A word from our patients

Excellent orthodontist. Beautiful clean office. Professional friendly staff. Dr. Kast is very talented, patient, and genuinely concerned. We took our 8 year old to him for treatment and we’re extremely satisfied and will be returning as the other children need orthodontic care.

I had an emergency this morning (one of my wires broke), and had to be seen by someone new since my regular ortho was out of town. Kast’s staff was so kind and helpful and they got me in right away. The office is clean, the workers are quick and friendly, and Dr. Kast is obviously very smart. He knew just what my ortho was trying to do and he got my wire fixed easily and correctly.
