Kazuyo Ryno

Kazuyo Ryno

Registered Dental Hygienist

My name is Kazi, and I was born on the Japanese island of Hokkaido near the city of Sapporo. I earned a Bachelor's degree in Japanese literature from Fuji Women's College, and I attended Marian College in Indiana for one school year through a foreign study program. I worked in IT in Japan after graduating from college but moved to Seattle (my husband's home town) in 2004. I studied medical assisting at Seattle Vocational Institute and worked in Redmond as a MA. After staying home for several years to raise our two sons, I studied at Lake Washington Institute of Technology in order to earn my license as a Registered Dental Hygienist.

The aspect of dental hygiene that I find most rewarding is educating patients in steps to improve and maintain oral health. Having seen some of my own relatives lose their teeth at an early age due to the lack of professional oral care, I feel it is extremely important to look after the well-being of my patients and to accommodate their needs to the best of my ability.

I enjoy gardening, playing the piano, reading, yoga, sewing and knitting. My family and I love to find opportunities to ride bicycles and to hike the Northwest trails.
