I recently attended classes instructed by Mr. Jack Manilla in order to acquire a CPO license. Because of what you will... see as an immediate apparent wisdom from many years of experience, I was able to get exactly what I was looking for: not only a knowledgeable course in the commercial pool industry, but confidence in my own ability to pass the given test.I highly recommend Portofino University for anyone searching for success in the operation of a commercial pool service or even if you just want a leg up over the competition in the residential sector.read more
