A total Godsend!

A total Godsend! My son was couch ridden, restricted diet, terrible eczema, couldn't sleep, terrible dog allergy. Now he can eat whatever he wants, travels, and can have a dog again. Dr. Foster has given my son and our family quality of life back!

No more allergy pills.

I suffered with allergy problems most of my life, every spring and fall. 5 years ago, I heard about Dr Foster and decided to try his therapy out. Since then I have been allergy free, no more allergy pills , nose sprays , headaches ,etc . I had 4 or 5. Treatments for different allergies. I went back this year for a check and need 2 follow up treatments. I would recommend anyone with allergies to see Dr Foster for evaluation and treatment. I wish I would have discovered him earlier.

This is Lfe Changing!!!

I treated gluten at advanced allergy, I was terrified to eat gluten for a week so I could do the blood test for celiac. I carried a cookie around with me for 2 hours trying to get up the nerve to eat gluten. Astoundingly 1 week later I have ZERO SYMPTOMS!!!! This truly feels like a miracle! I’m still having a hard time believing I can actually eat gluten! This is LIFE CHANGING!!! Now I want to tell everyone I know about it!!! Thank you, April!!!
