• David is a hard worker, intent on making sure that the job is done right. His strong work ethic encourages all that are around him to excel and desire excellence with every objective. I know David to be a man of character and integrity, able to identify those same traits in those that he interacts with.
    David is, and will continue to be, a positive force in all of his endeavors

  • I have worked with David on several occasions, both as a sound service provider and a sound system contractor. David always puts the client's needs first and maintains a cool head in the face of unexpected changes. His work is first-rate and he is a pleasure to work with.

  • On August 24, 2012 David Bretzke came to Rock Church in Arlington, TX to look at our sound system. Not only was he extremely knowledgeable about sound equipment, but he was also incredibly easy to work with. His demeanor and kind disposition put everyone at ease. We have served as Pastor and First Lady of Rock Church for five years and our sound has never sounded better! David took what we had and performed a "miracle". 😉 We were absolutely ecstatic and blown away by the results he brought about in just a short period of time. We plan to contact David in the future for our audio needs. We highly recommend his expertise to anyone. We've been in ministry for over 20 years and in our opinion, David is the best in the business, hands down!
