Meet Our Doctors
Dr. John W Rheney
Dr. John W. Rheney III was born in Charleston, South Carolina, and moved to Orangeburg at two months old when his parents, Dr. John W. Rheney Jr., MD, and Joyce Rheney, a nurse, established the first pediatric-only practice in Orangeburg. As the oldest of three siblings—Betsy, Bruce, and David—Dr. Rheney has lived in Orangeburg his entire life, aside from his academic years spent at Clemson University, where he graduated with honors with a B.S. in Zoology, and in Charleston, where he earned his DMD at MUSC School of Dentistry.
While at MUSC, Dr. Rheney III worked in the Graduate Research Center as an intern, researching the effects of Beta-Propranolol on heart muscle. He also gained practical experience in the Ambulatory Care Unit at Richland Memorial Hospital and completed rotations in the ER.
In 1981, Dr. Rheney III returned to Orangeburg with an uncertain path forward. After reaching out to local dentists and being advised they didn’t need assistance, he received a call from Don Collier, the president of First National Bank, who, along with Clarence Evans, facilitated the setup of his dental practice alongside Dr. Jimmy L. Gardner, DMD. Together, they opened a state-of-the-art dental facility across from what is now Orangeburg Prep School. As the area grew commercially, Dr. Rheney and Dr. Gardner eventually sold the property, and in 2000, Dr. Rheney moved his practice back to his roots on Cook Road.
Dr. Rheney III is married to Breta Ann Rheney, and together they have three daughters and six grandchildren. In his free time, he enjoys farming, hunting, fishing, and working on machinery—skills he finds akin to problem-solving dental challenges.
“I dearly love my staff and patients and am sometimes overwhelmed by the memories of those who have been with me for my 43 years of practice. It’s a blessing to now care for the grandchildren of patients who started with me all those years ago but are no longer here. Orangeburg has truly blessed me.” – Dr. John W. Rheney III
Dr. Ouida Marine
Dr. Ouida Marine was born and raised just outside of Charlotte, NC, in the small town of York, SC, near her family’s farm. She attended Clemson University, where she earned her degree in Animal and Veterinary Science with a minor in Business Administration, graduating in 2020. Driven by a passion for healthcare and serving others, she went on to earn her Doctorate of Dental Medicine from the Medical University of South Carolina in the spring of 2025.
Dr. Marine is dedicated to providing compassionate, patient-centered care and values the meaningful relationships she builds with every patient. Her goal is to create a welcoming, comfortable environment where patients feel truly cared for and confident in their dental experience.
Outside the dental office, Dr. Marine enjoys gardening, baking, discovering new music, and traveling to new places.

“Hands down…the BEST dentist I have ever been to. The whole experience was great…Fit me in the same day I called. Being greeted by Nikki and Joann when you walk in the door. I have terrible dental anxiety, and they always put my fears at ease. His Hygienist Kathy I can not even put into words how amazing she is..she’s personable, gives great advice, and makes you feel so comfortable, and you leave with your teeth squeaky clean. I don’t think she missed a spot. Dr. Rheney is patient, and gentle. Really listens to any issues or concerns you have, and gives you a good game plan step by step. Will never go to anyone else. Can not thank them enough! So if you are looking for an excellent dentist this is the place to go.”

“I’m a coward when it comes to dental work… actually, I’m a big baby, but I’ve been going to Dr. Rheney for years, and, unlike previous dentists, Dr. Rheney has taken my fears into great consideration! He is paitient with me (he’s a saint) and always ready with his quick wit just when I need it most. He’s a great dentist! For me, he is the perfect dentist. Dental work isn’t always pleasant, but he makes every attempt to make it as painless as possible, and I can’t think of a single time when I’ve left his office in pain! Thats a big win!
Dr. Rheney and his staff offer EXCELLENT services and his fees are beyond reasonable – even without having dental insurance!”
