Dr. Bisching believes that your health is by far your most valuable entity. Rather than treating symptoms and managing conditions, he strives to find the root cause of an issue and meet it head-on with Chiropractic, nutrition, and exercise and treat patients with a truly “Integrated” approach.

Shannon Chittenden, Nurse Practitioner

Shannon was born and raised in Iowa where she grew up on a large farm and learned from an early age what hard work was. She graduated from Grand Canyon University in 2018 with her Master’s in Nursing and became a Board-Certified Adult Nurse Practitioner. She has a great appreciation of “conventional medicine” and “modern science” and very much thinks it has its place in guiding patient care in many cases. However, she also believes firmly in providing the kind of healthcare that targets the “whole person” and root causes of illness. She believes in applying more natural therapies and utilizing the body’s own healing and regenerative properties to treat the root causes of health problems, including pain syndromes, versus just treating symptoms of disease processes. Shannon uses treatments to help engage the body’s amazing ability to heal, regenerate, and anti-age itself.  These include regenerative therapies such as Prolotherapy, Platelet Rich Plasma (PRP), and Human Umbilical Cord “stem cell” products. Shannon is also very experienced and proficient in Medical Aesthetics, and therefore, can help you feel amazing on the inside and help you be the most beautiful youthful you on the outside.

Outside of work Shannon enjoys the outdoors as often as she can. She enjoys hiking, camping, riding horses, riding ATVs, Jeeping, running, riding her Mountain bike, and any other adrenaline-inducing activities. She especially enjoys any activity in which she can include her pack of dogs!
