My name is Alfonso Castellanos, and together with my wife Jennifer Quintana, we founded Underground Machine Detailing, a family dream created to meet the needs of clients who, like us, want to care for and protect their vehicles at the highest level.

Everyone wants their car to look spotless, radiant, and like new every day. That’s exactly where our V.I.P. professional mobile detailing solution makes the difference — at your home, at your office. We know time is limited, so we provide a wide range of services designed to keep your vehicle in perfect condition.

With over 16 years of experience in the automotive field, certified by five global brands — Chevrolet, Ford, Nissan, Volkswagen, and Kia — and after helping more than 6,000 families achieve the dream of owning their first car, we decided to take the next step.

That’s how Underground Machine Detailing was born: a company certified in paint correction and ceramic coating, built on the conviction that vehicles must always be detailed with quality, responsibility, and true value.
