Dr. Lacosse says...

Dr Robert LaCosse is the first and still the only general dentist north of Minneapolis to have been awarded full accreditation from the American Academy of Cosmetic Dentistry. With over 6000 members, the AACD is the largest organization in the world dedicated to the art and science of cosmetic dentistry and only 300 members have reached the level of accreditation.

Dr LaCosse runs a general dental practice with a strong emphasis on the particular skills required for achieving excellent results in cosmetic dentistry and complex restorative or reconstructive dental cases. Comfort, respect, trust and value are stressed in all of his procedures.

Dr LaCosse has also been awarded the prestigious Fellowship in the Academy of General Dentistry and the invitation only Fellowship in the International Academy of Dental Facial Esthetics. He is the only dentist in the Midwest to hold all of these honors at the same time. In addition, he was the first dentist in Duluth to complete the Post Graduate Continuum in Esthetic Dentistry at the University of Minnesota. He is a published author on the topic of Cosmetic Dentistry, a respected lecturer in Cosmetic Dentistry topics at several organizations including the University of Minnesota, and is a contributor for dental topics at KBJR news.

As owner of the Lake Dental Group in Duluth, his primary goal is to work together with each patient in a comprehensive and caring way to achieve the best possible dental care. New patients are always welcome.
