Dr. Bier cares enough to insist on what he knows is right. He really wants to help. 11 years ago I was told that I had metastatic cancer. Dr. Bier asked if I had ever actually been tested. I had not. I got the simple CTC blood test, the results were zero. Now, because I did not have metastatic cancer, I could get a surgery to remove two cancerous lymph nodes that had forced me to take radiation treatment,, and anti-androgen meds for 10 years. I got the miracle I'd been praying for for 10 years.

I can not say enough about our experience! We were looking for an alternative to conventional treatment and we have found so much more. Dr. Bier takes time to understand my condition and truly cares about his patients. I feel much more confident moving forward on my path to healing because of him and the incredible staff.
