Established in 1921 as one of the first orthodontic practices in Pennsylvania, our doctors and team members remain dedicated to patient care, education and treating each other and our patients with dignity and respect. The LOA team is comprised of highly trained, dedicated, and happy people with a passion for Orthodontics. We are here to ensure beautiful, healthy smiles in a setting where our patients feel well-cared for. For nearly a century, our motto has been to "always put the patient first". Today, Lancaster Orthodontic Associates continues the excellent tradition of Long Orthodontic Associates and our founding father Dr. H.K. Cooper.
