Mark Fisher began down the path towards a life with ozone in the early 1980’s when he moved to the SF Bay area. After installing solar systems for a few years he started a solar service department for Stanford Energy, a solar and cogeneration micro-utility company.

When National Water Management Corporation lost its funding in the early 1990's, Mark started Ozone Water Systems, Inc. - a small regional ozone service company. In 2002, with the addition of John Overby, Ozone Water Systems became systems integrators and began providing "the right system for the right application".

John spent four years in ozone applications by supporting the worldwide sales efforts until Osmonics/GE purchased Lakewood Instruments, a cooling tower control company, and John went to work with this division to help expand ozone into the cooling tower industry. John then went to work for GDT Technologies in 2000 promoting ozone mass transfer equipment; integration of gas into water with the Mazzei injector
