DIEGO/MARIA/THE Miami Doors & Locks Security Solutions TEAM

4The husband and wife, Diego Castro and Maria Guadamuz leads our team of customer service representatives and technicians.

Diego Castro had a vision more than a decade ago to operate a locksmith business that was a standout in the community. He’s done just that by taking Miami Doors & Locks Security Solutions from operations out of a single truck to a gorgeous, new showroom. His days of having to do everything from answering calls, to servicing customers and billing clients while out on the road are over. Through hard work, honesty and prompt service, Diego has not only created lasting relationships with his clients, but has earned the reputation for being one of South Florida’s most trusted professionals for all locksmith and security needs. He has been an experienced master locksmith for nearly two decades.

Diego could not have done all of this without his trusted partner and wife, Maria Guadamuz, by his side and leading the way. While Diego operates the service side of the business and is in charge of Miami Doors & Locks Security Solutions’s team of licensed and experienced technicians, Maria is the shining light of Miami Doors & Locks Security Solutions, a liaison to customers and in charge of the company’s customer service representatives. With her unique ability to engage people and network among professionals, Maria has helped grow Miami Doors & Locks Security Solutions from a mobile operation to a storefront. The company also has a fleet of 10 vehicles and more than 350 accounts. As the mother of two beautiful and loving children, Maria helps with the day-to-day operations, which include account acquisitions, business management, client retention and networking.

Maria and Diego proudly tell anyone who asks that most of their clients have been with them from the start and they hope to continue being a resource in the community for many more years to come!

Norberto is the technician who is known for going the extra mile and taking on a custom or complicated job. Norberto is not afraid of a project. Whenever a client needs something, he has the answer.
