Dr. Ron Ko is originally from the far Pacific Northwest (PNW), Anchorage, Alaska. He moved down to Seattle to attend the University of Washington for undergrad and left the rain to obtain his dental degree at the Arizona School of Dentistry and Oral Health.
Dr. Ko is well versed in all areas of dentistry and is constantly partaking in continuing education to expand his knowledge of the field. He has extensive training in implants and root canals as well as fixed and removable prosthodontics (dentures, crowns, bridges). He is also very well connected with an elite group of local dental specialists (i.e. orthodontists, oral surgeons, endodontists, prosthodontists, periodontists) for any cases that may need additional love and attention.
When Dr. Ko is not at his practice, he can be seen with his family outdoors at public parks, museums, and zoos. When he is not with his family, you'll find him with a group of friends watching football, basketball, or playing a round of golf. He enjoys traveling, learning about different cultures, and searching for tasty meals.
