Our Services

Herbal Medicine

Herbs were commonly used before western pharmaceuticals were introduced. Treating and preventing medical conditions with herbs is naturally safe, as an overdose would cause irritation or nausea instead of landing in the emergency room. 


Natural Pain Relief

We specialize in non-narcotic practices in healing pain such as headaches, chronic pain, joint pain, and back pain. We use an array of proven methods such as trigger point injections, chiropractic care, and rehabilitation. Our goal is to treat and relieve your pain permanently instead of using pharmaceuticals for temporary relief. 



Homeopathy treatments is to locate the root of your health issues and reverse them naturally. Homeopathy can treat many chronic and acute diseases, rather than managing or suppressing them. Our doctors are able to provide a deeper healing of mental, emotional, and physical complaints.
