YS Chowdary was the youngest of the four children. He spent most of his early life in Vijayawada, Miryalaguda, and Hyderabad. He was named after his grandfather Satyanarayana.

Mr. YS Chowdary has strong family ties. His company “Sujana” is a combination of the first two letters of his mother’s name (Smt Susheela Kumari) and the first four letters of his father’s name (Shri Y Janardhana Rao). The Yalamanchili family originally hails from the twin villages of Ponnavaram and Peddamaradali.

His father, Y Janardhana Rao, worked for the government of Andhra Pradesh where he held the position of Superintendent Engineer in the AP Irrigation and Power Department. His mother, Susheela Kumari, is a homemaker.


Engineering and love for technology were ingrained in Mr. YS Chowdary right from his childhood. Hailing from an educated family, he holds a bachelor’s degree in Engineering from the Chaitanya Bharati Institute of Technology (CBIT), Hyderabad, and a Master’s Degree in Engineering from the PSG College, Coimbatore.

His love for engineering and his insatiable curiosity about the ‘mechanism of how things work’ led him to create a series of engineering and manufacturing companies that went on to become the dynamic business conglomerate, Sujana. His entrepreneurial brilliance is the foundation on which the Sujana Group was built.


The Yalamanchili family originally hails from the twin villages of Ponnavaram and Peddamaradali. His paternal grandparents, Shri Yalamanchili Satyanarayana Chowdary and Smt Yalamanchili Dhanalakshmi, migrated to Hyderabad.


Y Janardhana Rao, father of Y S Chowdary, is an engineer, who worked for the Government of Andhra Pradesh. He retired as a superintendent engineer in the AP Irrigation and Power Department (formerly known as the Public Works Dept). His wife, Y Susheela Kumari took great care in bringing up the family. They have four sons and a daughter.


Y.S. Chowdary is married to Smt. Padmaja. They have a son Karthik and a daughter Naga Chandini. A natural leader and a sensitive man, YS Chowdary has struck an enviable balance between being a successful entrepreneur and a caring family man. Both his children are married.



A personality like Y. S. Chowdary always has the big picture in mind. Beyond profits and balance sheets, the humanitarian in him has enabled several initiatives to improve the quality of life in our society.

His family background helped him to naturally engage with the socially and economically underprivileged. He imparted a deep-rooted sense of giving back to the society among the employees of his company.

The Sujana Foundation is a fitting example of the ‘humane’ side of Y. S. Chowdary. A joint initiative with the NTR Foundation, the Sujana Foundation has made a massive difference in rural and semi-urban areas in Andhra Pradesh through social initiatives that have touched lives and made a significant difference.

The Foundation supports and runs several programmes of education, for the children of its employees, for physically and mentally challenged children across south India, besides general support for several schools and colleges.

Sujana Foundation supported several sports initiatives at various levels, from supporting sports in schools and colleges, to sponsoring and training sportspersons in various sports.

The Foundation also conducts regular free health camps and has established a College of Medicine, which includes post-graduate and nursing courses.


YS Chowdary became a member of the NTR Trust and took interest in its activities, streamlining the trust’s operations and ensuring that its actions were aligned with the noble vision of the founders.
Besides his role as Chairman of Sujana Group, he finds time and energy to join the leadership of the NTR Trust and take up several initiatives.
