I didn’t know which engineer to choose from. Upon searching, Larry was the only one to point out issues in my mix. It was clear that Larry cared and wanted to achieve the best possible outcome for my project. Clear and extremely informative. The outcome was beyond what I expected. Hire someone who cares– Larry is that guy!
