Dear Larry, Thank you for taking the time to help us with this matter. I hope I can call you with a few questions this time. I never had any questions with the previous two reports, but I do have some questions this time. Again, thank you for coming when I so needed your help. Warmest regards

Hi Larry, thanks again for tooling out to Glamour East Hollywood to tour my rambling, trendy, upscale Silver Lake lodgings. I find that since your visit I need much lower amounts of the supplements I am taking. I am also appreciating the Myss lecture that you so kindly gave me, which I continue to hear, rehear and contemplate. It is very helpfully reinforcing my long-held belief/theory that the fundamental cause of hard to heal illnesses is past emotional overwhelm that has been inadequate processed/released. Yours appreciatively,
Jeff Mayers

Dear Larry, Thank you again for working on instructions for the test procedure. You are right, we won't need it for a while. Thank you for helping us with this project and all the rest. It means so much to be able to get your assistance! Sincerely

Larry, I worked at the Parfitt residence yesterday. With the information from your investigation, John's working knowledge of the house and my efforts, I was able to completely eradicate the EMF issues. I found the neutrals for the circuit went into the sprout room and the circuit for Garret's room and the whole end of the house connected in a junction box in the attic. John knew the box was up there. The circuits went from 9.1, 5.6 and 3.3 A of imbalance to 0.0!!!. I talked to Cindy today and she said it was like a new house, no more clinched jaws and tension. She said they all slept and felt better for the first time since they moved in. It's so satisfying to be able to help people out in this way. Thanks for your help and getting me into the loop.

I finally got the opportunity to look over your entire report in detail. You are to be commended for the important and high professional service that you provide. "I slept and dreamt that life was joy, I awoke and saw that life was service, I acted and behold service was joy." R Tagore I just love this quote! (used in your emails) A testament to the fine work you do. And the joy (and peace of mind) you bring to those who need to make critical life/health decisions based on fact not hype… Truth not myth. Please know how very much I genuinely appreciate your proven expertise.
