Since selling their pharma interests 7 years ago, siblings Malvinder and Shivinder Singh, have focused on building a health care and financial services empire. Their listed Fortis Healthcare, overseen by older sibling Malvinder, is a nationwide chain of 55 hospitals. Scaling back from an ambitious regional expansion, it is now targeting the domestic market. Younger sibling Shivinder, recently gave up his business responsibilities to devote himself to Radha Soami Satsang Beas, a spiritual group to which the family is linked.
