We have known and been treated by Darrell since his early days in practice. He has been gifted with the ideal combination of wisdom/insight and a genuine interest in the health of his patients and is faithful to use the gifts he has been given. In addition to the regular visits that help us be able to exercise and enjoy life in our 50’s, his work on our behalf includes successful nutritional therapy to treat my wife’s hyperactive thyroid. The mainstream medical community recommended radiation, which would have led to lifetime drug dependence. As a result of the program Dr. Kilcup recommended her thyroid returned to normal function and has remained normal for the past 6 years. He is the trustworthy real deal. The five star rating is appropriate – not because Darrell is perfect, but because he has earned the highest rating among medical professionals we have ever seen.
