Our Doctor

Dr. Brett Durbin graduated from the UMKC School of Dentistry in 2014 and spent his first 6 years of active practice serving rural communities in southern Missouri, including community clinics in West Plains, Cabool and Mansfield.

In 2020 Dr. Durbin took over the established practice of Dr. Charles Ryen, who has been providing dental care on the northside for nearly 40yrs. Both Drs. Durbin and Ryen share a strong desire to perpetuate their legacy of compassionate, quality care with a personal emphasis for all our Greater Springfield community patients, and so the practice has re-established as “Greater Springfield Dentistry” to affirm that commitment to serving all our local patients in this spirit.

Dr. Durbin is a recent past President of the Greater Springfield Dental Society and currently serves as our region’s representative on the Board of Trustees for the Missouri Dental Association. He is also a past member of the Board of Directors for the Missouri Academy of General Dentistry and a current member of the National New Dentist Committee for the Academy of General Dentistry. Dr. Durbin is a pre-Fellow candidate in the Academy of General Dentistry and has been honored by Fellowships in the American College of Dentists and the Pierre Fauchard Academy.

Brett is a native of the Springfield area, having attended K-12 in the suburb of Ozark and studied Biology, Chemistry and Religion as an undergraduate at Drury University. As an Eagle Scout he enjoys many forms of outdoor recreation as well as gardening and exercise. He is an active member of St. James Episcopal Church and also enjoys his cup of coffee, loves a good read and delights in lots of time with family and friends.

Dr. Durbin enjoys dentistry and personalized patient care and he hopes you will feel like a member of the “practice family” as our patient at GSD.
