Rusty Tweed:

Rusty Tweed is the owner and CEO of Mold Zero Services LLC. Several years ago a member of Rusty’s family came down with a long term respiratory illness that did not properly respond to treatments from various doctors, specialists, and naturopaths. It was finally discovered that the cause was a mold infestation in the person’s home. This was followed up by a considerable amount of research and investigation into an effective, reliable and non-toxic treatment that would remove the mold and not leave any toxic residues behind. After many months, Carol, Rusty’s wife, came across a non-toxic, EPA-registered, technology that was available. Rusty and his spouse were so impressed with the process, they had a team come all the way from Utah to Los Angeles to treat their home. It worked so well that Rusty decided this was a wonderful business opportunity. To be able to inexpensively destroy mold and do it with a methodology that used a non-toxic process and left a person’s home free of mold and fungus for over 90 days had to be a wonderful thing.

This led to the formation of Mold Zero Services LLC and securing the rights for this non-toxic, patented process for all of California and half of Florida.

That was 5 years ago. Today, Mold Zero Services LLC has expanded many times and has several locations in California and Florida. It has successfully treated over 1,500 homes, schools, and businesses, with more treatments being conducted every week.

Raymond Alemania:

Raymond Alemania was looking for a new opportunity and decided to join forces as a partner with Mold Zero Services LLC in California. Immediately, Raymond realized that the revolutionary dual dry fog technology would truly be a game changer in the mold remediation industry. Since that day, his priority has been to spread the word of Mold Zero and bring this life-changing technology to families and businesses to make their living and working spaces safe.
