"Overall, the 11-week program was excellent. Jeff, Katie and Robert should be proud of their work; they took 11 individuals with little or no programming skills and made them productive. I feel as comfortable as I think I could going into my new career with all the knowledge I've gained from this program. Thank you for your sincere dedication to give us your all!"
