Dr Grant & Family photo


Dr. Grant Kollenborn is coming to us from New Orleans, Louisiana. He has practiced general dentistry in the New Orleans area for 7 years. After obtaining his doctorate of dental surgery degree from Louisiana State University, he completed a restorative implant fellowship to further his dental expertise. Dr. Kollenborn met his wife in the valley, and they lived in Jackson for many years, spending their time fly fishing and skiing together. They are both excited to return with their sons, Clay and Drew and puppy “Copper”.

Dr. Kollenborn and his family embrace all that the Tetons have to offer. They enjoy exploring the banks of the Snake River as well as spending their days on the slopes.

Dr. Kollenborn looks forward to providing you with quality care in a warm, friendly environment. He strives to create a comfortable atmosphere while incorporating the tools of a modern dental practice.
