Dr. Bieley is a wonderful, compassionate physician who has greatly improved the quality of our son, Mark’s life. Mark suffers from depression and anxiety and for years was given one medication after another by physicians who didn’t take the time to investigate if there could be a biological reason for his depressed state. It got to the point where Mark was on such a high dosage of anti-depressants (that weren’t working) that he was constantly sad and in a fog. Dr. Bieley’s extensive information gathering and lab testing revealed several things that very well could be major factors in his depression. He gathered all of the test results and prescribed a custom supplement that contains exactly what Mark’s system needed. We have already seen a major improvement in Mark’s mental and physical state and want to extend our gratitude to Dr. Bieley.
