Drew feels so blessed having the opportunity to lead one of the most capable acoustical consulting and audio-visual design teams in the country. He sincerely enjoys working with the other consultants at AVANT ACOUSTICS and strategizing on how to bring our “more complete” services to more owners, architects, and venues across the globe.
While the project at hand is of utmost importance, Drew is also focused on the long-term client relationship. He is excited to be leading AVANT into our next half-century.
A Professional Engineer licensed in the State of Kansas, Drew received his Electrical Engineering degree from Kansas State University. Several years later, he followed that up with a Masters of Business Administration focusing on business strategy and finance.
When not working, Drew prefers to spend time with his family. He and his wife, Amy, have two children who keep them extremely busy. Camryn is seven and Cecil is five. You might find the Siebert family at a local park or pool enjoying the outdoors during the summer or perhaps doing science and engineering educational experiments at their Overland Park, Kansas home when the weather outside isn’t so friendly.
For 28 years, Bob’s creative audio-visual design and enthusiastic leadership have maintained AVANT ACOUSTICS’ leadership position in the market.
As Senior Vice President of AVANT ACOUSTICS, Bob is actively involved in the design, testing, and commissioning of audio-visual and sound reinforcement systems for all types of facilities throughout the United States and in Germany, Japan, and Korea.
When not designing, testing and commissioning systems – or at KU games – Bob might be off sailing, flying, or running a marathon (yes, he is fast!).
Bob attended Oral Roberts University in Tulsa, where he earned a double major in Telecommunications and Business. He also serves as a guest lecturer for university classes in digital audio.
Bob and his wife (the best cupcake baker ever) live in Olathe, Kansas, with their dog Piper, where they host our wildly successful (or maybe just wild) AVANT pool party in the hottest days of the summer.

Focus
We are a small firm located in the heart of America, just outside of Kansas City. Unlike some other firms that offer a huge array of services, we focus on acoustics and audio-visual systems design because we love this work, and we do it really, really well. There aren't many experts out there with the depth of knowledge and breadth of experience of our consultants.
Longevity
Since 1964, AVANT ACOUSTICS has been delivering easy-to-use systems that sound and look outstanding. Many of our clients come back project after project, including our first ever client - Washington Dulles International Airport, who is a client to this day. We keep clients happy by only designing with the latest proven technology and consistently meeting deadlines and budgets.
Relationships
On most of our engagements, there are two key relationships. One is with the owner...looking out for their best interests and ensuring decisions are made for their benefit. The second is to the architect... helping to deliver their vision for the space, and ensuring the acoustical treatments or audio-visual system supports that vision.
