About Us

Our Loveland chiropractors and Nutrition Response Testing practitioners at Inside Health promote whole-body health for the whole family.


Inside Health is the top Nutrition Response Testing™ and Chiropractic clinic in the Loveland and Fort Collins area.

Our Story:

Since 2010, Drs. David & Lauren Kolowski have been promoting natural healing through Chiropractic and Nutrition Response Testing.

They are “fortunate” to have had several significant health challenges in their lives.

It was through these experiences that they learned what truly works to regain and maintain good health.

The practitioners at Inside Health are continually refining their approach to help you be healthy and live simply.

We have the experience and the training to help save you the time, effort, and money while you reach your health goals.

Our Philosophy:

We believe that everyone deserves to enjoy optimal health.

We believe that health is the natural expression of a life well lived.

We believe that your body is smart. We must respect this intelligence and use it instead of trying to outsmart it.

We believe that it is more important to express life than to suppress illness.

We believe you deserve the opportunity to be your best.

Katie Ward, loveland nutrition response testing practitionerKatie Ward, Nutrition Response Testing Practitioner

When Katie became a yoga instructor, she began listening to her body and seeking ways to remedy the chronic neck and head pain she had after a car accident. During that journey, life continued to offer her lessons through digestive issues, kidney infections, gallbladder attacks, imbalances, and inflammation. She learned the impact stress had on her body. Finally, when she became a Nutrition Response Testing patient, she began to truly heal.
Nutrition Response Testing and whole food supplements have changed Katie’s life. There is a lot of confusion out there when it comes to our health care, especially with nutrition. Katie truly believes that the answer to feeling our best begins with what we feed our bodies.
In 2019, Katie began learning about Nutrition Response Testing and nutritional coaching and is so grateful that path led her to become a practitioner. She is passionate about helping others achieve their health goals while sharing her understanding of our body’s amazing wisdom and ability to heal. Great health is possible when we support the body as nature intended!

We promote whole-body health for the whole family through Chiropractic Care and Nutrition Response Testing™.
