At Sheehan Natural Health Improvement Center, we believe that our bodies were designed to heal. Many symptoms and diseases can be traced back to where either the healing process got stuck or something important was overlooked. When you find that important link and do what’s necessary to help nature along, you can restore your health.


We offer natural and holistic solutions for healing. We are drug-free and non-invasive. We are dedicated to our practice of Nutrition Response Testing, Functional Medicine, Chiropractic, and Craniosacral Therapy.


We have helped our patients for over 23 years with conditions such as: irritable bowel syndrome, digestive issues, fatigue, fibromyalgia, chronic pain, neruopathy, diabetes and blood sugar issues, immune system issues, depression, allergies, asthma, eczema and other skin problems, just to name a few.

Nutrition Response TestingSM

Nutrition Response Testingsm and Designed Clinical Nutrition provide safe, effective relief for many health problems. They comprise part of a complete health and wellness program using non-invasive assessment techniques, individualized nutritional recommendations, whole food supplements, and herbs, to get you well and  keep you well for a lifetime.


Chiropractic adjustments provide excellent relief for back pain, neck pain, joint pain, and many other issues. Chiropractic adjustments realign the spinal joints and put them back into their correct position, removing pressure from delicate spinal nerves. Healthy backs are one of the foundations of wellness.


Functional Medicine

90% of disease is based on diet and lifestyle factors, not genetics. The conventional medical system has not been able to address the growing flood of chronic disease solely with pharmaceuticals. In order to make a difference, we need a new paradigm of health care. Functional Medicine offers hope for the future.
