Advanced Education in General Dentistry (AEGD)
Postdoctoral Residency Program

2023-2024 candidate applications are not yet open.

Program Overview

A Unique Collaborative Program in a Nonprofit Atmosphere

Apple Tree Dental’s AEGD residency program operates in affiliation with NYU Langone Dental Medicine Postdoctoral Residency Programs (NYU Langone Dental Medicine) to offer an accredited AEGD program.  This program gives two residents a one-year training opportunity at either Apple Tree’s Mounds View Center for Dental Health, which is located just ten minutes north of the Twin Cities of Minneapolis and St. Paul, or at Apple Tree’s Fergus Falls Center for Dental Health, which is located in a beautiful rural location in Otter Tail County.

As a nonprofit community clinic and critical access provider, Apple Tree addresses the unmet dental care needs of underserved individuals of all ages and abilities, and provides a dental home for many low-income children and families, adults with disabilities, persons with mental health conditions, veterans, frail elders, and others with special needs.  Approximately 80% of Apple Tree’s patients are on medical assistance programs.  Apple Tree has accessible treatment rooms, oral surgery suites equipped with IV sedation & general anesthesia capabilities, and adjacent recovery areas.

Graduates of this program become more confident practitioners with bright futures in private practice, community clinics, and public health settings, or may go on to specialty training or to careers in academic dentistry.  The residents’ confidence in their diagnostic and restorative skills, as well as their ability to interact with others across the health care spectrum in obtaining useful medical consultations and making necessary referrals, will mature exponentially over the residency year!  Equally, the residents’ self-assurance in individualizing preventive oral health plans and communicating proficiently with a wide range of patients and educating them will become second nature.  They will receive experiences in assessing and managing dental trauma, and become adept and efficient at managing patients’ dental pain and infections.

Enriching Experiences in Beautiful Places

Minnesota is affectionately known as the “North Star State” and the “Land of 10,000 Lakes.”  With a population of roughly 5.6 million residents, Minnesota has a high standard of living, a great education system and beautiful natural scenery.  Minnesota boasts a number of exciting things to do outdoors and has 66 state parks, Voyager National Park, the Boundary Waters Canoe Area, and more than 4,000 campsites. Its oldest state park was established in 1891 at Lake Itasca, the headwaters of the Mississippi River. Several scenic roadways provide breathtaking views of the river bluffs and natural habitat of the Mississippi and Minnesota rivers, the “North Shore” of Lake Superior, and beautiful vistas of Minnesota’s southern farming region, and the pine and deciduous tree forests and lakes of northern MN.

During spring, summer and fall, Minnesotans enjoy lake time and activities such as water skiing, boating, kayaking, canoeing, fishing, and more.  Hiking and biking opportunities are never scarce, particularly with a number of designated paths throughout the metropolitan area. Minneapolis is known as the “City of Lakes” and boasts miles of pathways connecting all the lakes for eager bikers and hikers. In the wintertime, Minnesotans engage in ice and snow sports, including skating, skiing, snowshoeing, snowmobiling, ice fishing, hockey, curling, and more. 


Mounds View Center

Apple Tree’s Mounds View Center for dental health is only 15 minutes north of Minneapolis and St. Paul (also referred to as the “Twin Cities”). The Twin Cities metropolitan area, with a population of 3.6 million, is a center for business, industry, education, government, art, and transportation. It has a vibrant theater scene, as well as an impressive collection of eateries, breweries, and distilleries to satisfy any palette and budget. The Twin Cities are also home to the University of Minnesota and Golden Gopher athletic teams, and several professional sport teams, including the Twins (baseball), the Vikings (football), the Timberwolves (men’s basketball), the Lynx (women’s basketball), the Wild (hockey), and Minnesota United (soccer).

Near the Mounds View Center, residents can expect to find safe, quiet residential areas and easy driving access to freeways and highways. There is a public library, movie theater, bowling alley, community center, police station, coffee shop, grocery store, pharmacy, and a number of restaurants, all within walking distance to the Mounds View Center for Dental Health.
