His practice flourished and soon he was recognized as a proficient and well renowned doctor in the field of ENT. His fame and recognition grew over the years and soon he was considered to be one of the leading ENT specialists and surgeons of the state. The clinic that he set up in Bharalumukh was soon overwhelmed with patients and he was finding it difficult to accommodate the large numbers. He also realized that the city needed a specialist ENT hospital. Hence, he decided to construct his own hospital. He laid the foundation stone of his hospital in the year 1989. NIGHTINGALE HOSPITAL was thus born.
