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.

Erich Berger

Beginning his career in Ohio on the higher education side of the AV industry, Erich Berger began working for his alma mater in 2016 and spent the next 5 years developing his passion for both AV systems and programming, using Extron to create control systems for classrooms and event spaces and configuring audio DSPs. He received multiple Extron certifications and achieved status as an Extron Authorized Programmer.

During his time both working and studying at Ashland University, Erich was involved in the development of an educational tool, Sim-U-Sell, one of the leading sales-management simulation tools currently used in higher education, as a back-end programmer. Having enjoyed creating this software, and expanding his understanding of development, he went on to spend much of his free time experimenting with multiple programming languages, including Python, PHP, C#, Java, Javascript, MySQL, HTML, and Lua, creating programs such as a solar panel control system, games, and a basic ticketing system.

In 2022, Erich moved from higher education to a commercial integration company where he continued building upon his experience programming Extron systems and began training with other notable platforms, including Q-Sis, Crestron, AMX, and Biamp. Now, as he begins his work with Control Concepts, he looks forward to using the skills he has cultivated thus far in his career while also developing new skills and bringing a fresh perspective to the team.

When he’s not working, Erich enjoys throwing frisbees with his two dogs, playing board games with his wife, and spending time outdoors. He notably has hiked over 600 miles of the Appalachian Trail in a single leg and hopes to hike the rest of the trail some day. He is a graduate of Ashland University with a Bachelor of Science in Computer Science.
