After searching through many different calendar solutions, I settled on TeamUp. I work at the Beckman Research Institute of City of Hope in Duarte, CA. We are a cancer treatment hospital, medical center, basic science and clinical research facility for type 1 diabetes, and have a graduate school for training scientists of the future. We just started using Teamup in our Diabetes and Metabolism Research Institute because we can no longer freely use all of the equipment, instruments, and services available in our building without first controlling traffic in our labs and specialty rooms. It is a terrific solution.
