About Us

Evergreen Hospital Dentistry was formed to address the unique dental care requirements of
individuals of all ages with special health care needs. Recognizing that many patients with
developmental or medical challenges face significant barriers to receiving routine and
comprehensive dental care, our group aims to provide compassionate, specialized services
tailored to these individuals.


Our Purpose
The primary purpose of our group is to create a safe and supportive environment where patients can receive comprehensive dental treatment. We understand that these patients may experience anxiety, sensory sensitivities, or medical complications that can complicate
traditional dental visits. By utilizing sedation dentistry techniques, we can ensure that each
patient receives the care they need without undue stress or discomfort.
 

Our Approach
We take a holistic and patient-centered approach, involving a multidisciplinary team of dental professionals, medical specialists, and support staff. This collaboration ensures that we are fully equipped to meet the diverse needs of our patients. Our team is trained in the latest sedation techniques and best practices for managing special health care needs, allowing us to provide high-quality care tailored to individual circumstances.


Commitment to Education and Advocacy
In addition to providing dental care, our group is committed to educating families, caregivers, and the community about the importance of oral health for our patients. We advocate for accessible dental services and work to raise awareness about the unique challenges faced by these patients.

Introducing Dr. Michael J. Dienberg, a seasoned dentist with a rich and varied background. After completing his dental education at Marquette University in Milwaukee, WI, Dr. Dienberg pursued advanced hospital-based training at UAMS (University of Arkansas for Medical Sciences) and ACH (Arkansas Children’s Hospital).During his hospital training and clinical practice, he had the exceptional opportunity to work alongside world-class

practitioners in various pediatric specialties, refining his surgical and clinical skills on patients of all ages. From wisdom teeth extractions to infant lingual and labial frenectomy (tongue-tie and lip-tie releases), he performed a wide range of procedures in diverse settings, including inpatient, ambulatory/outpatient, and operating rooms, all while providing sedation to ensure patient comfort and safety.

 

Beginning his career at Arkansas Children’s Hospital in Little Rock, AR, Dr. Dienberg served as both a hospital dentist and faculty for UAMS and University of Tennessee dental residents. Specializing in treating patients with cleft lip and palate and craniofacial anomalies, he earned certification in providing NasoAlveolar Molding (NAM) for infants, garnering invaluable experience and recognition for his dedication to the Arkansas community.

 

With extensive experience, Dr. Dienberg later moved to the Pacific Northwest (PNW), where he assumed the role of Hospital Site Director for Adult Hospital Dentistry Residency at OHSU (Oregon Health & Science University). Currently, he holds a clinical faculty position at OHSU’s Otolaryngology — Head and Neck Surgery Department, actively participating in the care of head and neck cancer patients. Dr. Dienberg’s commitment to patient care extends to treating individuals with craniofacial anomalies, cleft lip palate, special needs, and medically complex conditions, tailoring his approach to meet their unique needs. He is able to

serve patients in a hospital setting with Evergreen Hospital Dentistry.

 

Dr. Dienberg is trained and certified in IV Moderate Sedation in both Oregon and Washington.
