nephrologist and successful entrepreneur, Dr. Tannenbaum had spent years perfecting his dialysis clinic designs. Known for counting every step made by his nurses and patient care technicians, and having developed roughly 100 dialysis clinics across the country, Dr. Tannenbaum perfected the design of the modern day dialysis clinic. Among the many benefits of working with Sanderling, is the peace of mind to know exactly what a new or expanded hospital facility will cost, and when it will be ready for occupancy.Geo: USA - Leak size: 587 GB Archive - Contains: Files,Excahnge,Bases
