I have owned a computer store for over 25 yrs. but knew little about repairing cell phones – I cannot believe how much we learned this past week. Rene is wealth of knowledge and a great teacher. It’s like going from being a 1st responder at the start of the week and a Doctor at the end of the week. Also I cannot say enough about Frank (the mad Scientist) who assisted Rene with the class – This Man is the real deal – one of the smartest and kindness man all in one package. If you are in the Las Vegas area and Get Frank as your teacher you will be in for a treat. I am 64 years and a little slower then the rest of the class but Frank took me under his wings and kindly helped me keep up with the class. THANKS TO BOTH RENE AND FRANK = AMAZING CLASS
