For Drs. Justin Kleinman and Sean O’Sullivan, providing personal care in a warm setting is their number one goal, while also using the most advanced techniques to reduce treatment time and discomfort. Their newly renovated state-of-the art practice is the only dual-specialty dental practice in Carroll County.

Dr. Kleinman, a board-certified periodontist, received his dental degree from the University of Pennsylvania, his certificate in periodontics from the University of Maryland and has also published papers in multiple peer-reviewed journals. Dr. Kleinman is certified in the LANAP procedure, Pinhole Surgical Technique for gum recession, and the All-On-Four same-day full-arch dental procedure.

Dr. O’Sullivan, a board-certified endodontist, received his dental degree from the University of Maryland Dental School, and did his endodontic residency at Virginia Commonwealth University.

Both Dr. O’Sullivan and Dr. Kleinman have been consistently named to Baltimore’s “Top Dentist” list for many years.
