The thoughts of reaching the needy people to provide proper medical aid and be a medium to contribute the facilities of medical science to those who are sick, injured, needs to be diagnosed with care, and also the urge to work on the betterment of the society's, moreover the nation's healthcare service, led us to the establishment of "Rainbow Diagnostic Centre" on 15th August 2012 at Kalyani, Nadia which provides all facilities of the pathology and radiology services under one roof. It is said that excellence, hard work takes just a few times to get acknowledged and so what happened to us. It is the excellent pioneership of Rainbow's founder Dr. K.P. Haldar and hard work of the whole management team of Rainbow Clinic & Diagnostic and also the trust of our patients in us and our relation with them which paid off so soon to make us able to establish another branch of the diagnostic center in just 2 years, at Madanpur, Nadia.

Throughout the journey, the landscape of our health care services became only stronger and better. With simultaneous support of our team and trust of the patients along with our urge to adopt the global standards of diagnostic and healthcare practices and providing it at an affordable price took us to achieve another milestone of opening "Rainbow Specialty Hospital" in the next 3 years. The construction of Rainbow Specialty Hospital started in 2017 and in 2021 it is all set up with extremely developed healthcare and diagnostic services.
