Dr. Ronald Prehn's family has a longstanding history in the medical health field. His great-uncle, Dr. Fred C. Prehn, was a general surgeon in Wausau, Wis., from 1920 – 1960. His other great-uncle, Dr. Douglas T. Prehn, was a well known urologist in the U.S. Navy during the same period.
Prehn Dental Office in Wausau, Wisconsin, was started by Dr. Delos C. Prehn in 1921. For many years, Dr. Delos Prehn practiced above the Mueller Jewelry Store building, then Petran Jewelry Store, at 230 ½ Third Street in downtown Wausau. In 1953, after graduating from Marquette University School of Dentistry, Dr. Donald Prehn joined his father, Dr. Delos Prehn, and they practiced together for almost 17 years. Construction of the Wausau Mall destroyed the building, and the former Helke Funeral Home (a block away on Jefferson Street) was purchased in 1980 by Dr. Donald Prehn. This is where the present Prehn Dental Office is located. Dr. Donald Prehn was joined by his son, Dr. Frederick Prehn, in 1982, upon his graduation from Marquette University School of Dentistry. Dr. Ronald Prehn, also of Marquette, joined them for four years until Dr. Donald Prehn retired in 1993. Dr. Ronald Prehn moved to Texas to start a specialty practice in 1998. Dr. Frederick Prehn still runs the practice in Wausau. Their other brother, Dr. Robert B. Prehn, is a successful practicing otolaryngologist (ENT) surgeon in Oshkosh, Wisconsin.
Each consecutive generation has built upon the work of the previous generation and has kept the proven, time-honored techniques, combined with the newest in technology and procedure that dentistry benefits from today. Each generation has delivered — and is still delivering — high quality medical and dental care with competence, character and compassion.
