Meet the Business Owner

Vitaliy T.

Business Owner

Although the Tsertseil family has been servicing the glass industry for over a decade as freelancers, Knock On Glass did not become official until September of 2012. It was founded by the eldest son Vitaliy who grew up fascinated with the limitless possibilities of glass and mirror applications. The Tsertseil’s immigrated to United States in 1995 from Moldova, a small country in Eastern Europe. Moving to a new country was a tough decision which took its toll on Vitaliy’s family as they faced new challenges and language barriers. Nevertheless, all hardships paid off as the family made a name for themselves in the glass industry. Vitaliy and his close family installed shower doors and storefronts during the day, while at night he studied business management at Baruch College in Manhattan. Vitaliy’s extensive knowledge of the glass industry and his managerial education finally pushed him to legalize their business entity. His superior quality and dedication quickly gained utmost respect.
