About Gold Coast Power Systems, LLC

Gold Coast Power, Inc. Established in 1982 and incorporated in 1985, is one of the pioneer companies to have its own computer database of diesel engines and diesel related equipment from all over the U.S. John Rubano, president and founder, began working with RPM Diesel in 1968, and worked at the authorized Detroit Diesel facility for 14 years. He accomplished his factory training and certification for 53, 71, and 92 series diesel engines in that period, and ran the service department of fifteen technicians for eight years. In the last thirty years, Mr. Rubano has amassed a network of Detroit Diesel, Caterpillar, and Cummins dealer and distributor contacts, upon which Gold Coast Power can draw to find you, the buyer, the best possible deal.

Stephanie Walker began working with RPM Diesel from 1986 to 1995, and joined Gold Coast Power from 1995 and still going. Stephanie has been John Rubano's right hand woman who handled everything from sales, shop oversight, and customer relations.

In 2017, John Rubano has officially retired and has handed the reins over to Stephanie Walker, his personal assistant since 1995.
