About Us


A team of audiovisual and event experts devoted to creating memorable experiences for clients at home and abroad for over 30 years.


CSR was established in 1947…

…in White Plains, NY, as Colortone Camera. The company expanded and eventually grew to become one of the largest audiovisual dealers in the Tri-State area with multiple Camera Stores and over 25 in-house hotel contracts to provide on-site AV services. In 1987, Colortone Camera expanded into Cleveland, Ohio at the request of the Stouffer Tower City Plaza Hotel (now the Renaissance Cleveland Hotel) to become their in-house AV vendor.  

Soon after arriving in Cleveland, owner, Bob Leon, began concentrating his energies on building a traveling staging division and in 1993, purchased the Ohio division of Colortone Camera (with his wife, Karen) and began to expand outside of Ohio.  

In 1998, CSR expanded into Salt Lake City to meet the needs of existing clients who were headed west as well as to attract new business. This move proved advantageous when we were awarded the primary contract for the Salt Lake Olympic Committee to provide audio-visual services at the 2002 Winter and Paralympic Games. 

In 2008, CSR decided to close the Salt Lake City office and focus all efforts on expanding into the Cleveland market and continuing to travel the world with our clients. Today, we are a highly experienced team of Designers, Engineers & Technicians that have worked all over the world. We’ve staged events in China, Singapore, Budapest, Vienna, Berlin, Barcelona, London, Amsterdam, Santiago, Montreal, Mexico City, and almost everywhere in the US.

We have produced events in ballrooms, Conference Centers, tents, cruise ships, wineries, beaches, parks, and parking lots. If you can imagine it – we can create it.

Today, CSR is a full-service audio-visual supplier and event production company headquartered in Solon, OH. Our 10,000-square-foot warehouse stores every major brand of audio-visual equipment necessary to produce a successful event locally, nationally, or internationally.

If you can imagine it – we can create it.
