Our Dedicated Health and Wellness Experts

CLT, AAP, CCT, Owner
I began a gut-wrenching journey searching for help in 2001 after my son’s digression from a vaccine injury.
At 19 months old, beginning within hours after the MMR vaccine, he tragically lost his ability to talk and became a child I no longer knew or understood.
Over the next two years, 17 doctors informed me that “He’ll need to be on Ritalin” or stated, “Don’t get your hopes up.”
In 2003, an NAET doctor was the first to improve my son’s immune system by eliminating allergies he’d developed as a result of the vaccine injury.

Chiropractor
Dr. Underberg joined Nourish in 2021. He is originally from Eagle Grove, Iowa. Coincidentally, he spent several years of his youth only a block away from where Nourish is today! Coming back to his old "stomping grounds" has been
very well received.
After High School, John attended Iowa Central Community College, where he first found a love for Chiropractic. His desire to help ease people's pain without the use of drugs allowed him to help many who had very few options.
