Our guiding principles are compassion, integrity, and leadership through excellence. Together, we seek to: provide the absolute highest level of patient care, advance the science of medicine and dentistry through research, extend the art of surgery to the next generation through teaching, create a resource for our communities, and cultivate a positive and stimulating environment for our staff. Please contact us today for a consultation—we look forward to creating a specialized program to fit your needs!


Head and Neck Surgical Associates was founded over 25 years ago on a private practice model by Dr. Dierks and partner. Built upon a union of unique partnerships, HNSA started off with the support and expertise of a University based hospital (OHSU) and community based trauma center (Trauma Services, LLP). We began with the exclusive contract for all head and neck injuries, and provided coverage for all subspecialties of dentistry, oral and maxillofacial surgery, otolaryngology, and plastic surgery. From the beginning, we’ve been dedicated to serving the community through both education and good medicine. Today, we continue our tradition of excellence with our group of compassionate, skilled doctors.
