Robert Henry Johnson, 90, is believed to be the oldest practicing dentist in the United States.
Johnson, who was born in 1931 during the Great Depression, has practiced his profession for over 70 years and has no plans of retiring anytime soon, according to KWTX.
Johnson was born and raised 10 miles south of Goldthwaite in 1931 to farming parents. He decided that he would pursue a career in dentistry at the tender age of 12 after encountering two successful dentists in Goldthwaite.
Johnson graduated from Baylor University in 1952 and later graduated from Baylor Dental School in 1956.
Johnson first worked at Biggs Airforce Base, now named Biggs Army Airfield, located in El Paso before starting his own dentistry in Big Spring, Texas, working there for 13 years, according to KWTX.
Johnson opened up his one-man practice in Brownwood, Texas, in 1970, where he continues his practice to this day.
Johnson attributes his endurance and excellent health to his love for his profession, good genes, sitting as often as possible while working, and two vodkas an evening with his wife, Pat. Johnson says that he still golfs and works on his ranch almost daily.
Johnson considers his parties to be like family. “Money is not the answer to the deal. It’s the love of your patients that you’ve had for 50 years when they come in and say, ‘what am I going to do when you retire?’ And they mean it,” said Johnson to KWTX.
Johnson will turn 91 on November 25.
His practice is well-reviewed, with one patient writing, “What a great staff and got to love his expertise and his sense of humor. Knows his business and [is] a no nonsense kind of guy.”
Johnson’s license to practice as a dentist is valid through August 2023. He has never faced disciplinary action throughout his long career, according to information retrieved from the Texas State Board of Dental Examiners.
