Karen Leon

Owner/Vice President

BIO: Karen Leon grew up in a military family. Frequently stationed in Europe though moving between France, Germany and Spain, Karen became fluent in German and French at an early age. Later, she settled in Boulder, Colorado where she attended college, graduating with a degree in Communications.

While living in Manhattan, Karen worked for Colortone Camera as the Operations Manager. This is where she met Bob, ultimately relocating to Cleveland and founding CSR.

Karen is responsible for the financial side of CSR. She takes great pride in her passion for the A/V industry. She believes CSR has attracted an excellent staff, which is able to provide the best customer service and experience for its clients, regardless of venue or location.

When not at work, Karen enjoys traveling. She moves easily between skiing in the Alps and lounging on the beach. With a son in Boulder (the leaf didn't fall far from the tree), and a daughter in Oregon, Karen spends a lot of time out west.

One of Karen’s annual traditions is her birthday celebration at the Telluride Blues and Brews Festival. She also enjoys exploring new places and cultures, especially when doing so involves listening to good music and tasting great foods!

Rob Mier

Director of Sales
Rob is CSR’s director of sales and a member of the Executive Committee. He has been with CSR for 12 years and was a client for five years before that. He believes his greatest contribution to the company is his ability to create and maintain long lasting customer relationships, and turning clients into friends.

In his spare time, Rob enjoys cooking Italian food, playing a good round of golf, and reading good books. A devoted Tribe fan, an unabashed follower of Notre Dame football, and a perpetual volunteer for worthy causes, he is looking forward to his next vacation cruise.

When asked what his favorite ballroom to stage an event is and why, he said, “The next one because you always have to look ahead." He enjoys working hand-in-hand with my clients to develop their knowledge.

He would like it noted that he has impeccable fashion sense, and that his nickname is “Dr. Evil.”
