Dr. Seth Arnall

Dr. Arnall was raised in the mountains of Northern Arizona which is a large part of who he is, it’s there that he gained a love for the outdoors and working with his hands. This love of nature inspired him to become a biology major at Northern Arizona University, which he then continued at East Tennessee State University after serving a two year church mission. At ETSU, he continued to work with his hands by pursuing a minor in jewelry and metalsmithing. This naturally evolved into an interest in dentistry which combined his love of biology and crafting with his hands.

 

During his time at ETSU he met and married his lovely wife Brandy and they started a family. He then attended the Case School of Dental Medicine in Cleveland, Ohio and graduated with honors. After graduation he worked as a dentist in the Verde Valley of Arizona, and eventually acquired a dental practice there. While in the Verde Valley he enjoyed his time serving his patients and living in the beauty of the surrounding mountains.

 

Dr. Arnall was introduced to IV sedation during his time practicing in Arizona and it became his next professional love. He noticed however that many patients with deeply rooted anxieties and those with complex special needs required a level of anesthesia beyond what he then could provide. This drove him to take his love of anesthesia farther than just IV sedation. He was accepted to New York University Langone-Brooklyn for a three year anesthesia residency. He moved his wife and four kids, to the Big Apple where he learned the skills to safely provide all types of anesthesia in both office based and hospital settings. There he enjoyed treating thousands of patients, many of which were children and those with complex special needs.

 

Dr. Arnall loves serving the good people of Michigan, and providing an increased access to care in our communities is one of his top priorities. To Dr. Arnall anesthesia is nothing less than providing profound comfort and mercy to those that need it most.
