Surely, one can opt for doing MBA after doing MBBS. Depends if they wish to do it for just fulfilling personal wants and dreams or for professional reasons - such as opening a hospital and medical Science chain. The financial part and management part behind establishing and operating a hospital business would better be understood in MBA. Some good MBA colleges are located in India. One about which I have heard good things is LM Thapar School of Management. It is located in Dera Bassi, Mohalli. They have a beautiful campus with all kind of facilities from academic to personality building/extra-curricular ones. Their academic curriculum for MBA is also recommendable with helpful staff and management. Their placements are well managed, organized, helpful and productive.
