Meet Dr. Nack & Team

Dr. Nack attended Temple University and graduated in 1979 with a Bachelors degree in Biology. He then attended Temple University School of Dentistry where he received his Doctor of Dental Sciences (DDS) degree in 1983. In the early days of his career, Dr. Nack developed an interest in cosmetic dentistry and dental implants and over the years has taken many hours of continuing education to further those interests and refine his skills. Today, he maintains a general dental practice in Holland, PA that focuses on all aspects of restorative care with a cosmetic flare. He practices the team approach to quality care that combines his expertise as well as those of his team of specialists, when necessary, to create long-lasting, healthy smiles. Dr. Nack’s passion for dentistry is evident. He believes in educating his patients about the advantages of good dental health and that every patient deserves his undivided attention when diagnosing and discussing their needs. In addition to his practice, Dr. Nack is a Clinical Instructor of Restorative Dentistry at the Kornberg School of Dentistry at Temple University.
