    I’ve always had good experience with RTK, and had an especially good experience with Ron, he explained everything, was super knowledgeable, respectful, and kind. It seems like a great company to work for, and it comes out in the folks who works for them.

    I had Lydia come evaluate my apartment and I couldn't have been more pleased! She had been recommended to me specifically, and I now know why. She makes you feel very comfortable with being in your home, explains everything very clearly, presents cost-effective options, and is very knowledgable about her work and the process. I haven't gotten results back yet but regardless, I greatly appreciate her kindness and professionalism during the testing!

    Our inspector was timely (actually early) was very polite and answered all of my questions. He explained the whole process thoroughly and educated us about how mold grows and the different types of mold. He told us what to expect with the mold remediation and if we wanted, they could give us names of companies that they have vetted. I would highly recommend our inspector Mr. Anderson.
