I've tried almost every colonic clinic in So Cal and this one wins hands down in best service. They spent a lot of time helping me with what foods I should be eating and what foods I'm allergic or "sensitive" to. They made me feel comfortable and they really cared and really wanted to help me. The other places I went to made me feel like they were just in it for the money even though they were a little cheaper than Zen Cleanse. I referred my husband to them because he wanted to lose weight and after going a few times he lost almost 20 pounds. I feel like I got a better value at Zen Cleanse and now I won't go anywhere else.
