Dr. Landwehr earned his D.D.S. at the University of Minnesota in 1994. From there he completed training in two dental specialties. First, he earned an M.S. degree and certificate in oral and maxillofacial pathology at The Ohio State University in 1997 and then completed specialty training in endodontics at the University of Michigan in 1999.
Dr. Landwehr has been in private practice since 1999 in Wisconsin. Though his practice focuses on endodontics, his dual certification in endodontics and oral pathology makes him uniquely qualified to diagnose sources of oral pain. He has presented case studies and research findings both nationally and internationally. In addition, he has published several articles in various peer reviewed journals and served as an evidence reviewer for the American Dental Association. He is also Chief of Endodontics for the Meriter Hospital general practice residency program in Madison.
