Mike, a master plumber and plumbing contractor from a family of plumbers, has deep industry knowledge.
As a child, he learned the trade by helping his father and joining him on service calls in the summer.
His dad was responsible for commercial accounts back then.
Mike became knowledgeable in backflow prevention and cross-connection while in high school.
He earned his LA County tester certification in 1982 while managing large corporate accounts.
Following college, he entered the local union's apprenticeship program for plumbers and steamfitters.
He completed four years of schooling, training, and testing to become a dual-carded plumber and steamfitter.
This achievement demonstrates his ability to handle all aspects of both trades during his apprenticeship.
This experience gives Mike an advantage in today’s market, as he has been a skilled journeyman for over 20 years.
Mike promptly identifies problems and acts accordingly every single time.
