William Moos, dds


Dr. Moos was born and raised in rural Wisconsin before transplanting to beautiful Montana. He attended Montana State University and received a Bachelors Degree in Cell Biology & Neuroscience. He then moved back to his home state to pursue his dental degree at Marquette University School of Dentistry. Currently, he is a member of the American Dental Association, Montana Dental Association and the Blue Ribbon Study Club. Dr. Moos always knew he would return to Bozeman and call it home to start his own Bozeman dental business. His intentions were to bring the “small town feel” he grew up with to his patients through his care. He has a strong drive to exceed your expectations and make your visit to the dentist an enjoyable one! When he’s not caring for patients, Dr. Moos finds enjoyment exploring the outdoors with his family!

Dr. Moos is a talented, experienced dentist who would love to care for you and your family. Come meet him today!
