About Us

O'Leary Orthodontics has been proud to serve the people and families of Irmo and Chapin with beautiful healthy smiles and a great orthodontic experience since 2001. Dr. Brian C. O'Leary is well known in our community as a professional and talented doctor who provides personalized care based on individual needs.

Our range of orthodontic services ensures that all patients receive the treatment that is right for them. We offer traditional appliances for orthodontic correction, including braces for children, teens, and adults. We utilize standard, clear, and self-ligating brackets, as well as treatments using Invisalign® aligners when appropriate.

Your whole family will love coming to see us! Our staff personally greets every patient and parent as they walk in, and our reception area has free coffee and hot chocolate as well as newspapers and current magazines. We also have family-friendly programming on our TV and a game room for the kids! Families can come in and relax, knowing that they will always be welcomed in our office, and are ensured the best care available.

Meet Our Doctor

In my practice, my staff and I truly enjoy working in orthodontics. We go the extra mile to make our patients feel right at home and have a great time at every visit. Braces can be fun and rewarding, and I want my patients to have a positive orthodontic experience that results in a beautiful, lasting smile!

Before I became an orthodontist, I grew up in Irmo and graduated from Irmo High School. I then attended Virginia Tech, where I earned my Bachelor of Science Degree in Industrial Engineering. Afterwards, I went to the Medical University of South Carolina for my Doctorate of Dental Medicine. Finally, I completed my MS in Orthodontics and Dentofacial Orthopedics at West Virginia University.

I love serving the people of my hometown, and am proud to have my practice here in our community. I have three wonderful children named Lilly-Margaret, Eleanor, and Bradley. When I am not in the office, I enjoy cycling, playing golf, playing guitar or piano, and of course, spending time with my family!

Meet Our Staff

I have been in orthodontics for 30 years. I have assisted Dr. O'Leary and Dr. Herrington in many different roles throughout the office. I love getting to know my patients along with their families. Working here with Dr. O'leary, Dr. Herrington and our amazing staff makes every day a great day! We are one fun family!

I live in West Columbia with my wonderful husband Stephen and we have two amazing kids, Reese and Ryann. I also have two fur babies, a yellow lab named Bindi and a cat named Journey. We love to travel and spend time with our awesome family and friends.

I assist patients with scheduling appointments, creating fun contests in the office, and making sure everything flows smoothly. I am brand new to working in ortho but it has been by far the best job. I could not ask for better people to work with or a better doctor to work for.

Family means the absolute world to me so I spend as much time as I can with them. My boyfriend and I love the outdoors and doing projects around the house together. You can usually find me somewhere by the water on warm summer days or enjoying a relaxing night at home.

I assist Dr. O'Leary and Dr. Herrington with bonding, help complete patient treatment, and educate our patients on their treatment. I love getting to know our patients and working with our wonderful team. We always have so much fun in our office. Everyone that works here loves to laugh! Dr. O’Leary and Dr. Herrington are wonderful people and great orthodontists. They care for their patients, and staff, like family.

My husband Paul and I have three children, Caroline, Katy, and Paul-Joseph, and two dogs named Bud and Moose. When I’m not in the office, I enjoy playing tennis, horseback riding, and being a mom.

I am the financial coordinator for Dr. O'Leary and Dr. Herrington. I handle all of the insurance and finances and have been in the orthodontic field for more than 25 years. I love getting to know all of our patients and parents and assisting them with their financial needs and questions. We have an amazing team that I love working with.

I live in the northeast part of Columbia with my two cats. I have three children and six grandchildren with whom I love spending time. I also love to shop and work in the yard on the weekends.

Hi everyone! Here at O’Leary, I help ensure the flow of appointments so the clinic runs successfully each day. Whether it be clipping a wire, changing your colored ties, or removing braces, I’ll be right by your side throughout treatment! I take great pride in knowing I’m assisting in making your smile the best it can be! I love seeing the transition from start to finish and how much it can impact the confidence of the patients. I also find it really rewarding to get to know the patients and their families!

Something I really value about working at O’Leary Orthodontics is that our team is so strong because we truly are a family, not just coworkers. In my free time, I enjoy spending time with my family, reading books, and relaxing on the beach.

I am so happy to be here at O'Leary with this great staff and awesome doctor. I have been a clinical orthodontic assistant for many years. I truly love what I do. Working with terrific patients makes every day an amazing day at work.

My husband and I live in Chapin with our youngest and very talented daughter Amelia. We have another beautiful daughter, Aubrey, that has recently made us grandparents to a handsome grandson, Asher.

Hi, I’m Gena! I’m newer to the O’Leary crew and have been welcomed into this family by our amazing staff and patients. Since my treatment in 2015, I have known that I wanted to work in orthodontics and I am so happy that I get to help all of our patients transform their smiles! I assist Dr. O’Leary with all things regarding your braces or aligner treatment from start to finish which is extremely rewarding.

My wonderful husband Oliver and I live in West Columbia with our rambunctious fur baby, Luna. We enjoy spending time together and with our families.

I've been with O'Leary Orthodontics for three years and can honestly say that I've never enjoyed a job more. Our team works together as if we're a well-oiled machine. We have lots of laughs, more jokes than we can count, and best of all friends that have turned into family.

I live in Lexington close to Lake Murray. I enjoy spending time with my siblings and their children by the pool or visiting Virginia Hilton Park. I love to cook for my family, and seeing the satisfaction on their faces makes this chef very happy. I'm a student at Midlands Tech and aspire to further my career in the orthodontic field.

I assist Dr. O'Leary and Dr. Herrington with photographs/x-rays and scanning patients for appliances and Invisalign. I love working here because I have co-workers that are now family. Since joining the O'Leary team I've discovered a passion for teeth which is why I'm attending MTC to become a dental hygienist.

My boyfriend and I recently moved to the Ballentine area with our fur baby, Marley. I spend my free time between my kitchen and garden. I enjoy the Game of Thrones series and fantasy fiction novels.
