About
Dr. Thomas Loomis earned his Bachelor of Arts in Biology from Anderson University in Anderson, Indiana, before completing his Doctorate of Medicine at the University of Michigan in 1994. He trained in general surgery at the Medical College of Wisconsin, then pursued a second residency in family medicine at Saint Michael Hospital in Milwaukee, finishing in 1997. That deliberate shift from surgery to primary care came from a simple realization: he missed the ongoing relationships that define good doctoring. He holds board certification from the American Board of Family Medicine and membership in the American Academy of Family Physicians. Dr. Loomis practices at Northern Michigan Hospital and holds his Michigan medical license.
Raised in a rural Michigan community, Dr. Loomis grew up seeing the same family physician who delivered him. That experience shaped a care philosophy he still carries: the best doctors master both the art and the science of medicine. He has served the Petoskey and Harbor Springs region for more than twenty years. He has a particular talent for translating complex medical concepts into plain, accessible language. He also holds a special clinical interest in office-based surgical procedures. An avid skier, Dr. Loomis weaves fitness encouragement into patient conversations whenever he can.
