David, and his crews are first rate in our book. They approached our project in 2 phases, allowing for settlement of phase 1, before moving on to phase 2 and finalizing our project. The project was an exterior drainage system, with stone work, fine grading, finish grading, plantings and finish/clean up. It was done on budget and within our timeline to finish. The crews were efficient, careful with our existing plantings, and friendly and respectful to us. We couldn't have asked for more.
