Shri. Sanjay Nirupam was born in the village of Rohtas in Bihar. 
 
After completing his schooling in Rohtas, he moved to Patna in 1980 for higher Studies. During this time he took keen interest in active politics & extra circular activities along with completing his graduation (1984) with Honors in Arts, Political Science. 
 
With a burning desire to work for the interest of common man, he moved to New Delhi in 1986 and started his career as a journalist. 
 
In 1988, he accepted an offer from “JAN SATTA” a sister publication of Indian Express which made him move to Mumbai. 
 
In 1993 He joined“DOPHAR KA SAMANA” as an executive editor. God bestowed his blessings upon him in September 1996, as he was chosen to represent the party in the Rajya Sabha. Thus, he started his career as a Parliamentarian. 
 
He emerged as a politician with perfect combination of humanity, sincerity & commitment. 
  
Parliament history shows that he always stood for masses selflessly & fought for the Public issues on the floor of the parliament. Such as the UTI Scam in which the then Prime Minister Shri Atal Bihari Vajpayee offered his Resignation to scuttle the whole controversy, Stock Market Scam in which Crores of small investors lost their money. He was against the irrational and blatant disinvestment & privatization policy which was heavily pushed by the then NDA Govt. At that point of time his view was that it would lead to the further pauperization of the Indian labor forces, repercussions of which are seen now.  He was also vocal against the Naxalite violence gripping the country in most states. He also showed his concerns on the effect of globalization and liberalization on the farmers and the Indian domestic industry. 
 
He was the first person to highlight the irregularity of the sale of Centaur hotel & fought for the rights of the employees. He also vociferously exposed the deal in Parliament & asked for the clarification from Mr.Arun Shourie (the then Disinvestment Minister) who was caught on the back foot. Eventually he demanded for CBI Probe for the transparency on the whole deal which was accepted by the UPA govt. after 2 years. 
 
In March 2005 he resigned from Shiv Sena due to some irreconcilable differences. 
 
In April 2005, he joined Congress to work for righteous ideology as a Spokesperson. In a very short span of time Congress President Smt. Sonia Gandhi appointed him as the General Secretary of Maharashtra Pradesh Congress Committee [MPCC] the State Unit of the Congress party. He effectively worked as an election observer on behalf of All India Congress Committee [AICC] in three states Goa, Gujarat & Nagaland. As a party election observer he was assigned to organize a party rally and a road show of Shri. Rahul Gandhi. 
 
He has been and is working on various social issues (education, poverty, employment generation, development etc.) in his constituency for the down trodden. Free eye camps, youth development programs, tree-plantation, Durga pooja, Dahi Handi, Maharashtra Day etc. are the various events he organizes to bring together different communities & culture. 
 
Since last 10 years he has been organizing Wrestling Tournament with top ranked wrestlers at international level. 
 
As Indian Express once wrote- “He is the one who introduced Chhath Puja to the city of Mumbai which became a part of the festival calendar of Mumbai over a period of time.” 
  
He is also the first politician who accepted the challenge to take part in the reality TV show Bigg Boss. The general thought among the populace is that there is lack of transparency in the political class, where as in Bigg Boss he was under the scanner 24x7 with more than 30 cameras watching.  Viewers loved him for his simplicity and genuineness. 
 
To say the least he is always and easily accessible to common man through various social networking sites, meetings and his “Jan-Sampark” office at Borivili
