Doug’s integrity is outstanding! By giving me specific instruction and careful review of my figures, he was able to accurately reduce my Federal tax burden to just $845.This is a net savings of $3,977! I gladly signed the check for his fee, which was less than half of what I had paid to file the same schedules in previous years. Thank you Doug and your Book of Numbers!
