My 12-year-old son has been doing keeper training with Cesar for about 8 months. He has made great strides during that time. Cesar does a great job with him working on the basics and fundamentals. Cesar pushes him during training (in a positive manner) and also works with him on the off-field stuff. I highly recommend Cesar for keeper training and also for field training players. We look forward to more training and also watching Cesar in his Dallas Sidekick career.
