"Any clinic would be incredibly lucky to have your experience and expertise. You are the consummate professional and definitely provide a 5 star service!!"

S. Houghton, Kent.

"I met Fiona at a networking event about two years ago where she was giving a talk on Colon Hydrotherapy, and was immediately impressed with her knowledge and quiet, calm manner. I have been seeing Fiona for nutritional advice and regular colon hydrotherapy treatments ever since and highly recommend her. (I had been looking for someone to go to for colonics for years, and was very happy to finally find someone I felt comfortable with). Fiona gives regular talks to groups and offers her excellent treatments in Tunbridge Wells, Battle and Hastings.  She works to a very high professional standard and is gentle, caring and sensitive. I recommend her to many of my own clients as I feel that nutrition and colon hydrotherapy is so key to overall health and well being - certainly critical to skin condition!"
