Robert Lanning

Lab Technician

Bob brings the artistic nature to the practice. His fabrication skills in creating partials, dentures, night guards, bleaching trays, and surgical stents are impeccable. These skills can be attributed to his 35 years of experience and flawless attention to detail. Dr. Horn has been lucky enough to work with Bob since the beginning; he came with the original building! When Bob is not customizing our patients' new smiles, he is at home with his wife, visiting with his two children, or possibly creating remarkable wood carvings. Bob is happiest when he is creating.
