Dr. Kramer uses a unique process, NRT, Nutrition Response Testing to find underlying causes of health conditions and remedy them; I had amazing success with this process and rely on it for repair and maintenance. Nice to know I can stay healthy by correcting problems and rebuilding instead of using medications to mask symptoms! He corrected some very serious issues I had from multiple surgeries over the years; things that would have lead me to kidney failure or other problems had they not been handled by treating their cause (in my case, injections of toxins to destroy a growth). I highly recommend seeking out this treatment for minor and major health issues! Victoria D. Warwick NY
