It was in 1983, that Sudarshan Chatterjee came into the United States. To become a doctor was the fulfillment of his mother's dream. Born in Calcutta, he moved to Kanpur and later to Agra from where he graduated in medicine. He trained further at Rutgers University in New Jersey, finally settling down in North Andover in 1990. He built a thriving medical practice called North Andover Medical Associates, a large multi-doctor group which he later sold to Caritas Medical Group. He moved on to open another practice, New England Medical Specialists with Dr. Anita Kumar on Andover Street in North Andover. He is also an Assistant Professor at Tufts University School of Medicine.
