About Us

Dr. Brennan O'Brien, a native of the U.S. Subic Bay Naval Base in the Philippines, has always been driven by a passion for dentistry. After graduating from Cathedral High School in 1999, Brennan pursued his academic journey with zeal, earning a bachelor's degree in Biological Science from Louisiana State University in 2003. His thirst for knowledge led him to the prestigious University of Mississippi School of Dentistry, where he obtained his Doctorate in Dental Medicine (DMD) in 2010.

Driven by a commitment to excellence, Brennan further honed his skills through 18 months of advanced dental education in Baton Rouge, Louisiana, completing the General Practice Residency (GPR) program at the Louisiana State University School of Dentistry. During his residency, he immersed himself in the complexities of hospital dentistry and gained invaluable experience in addressing the oral healthcare needs of medically compromised patients.

In January of 2012, fueled by a desire to serve his community and carry forward the legacy of excellence in dental care, Dr. O'Brien returned to Natchez. With a firm foundation built on his late grandfather's and father's dedication to dentistry, Brennan is committed to upholding the highest standards of care for his patients.

Driven by a genuine desire to make a positive difference in people's lives, Dr. O'Brien combines his expertise with a compassionate approach to dentistry. His patients appreciate his meticulous attention to detail, gentle demeanor, and commitment to delivering personalized care tailored to their individual needs.
