Carol Zanmiller CEO, Cosmic AES

This was my second deal with Capstone. Noting that they were chosen a second time, after thoroughly interviewing the competition, says it all. The professionalism and knowledge of the process detail were impressive. I felt comfortable and had complete trust in them. They found opportunities for a better outcome of which I was unaware. They certainly have my highest recommendation.
