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 father managed commercial accounts at that time.
While in high school, Mike gained expertise in backflow prevention and cross-connection.
In 1982, he received his LA County tester certification while handling major corporate accounts.
Following college, he entered the local union's apprenticeship program for plumbers and steamfitters.
After four years of training, education, and testing, he earned dual certification as a plumber and steamfitter.
This accomplishment shows his capability in both trades throughout his apprenticeship.
