i have been going to dr. clark weekly since aug. 8th for allergy problems. in the beginning it didn't seem to be making any difference but now after going 6 sessions in over a month i have made a lot of progress. tomorrow i will be having an exam with him and i am excited to see how much improvement i have had. i know i can feel a lot improvement in my body. i would definately reccommend him to anyone who has allergy problems.
