Although I initially sought out Dr. Zac for hip and low back pain, his approach to my care revealed massive amounts of underlying stress that was taking a toll on my health in many other ways. My sleep, mood and energy levels were all suffering. When he explained the Zone Technique it all made sense, my glandular system was out of balance! I’ve been under care a few short weeks, but feel major improvements in all areas mentioned, as well as the pain I originally came in for. Highly recommend.
