President & Founder

Steve Greenblatt

As one of the pioneers in the independent programming industry, President and Founder Steve Greenblatt has built his career and the company with hard work, dedication, and a commitment to quality service. His focus on these values has contributed to his professional development and is the foundation of Control Concepts.

Steve started his career in 1993 at Crestron Electronics as a Systems Engineer where he spent three years. While at Crestron, he worked on two of the largest projects at the time, gaining extensive technical and professional skills. During this time, Steve built key relationships and gained critical knowledge, while learning the value of organization, time management, communication, and professionalism – all components that have proven to be essential building blocks of his business.

In 1997, Steve’s entrepreneurial spirit led him to start an independent programming company, an offering that was not yet mainstream. While there were initial challenges, it was Steve’s detailed, attentive, and reliable approach that helped propel Control Concepts to steady growth and a loyal following.

Over the years, Control Concepts has formed many long-term client relationships through the company’s development and implementation of AV control programming and software solutions for systems in boardrooms, conference rooms, and classrooms. These partnerships are the essence of why Control Concepts was established and remains committed to helping organizations maximize effectiveness, productivity, and seamless AV communication.

Steve is a graduate of Lehigh University with a Bachelor of Science in Electrical Engineering.
