Josh Nitz
Dental Assistant
Josh met Dr. Irelan in early 2016 after being referred by his mother who had seen Dr. Irelan for an emergency. Josh had a traumatic sports injury as a child involving his front teeth and the time was right to proceed with a more permanent solution. The superior care and results provided him were enough to form a friendship with Dr. Irelan that would soon lead to a desire to join him in the dental field to assist in providing the same quality of care he received.
Being a self-taught watchmaker and former aerospace welder, Josh understands the necessity for precision and how the mechanical aspects of previous professions translate well into the dental field. Knowing that root canal therapy can be an unnerving thought for many people, he provides excellent chair-side manner and understanding that will ease the worries a patient may have. Josh is pleased to be assisting not only an endodontist that provides state of the art dental care, but his best friend that can hopefully prove to you that root canal therapy can be a pleasant dental experience. In his free time, Josh enjoys scuba diving, motorcycles, metal detecting, and visiting his family in Wisconsin.
