Getting to Know Us




Dr. Killeen graduated from Louisiana State University School of Dentistry in 1975. He has been a practicing Slidell dentist since 1977. He is very active in continuing his education especially in the area of dental implants, crowns and dentures, cosmetic restorations, veneers and whitening your teeth for a lighter and brighter smile. Dr. Killeen is highly trained in full assessment and treatment of your dental problems and works with a team of doctors to assure you that you are receiving the highest quality care available using this multi-disciplinary or "circle of care" approach.

Lana retired from teaching to assist Dr. Killeen with patient care.  She is highly trained as our patient care and education coordinator.  She will explain your treatment in detail, answering any questions you may have and will coordinate your appointments within our office and with specialists. She will guide you through, step-by-step, your customized treatment plan. Lana also serves as the administrator of our Dental Assistant Training Program. Lana has been a dental professional since 1986.
