Thomas L. Kassube


"Our commitment is to provide the best possible periodontal treatment in a professional and friendly manner. The best part of my job is meeting and getting to know all of the wonderful people who come into our office for care."

Dr. Thomas L. Kassube has made a home and raised a family in Sioux Falls since 1981. He started the practice in part because no one in Sioux Falls or the surrounding region provided periodontal care.

He graduated from the University of Nebraska College of Dentistry in 1975 (yes, he's a Cornhusker fan) and then served in the US Army Dental Corps from 1975 to 1979. He received his Certificate of Periodontal Specialization from the University of Nebraska College of Dentistry in 1981.

During any spare hours, in between two sons and two daughters and a growing number of grandchildren, Dr Kassube and his wife enjoy spending time at their cabin in the Black Hills. Gardening, hunting and Cornhusker events are also an important part of his life.
