Welcome to Gilman Orthodontic Associates


Drs. Brian Gilman and Bonnie Yellin have been treating orthodontic patients in Happauge, NY since 1985. At Gilman Orthodontic Associates, our goal is to provide our patients with an orthodontic treatment that is enjoyable, comfortable, and nothing short of excellent. We treat our patients as if they were a part of our family, realizing effective results through personalized treatments.

Drs. Gilman and Yellin are highly-skilled and accomplished orthodontists, even achieving board certification and Diplomate of the Board of Orthodontics status. Together, they craft alluring and flourishing smiles for patients ranging from children to adults.

As a Gilman Orthodontics patient, you will receive a treatment plan that is designed to meet your individual needs. The treatment plan will rely on proven orthodontic techniques and the latest technology. Our office uses digital imaging technology such as the iTero to complete scans without the need for impressions, digital X-rays, and advanced computer graphics. We offer our patients a wide range of treatment options including traditional metal braces, ceramic (clear braces), and Invisalign® virtually invisible aligners to allow you experience your treatment your way.
