Dr. Derek is an excellent chiropractor! I suffered from severe migraines and thought I would give chiropractic a try on the recommendation from a friend who saw Dr. Derek and had seen great results from their low back pain. After 2 weeks of care I haven't had a single migraine in 3 months! Not only did my migraines stop, so did my allergies! I haven't felt this good since my teens . . . maybe even better than then! I've sent two other friends to Dr. Derek for other problems and they have also seen great improvements! I can't say enough about Dr. Derek at Purple Mountain Chiropractic. Whatever you have going on, even if you don't think a chiropractor can help, give him a try and see what happens before you dismiss it. You might be surprised. :D I'd give 10 stars if I could!!
