CalenDR was started by David Kim, a 33 year old who lost his mother to breast cancer. His mother fought for 5 years before succumbing to the disease. David has always regretted not being aware of early detection and screening for the disease.

Today, only a small percentage of the population are aware of what immunizations & screenings they should be doing. CalenDR wants to provide this information to the public. Early detection & preventation are still the most optimal methods of disease prevention.
