I had the opportunity to work and give the original training to Rolando and I can say that all the years we worked together he has been a good coworker and a good friend. Rolando is a quick learner and he always gave the best of him at any moment and allways delivered a final product with the finest qualities. Rolando os a good adition to any organization and I'm looking forward to work with him in the future.
