Leaders in DIY Phone Repair

We started out and continue to operate within a family owned business, which specializes in the repair of cellular phones. Not only have we repaired cell phones since 1997, being certified through Nokia and Motorola, but actually started out repairing pagers. Recrystalling, re-tuning and refurbishing them for customers and retailers in our town as well as surrounding cities. We repaired both pagers and cell phones before they were widespread and affordable. We started repairing cell phones when they were simply cellular telephones.

Today we continue to serve as a leading repair facility. The cell phones today have evolved to unimaginable heights and continue to evolve every month. We strive to keep up on the latest technology and to maintain a leading edge in the industry. We do this to know the latest in the market but mainly to provide an environment where people know the knowledge we give is sound and true. We saw a need to bring our extensive knowledge, and repair insight from our shop to a larger and grander scale. We also noticed how the cost of repairs and phones has skyrocketed and continue to increase, and how people are looking to save wherever they can. We want to give quality trainings at affordable prices for every person who has a desire to learn phone repairs.
