A message from the director

Thank you for your interest in Northwest Dental Residency. Our sponsoring organization is Yakima Valley Farm Workers Clinic, a large multi-site community health center with clinics in Washington and Oregon. The residency clinical sites are at Yakima Valley Farm Workers Clinic in Yakima, Toppenish, and Grandview, along with Columbia Valley Community Health sites in Wenatchee and Chelan.

Each resident is assigned to one clinic but will travel to various sites on occasion to meet training needs. We offer a stipend of $48,000 plus a $3,000 housing allowance. Yakima Valley Farm Workers Clinic is also one of the clinical locations for the NYU Langone Pediatric Dental Residency and sponsors various medical residency programs.

Some of the didactic courses are conducted via video conferencing, with others being done by local and regional specialists and dentists.

Each resident will be assigned a mentoring dentist who will have a one-on-one relationship with the resident during the year. The mentoring dentist will be responsible to ensure the resident is assigned the appropriate cases and professional experiences desired.

We teach a strong behavior management philosophy to pediatric dentistry. We use rotary endodontic techniques and offer a rich experience in endodontic treatment that includes molar endodontics. We have state of the art equipment in modern facilities, an electronic dental record, digital radiographs, and have additional equipment such as clinical microscopes, and soft tissue lasers.

Our patient population is primarily low-income with tremendous restorative (amalgam when needed, but a majority of posterior composites) and oral surgery needs. A resident will be able to treat a large number of medically compromised patients and have a variety of clinical procedures to work on. Like many AEGD programs, the number of available patients for fixed prosthodontic cases is limited, but we feel we can offer a good selection of those as well. If you would like an idea of the numbers and varieties of services our residents have done, please check out the list of clinical experiences.

I am a past member of the Washington State Dental Quality Assurance Commission, the regulatory board for the state, and I believe it’s important to give residents a very practical and up-to-date view of ethics, risk management, and quality of care issues.

The state of Washington passed legislation to offer a dental license to anyone who successfully completes an AEGD in our state. Residents must obtain a Washington state limited dental residence license, active on the first day of the residency academic year. The fee for this license is reimbursed to the residency. You would not need to meet any additional criteria beyond what we require for the residency to apply for a limited dental resident license.

It is difficult to explain the full experience we offer in one short message. If you would like we could discuss the program further by phone, a good number to reach me at is (509) 949-2278. I can call you as well if you send me your contact information.

Thank you for your interest!
