Mr. Abdus Samad Shaikh, the founding Treasurer, took charge as General Secretary during the most turbulent period, in 2004, when conditions had gone against OSA. OSA was facing onslaught from within as well as without and its existance was under serious attack. One of our own members turned our foe and started a dirty tirade against us, complaining to Anjuman, Charity Commissioner, Police, Incone Tax and Mumbai Municipal authorities. Anjuman threw us out unceremoniously, abrogating all its rights and neglecting all its good deeds. He, with support from Mr. Haroon, turned the tide and we could sail out of rough weather. He was instrumental in legal fight with Anjuman, Charity Commissioner, Income Tax and Municipal Corporation. But OSA lost its adopted Municipal schools where we used to conduct our famous OSA Guidance Classes, which were the financial backbone of OSA. After taking over as President in 2015, he streamlined the organisation which was in a disarray after the long fight and regained lost ground. Today, OSA is comfortably moving ahead in most of its objectives.
