Practice overview
About the practice
The Tooth Ferry is a pediatric dental practice on Holman Road NW at 15th Avenue in Seattle’s Crown Hill neighbourhood, just north of Ballard. Dr. Megan Posthuma is the owner and sole dentist. The office describes itself as playful but professional, with a Pacific Northwest theme taken from Dr. Posthuma’s childhood ferry rides to the San Juan Islands.
Dentist
Dr. Megan Posthuma, DDS earned a biology degree and her DDS at the University of Southern California. She completed a one-year AEGD residency at a federally qualified community health centre in Walla Walla, training in behaviour management and sedation dentistry, then a 25-month hospital-based pediatric residency at Rady Children’s Hospital with UCLA oversight, where about 90% of her patients had special needs. She has advanced training from the Autism Discovery Institute and has been board-certified in pediatric dentistry since 2016.
Her approach favours minimally invasive, non-surgical treatment where a case allows it, which can reduce or remove the need for anaesthesia when treating cavities.
