"The owner of the company, Phil Tantella, spent time on the phone with me giving me lots of information beyond what his scope involved. He was so helpful and knowledgeable. Working with his company was a good experience from start to finish. The process takes time, and Phil stayed in touch, keeping me up-to-date so I could move forward with other planning."
