I have been to many psychiatrists over the last 17 years in my battle with the effects of being bipolar. Only Dr. Mantz had the right combination of insight, compassion, thoughtfulness, an extremely broad range of in-depth knowledge of nutrition, herbs, vitamins, other supplements, exercise, meditation and an excellent understanding/mastery of western psychiatric medicine. Dr. Mantz invested a lot of his time and his professional expertise in determining the best path for me and was able to successfully lift me out of a 2.5 year-long excruciating and debilitating depression.
